3.5mm Jack Audio low? - Sprint HTC EVO 4G LTE

I notice that the audio from my aux jack is significantly lower than my old evo or wife's iPhone. Is this normal or do I have a defect?

Audio IS lower
... but not horribly low.
Both the audio out of my 3.5mm jack and the audio out of the speaker are quite a bit lower than my og evo. It's not anything like a deal breaker though.

Wow and I thought it was going crazy for noticing this... I also noticed it when using a bluetooth headset. It's not A LOT lower, but it's definitely noticeable

It appears that this only happens in 3rd party music apps. Htc's music app sound fine.
There is a noticeable difference when I'm listening to music in the car. It's not so bad when I use headphones.
Music does sound better through BT in my Prius though. I might have to pick up the HTC BT adapter for my other car.

Bluetooth streaming seemed great volume on ford sync but aux cable for my other car is considerably lower than my evo 3D was. I do notice the beats by dre makes it sounds great. I might try installing equalizer and cranking that up will prob help but prob will have to shut the beats by dre off then.

I've always noticed that the HTC phones I've had don't have very loud volumes for headphones. I use earbuds, so it's not an issue for me. Beats does make it louder, but I don't think it necessarily improves the quality of the sound.
I recall reading an article on either Engadget or Ars about what Beats actually does.

I'm experiencing the same issue. Does anyone know of an app or other fix to boost the volume, more specifically for me the volume of the speaker, because it's a little quite when I'm using the Navigation app. I remember a long time ago when I was surfing around, the was a way to over clock the speakers on the EVO 4G but I never needed it or tried it. Let me know if anyone knows anything like this for EVO LTE?

I was also having very low sound compared to my OG EVO. I installed the free equalizer app and have it maxed out(up to 4 for free app) and it does boost the sound a bit. I think you need to have it running in the background all the time which is gonna suck for battery life. If not you have to enable the equalizer every time you want to listen to something which is a pain. Anyone know of an app that will automatically start when music app, GPS etc are turned on?

One thing I had on my G2x because the output was horrifically low, there's an app called volume booster, actually a couple and it's nice because it stays off until you plug in headphones or an aux cable.

I use my auxiliary port on my receiver in my car for audio and calls and have noticed that the sound from my music app (Spotify) is just a bit lower than on my 3D. There seems to be a much bigger difference in the volume for phone calls though. It seems much lower. When I get a call while I'm listening to music, I've got to turn the volume way up in order to really hear anything. When the call ends, I've got to remember to quickly turn down the volume or my music will come back on super loud. Pretty annoying.

[Q] Bluetooth Audio Quality

Question,
Using bluetooth to play audio from Pandora sounds terrible. Lots of static, studdering, skipping, cut outs.
If i use a stereo cable it sounds great, so that rules out software.
My atrix sounded gorgeous over blue tooth, so that rules out the equipment.
Anyone else have any sound quality issues with the bluetooth?
No issue so far, use for about 4 hours a day for conference calls and then pandora/slacker or doubletwist for 2-3 hours more. Using Samsung sbh600 bluetooth.

I use A2DP stereo streaming to two different devices (car and supertooth disco) and it sound excellent! Much better than my old evo and just as good as the nexus S I had for a while.
If you are using wifi for the connection to Pandora, try switching to 3G or 4G. Wifi and bluetooth can interfere with each other as they use the same frequency. I haven't had any issues, but have seen it before with other devices.

I noticed the same thing today streaming to my kenwood unit. My droid X had flawless sound, this was exactly as you described. Any fix yet?
One thing I noticed, my X had a check box for an enhanced bluetooth audio quality....not sure if that made a difference or not.
Been using the phone in my car with my alpine deck without issue. I have the add-on bluetooth from alpine and it works really good with the phone. Randomly the music cuts out for a second but my old blackberry did the same thing, and so did my iPod Touch (2nd gen).
Shutting off the wifi on the phone isn't a bad idea... might give that a shot to see if that helps your issue? My blackberry would randomly distort the music. I would close pandora and do a battery pull then it would usually be back to "normal".
I have the same issue with my Clarion deck. Of course...I've somewhat convinced myself the speakers are a bit blown...but it's worse on BT than wired. From what I've been able to read there is a "bitpool" setting which controls the quality, and by default it's pretty low in the 30's, while it can go up to the 50's and the sound quality is noticeably different. CM fixes this from what I've read, but that's all. Apparently Blackberry has a higher setting by default, and each manufacturer can set their's different.
I'm hoping that a combination of new speakers and CM7 will remedy my issue.
interesting I've got a pioneer premier DEH-P710BT
and it sounds amazing
maybe look for a firmware update for your receiver?

mine is updated to their most current firmware. I'm more inclined to think it's a bad bluetooth stack like weiln12 mentions above. gonna try it out with my friends thunderbolt tonight and see if it is the same.
I also have a clarion deck and find the bluetooth audio quality to be horrific. I find it hard to believe that it's the head unit at fault since my old Droid1 sounded perfectly fine.
Is anyone aware of any roms or kernels that have a higher bitpool setting?
I haven't found any yet. I'm hoping when we see CM7 things will be better.

Sounds absolutely perfect on my Ford Sync audio.. I have a Scoche Bluetooth in my other car that I can test.. I haven't tested as it is currently off the road. I will let you know. With my Scoche and past phones I noticed the bluetooth is a little lower quality then the audio jack but not much and only with that unit.
I have a Motorola S305 headset that works very well with music (slacker, amazon mp3, and pandora). However, my bluetooth Samsung WEP570 sounds so bad, crackled, and quiet (even on max volume) that I don't even use it anymore for calls.

How is your call quality on the Ford sync? Specifically the incoming call volume.
I'm streaming Pandora to a MOTO roadster, then over fm to stereo, sounds great, no loss on the bass end either.
Have you tried another bt device?
Sent from my ADR6400L using XDA App
I personally have tried a few and have problems. However, I've tried multiple thunderbolts and they all sound the same on my kenwood. I've definitely read about HTC using less than stellar bluetooth on their units before, so I am assuming that is the case here. I guess it just works ok with some and not with others. Testing my X on the same kenwood unit I have and it's crystal clear with no distortion.
This has absolutely nothing to do with the quality of the bluetooth hardware itself. Bluetooth is a wireless digital transfer protocol, nothing more nothing less. It does nothing to the audio quality during it's transmission. Where we have a problem is in the amount of "space" (the bitpool) provided to send the information from your device to the receiver. The lower the bitpool, the less space is available for your music and the more it must be compressed. Motorola may infact provide a higher bitpool setting in their devices than HTC which would account for them sounding better and I also know that the X has a "Use High Quality Bluetooth Audio" setting, which I'm sure enables a higher bitpool.
The type of music you listen to also has a significant effect on how this sounds. If you listen to something that is sonicly simple (ie hip hop, pop, etc etc) it doesn't need as much "space" to sound good. However, when you switch over to music that has more going on like heavy metal, it needs more room.
I can give you a perfect example. I was listening to Rage Against the Machine today. In the slower parts of the songs, it sounded GREAT, but then when it picked up and the song got more involved there was a huge loss of fidelity and it didn't sound very good at all.
Now, for those of you who are happy with how yours sounds, that's awesome, but for those of us who are not, we simply just want to know of a way to adjust the bitpool setting or find a developer who is willing to code it in to their kernel/rom which I believe is what needs to happen.

Amen. You just summed up the situation perfectly. I forgot the X has the check box for high quality BT audio, that could very well be what makes it better. I'm going to check it out tonight w/o that checked and see how it fares. Not sure why HTC wouldn't have an option like that.
Just found a post here that seems very related. http://forum.xda-developers.com/showthread.php?t=708685
Apparently CM uses an open source BT stack that has good settings to use the higher bitpool but HTC chooses the Broadcom stack that utilizes a much lower bitpool as stated above. They don't seem to have a way to raise this value though....

i've had no issues. I use Pandora w/ high quality audio over BT into my Ford Sync system.
Sounds great. Somewhere between satellite radio and MP3 player SNR ratio.
Ironically my streaming audio is fine from mp3's i put on the SD, but IN CALL volume is much lower then i am used too, i have a Jabra BT530, its weird because the media volume is fine, but as soon as a call comes in i have to switch to the handset to hear the other end well.

Distortion when playing Pandora

Have any of you had a problem where Pandora plays sound overly-distorted? I used to think it was just because the headphone amplifier sucked bad, and couldn't drive my QC-1s, which is likely, but it even happens when plugged into my AUX on my vehicle's headunit. It's really bad on certain bass notes. It's almost as if Pandora is applying an EQ of sorts. I'm currently running Deck's v1.0 w/ Beats Audio flashed. I don't know how to control Beats Audio other than by enabling/disabling it in the Music Player. I also have not heard any audible difference when doings so.
When I had my Evo 4G, I always had a nice, loud, clean signal going to the same AUX port in my car. I would get crisp highs and tight bass--Pandora sounded as close to CD quality as you could get via a streaming app. The Music Player sounds a bit better, but still nothing like the Evo 4G. Have you guys noticed anything like this for the Evo 3Ds y'all own, and also have you seen a difference from one ROM to the next? I am almost pondering buying an MP3 player so I won't have to deal with this.
Thanks!

Does it sound like that when you play mp3s? Our just Pandora? either way, aux sucks.

Maybe try and put pandora on the high quality mode. Not sure if it already is or not, but i remember a long time ago this happened to me, and i am pretty sure that fixed it.
Same problem here. Talked to a car and audio guy. We decided the car and engine were actually interfering with Pandora and the signal through aux. Try twisting the aux up while playing. It makes it harder to be interfered
Sent from my PG86100 using xda premium
It's not the phone or AUX... well I mean the quality does SUCK compared to the Evo 4G even when playing MP3, but this is different. Pandora is playing distorted audio at any volume... It's so painful to hear, because I know it's destroying my speakers. Not all songs do it, either. I hope it is fixed. I am a Pandora One user, and I use HQ mode.
dude are you getting distortion from the phone's speakers also?? if so I think u have the same problem I have. Check this thread
http://forum.xda-developers.com/showthread.php?t=1268298
I'm not sure it's the same thing... this seems more like a Pandora issue itself. I guess I should try some other audio programs. The stock music player sounds fine.
It is indeed a problem with pandora itself.
I have a galaxy s2 and I am having the same exact problem. Bass heavy songs sound distorted even at low volume. Kick drums make your speakers or headphones sound as if theyre
blown.
Mp3's and any other streaming app such as tune in sound perfectly fine.
Pandora needs to address this issue asap.
On some songs Pandora gives some chirps at certain high frequencies. Doesn't happen with mp3 files.
Sent from my PG86100 using xda premium
It's a problem with at least the Evo series and Pandora. I've read it's the way Android handles the codec somewhere but it's usually fixed by going into settings, enabling "High Quality" (I think it's a radio button) then restarting pandora.
Usually I hear pops, clicks and occasional other noise. Bumped it to HQ and never had a problem. I've read it affects all android phones but I don't remember this issue on my old Nexus S or Epic 4G. Just on my HTC and my girl's Evo Shift.
never heard of this issue. weird.
I have tried setting it to HQ.... Doesn't work
Not an android device.... But similiar issue for tivo owners?
http://forums.tivo.com/pe/action/forums/displaypost?postID=10481248
Im sorry but it seems like this is a real issue and should be fixed.
High or low quality, no settings should make the bass distort like that. Especially at low volume.
Ive tried re-flashing different roms, uninstalling/installing pandora, every audio setting there is and any dsp audio app around. Nothing worked.

[Q] slight hissing with headphones?

Hi all,
Do you notice a slight hissing when you use headphones? I notice it if I'm playing soft music (like classical stuff)...when the music player first starts playing, it "powers up" the audio chip and I hear the hissing. Theres actually a slight high pitch sound to the hissing. If I pause it, the hissing sound stays on for a few seconds before the OS powers down the audio chip, then it goes silent.
Unpausing causes the hissing/highpitch to come back.
Do I have a crappy unit or are they all like this?
I noticed the same thing on my evo3d as well as the photon.
I just tried using a microphone/headphone, and I get the same hissing when the audio chip is used. The headphones are pretty good quality. I don't get this hiss from my mp3 players.
Anyone else?
I noticed it using pandora. Between songs there was static. It seemed to stop during playback.

music hiss with headphones
Anyone ever find a Photon 4g solution? I'm guessing it's just what you get from the current smartphone's DAC chip. I only really notice it on quiet music for the most part anyway. More annoying are the notification sound or pauses while playing music despite sound settings being adjusted right.. I think anyway.
I notice too but also when you plug it to power source it becomes louder.

It seems like the worst culprit in the noise enhancements is the surround function...when I turned just that off there was a big reduction in the hiss.
I got mine phone the week after thanksgiving and have heard that nearly nonstop... while driving I often have headphones from my old palm pre on and the high pitch sound is not unlike that which you hear when using headphones on a commercial airliner's 3.5mm seat headphone jack.
after extended periods it's very annoying and actually causes me to tense my shoulders and get a headache.
my enhancements are also off, it's just there, it's more prevalent when charging.
I hear it too thankfully its not too loud so although it's annoying. To the guy above me be careful driving with headphones in as it's illegal in most states to do so as it makes it harder to hear emergency vehicles.
Anyone try using winamp or another player to see if the hissing is happening with other players?

That high pitched whine you heard on the airline's headphone jack is the result of 400Hz AC power that all airplanes use.

Yes they all got it. Connecting to AC charger/power line will keep the noise being heard from headphone, as if the audio pipeline was activated in playing music, but USB connection doesn't trigger that. The hissing pitch is a flag but the noise level sounds within a common range - better turn off audio effects (bass enhancement was a good one and could be an exception). Positive thinking, since they said headphones are not good for long-time music listening, the audio chip is gonna enforce that.
I still like Moto Photon over other sprint android phones:
1. World phone with both CDMA and GSM. (was considering Samsung Galaxy Epic 4G but it has no GSM/SIM switch.)
2. 4G and powerful dual-core system (1 & 2 already exclude the rest options).
And 3. the most unique design of it:
"The Photon 4G's cut-off corners give the phone a decidedly more masculine look, as do the gunmetal gray border" - cnet.
"lots of tasteful details..." - engadget.com.
so does anyone know what the DAC in the photon actually is? i only ask because after 20 minutes or so with no luck with google and my query for dac in the mopho forums resulted with this thread.

Audio Whining/Squealing/Buzzing Noise

Just got my Rezound on Monday. It's my first HTC phone, and overall I love it... except for one problem.
When listening to music from the phone or Pandora radio, I notice a high pitched whine noise under the audio. It fluctuates between whining/buzzing/squealing and sounds like some kind of electrical interference. It's most noticeable during classical music or a quiet part of a song, or when switching MP3s/radio songs. The noise continues for about 2-4 seconds after stopping/pausing the song before it goes completely silent. It's bad enough that I've been getting headaches from it. I've tried multiple pairs of headphones and also toggling the Beats audio enhancement with no luck.
I saw a few threads where the Bionic had a similar problem. Anyone else experience this whining when listening to music through the 3.5mm jack on headphones or passing it through your car stereo?
Edit: I've now noticed that I can hear this noise even while the volume is muted, as long as some sort of audio is playing (MP3 from library or Pandora for example).
Yeah a bunch of us have it. It sounds like CPU noises and processing noises. Could be por shielding. I don't notice it that bad, and I've got reallllyy good ears (musician, too lol) and it doesn't bug me too much. But yeah, I can confirm its there. There's a thread on phandroid forums about it.
Sent from my ADR6425LVW using XDA App
Phew, I'm not crazy. I'm not a musician, but I guess I have really sensitive ears for it to bother me so much. It's especially obnoxious when hooked up through the car, since the whining doesn't seem to increase in loudness with the volume level, but the car volume DOES increase it.
A lot of people are reporting that the Bionic issue is/will be patched out. I contacted HTC but haven't heard back yet. I'm really hoping something can be done. My 2 year old OG Droid played audio without a hitch. : /

I've noticed the same background whining sound on two different Rezound units when playing music through earbuds. I haven't tried my Motorola Stereo Bluetooth headphones to see if I can hear it through those yet.
The Beats sound quality is good, but this background interfaces is killing it for me. At this point the Audio from the Droid Bionic sounds better when using the different EQ settings.
Pretty inexcusable for an audio focused phone.

I may be a lucky one but I get no background noise at all. That is with the included earbuds, Sony low end headphones, and through my aux in the car.
Now having said that I was initially getting some background noise in the car but changed the car charger and the noise went away. That was not a whine but more like static.

Which charger does not produce the noise? I'm getting worried about this noise. I'm switching carriers for this phone so I'm not sure what I'll do if it really bothers me. Mine arrives Tuesday and that's the day I'm driving 2.5 hours to Mom's house for Thanksgiving so I'll get a nice long chance to test it out in my car.

Belkin mini 5v 1a for lighter and usb
I tried two different brands of wired earbuds and a regular wired over-the-ear headphones and can hear the background whining sound with all of them. It doesn't matter if I'm using the default music player, Google Music, WinMap (or 3rd party player), I can also hear it when streaming YouTube videos.
But if I use my Motorola HT820 Stereo Bluetooth headphones, there is no whining sound, just a small background "hiss" that the Motorola HT820 always has done.
So it seems the background whining problem with the Rezound has more to due with using the 3.5mm headset jack for listening to music, as I don't hear it when using Stereo Bluetooth headphones.
Maybe someone else with Bluetooth Stereo headphones can double-check?

I would be curious if someone else could try this as well. In a response to my ticket regarding this HTC support suggested I try a bluetooth headset, I dont have one and they told me to go to the store and ask to try one. I dont plan on doing that but would be interesting if someone has one laying around already to try and confirm.
I tried removing my back cover and listening as well at their suggestion and that seems to take care of it as well so it may be an antennae issue.
I put the cover back on but have 4g off today to save some battery life and havent heard it yet while listening to music on my device, so it may even be the 4g signal interfering if someone else would like to try that as well.
my 4g is off and i hear the noise, so it's not the 4g radio
I notice it only when the music player is not playing any audio. When beats kicks in, the noise seems to go away.
Like when an album is done and the player has nothing to do, when the phone is connected to my truck stereo, I hear noise that changes in pitch with the RPMs.

Some of what you guys are describing, the stuff with car chargers, has to do with a ground loop. http://www.epanorama.net/documents/groundloop/index.html
Some of it sounds like poor shielding. This is the noise you hear when you have earphones plugged in and no audio is playing. The audio jack/circuitry on this phone is probably very poorly shielded as all of them probably are nowadays. A lot of this noise gets drowned out with louder music, which is might be what happens when Beats is on.
I would love to know objectively if this were better or worse than other phones but no one ever tests these things and I'm not gonna hold my breath for a phone that touts a real headphone amp, DAC, and superior signal to noise ratios, or anything a music lover (not just hip-hop) might care about.
The easiest way I've found to get around most of this is to use Bluetooth audio. It doesn't sound great by any stretch, but it has less noise than most jacks and doesn't have the ground loop issue.
All I know is there was no noise at all with my Incredible.
I was listening to sections of John Lennon's Rolling Stone Interview (recorded shortly after the breakup of the Beatles) via the YouTube app on my Rezound today. The noise would start right after one segment would end, and stop as soon as I selected the next one.

yep
i hear it when I am using the ibeats headset on calls, it is very annoying. However it only happens if I have the audio all the way up, after putting it down two times it goes away.
I tried a suggestion of turning on the Airplane Mode to kill data while using the music player, and I can still hear the backgtound whining interference sound. Even with a song playing, and turning the music volume all the way down to mute, I can still hear it in the background. But once I pause the song, the whinging stops a few seconds later. This happens while using any brand of wiered earbuds or headphones, not just the red ones that come included.
The only time I don't hear it on the Rezound is when using Bluetooth Stereo headphones.
Since I also just got the Droid Razr, I tried music playback on it, and it doesn't have any backgroud interference sounds, though the actual music quality still sounds better on the Rezound. Hopefully its an issue that can be resolved with a future software upgrade, but it might be a hardware issue that can't be fixed.

[Q] bluetooth audio streaming problem?

so i just got my htc rezound like 2 days ago and so far its wonderful (coming from a droid razr). the only stipulation im having is streaming audio via bluetooth to my car's stereo system (ford fusion with sync system). it sounds really crappy using the standard player htc gives you, but if you switch to amazon mp3's player it sounds good except for certain pitches and frequencies sound like crap. it almost sounds like crackling but not quite. gives it good bass back tho. so is there a way to fix this? i did unlock my phone like 4 hrs after getting it from the fedex guy. is there anything i can do to it go improve on the audio quality or is this gonna be a "wait for ICS and see" kinda deal?
Try PowerAmp or install a rom with DSP so you can tweak the audio settings.

k will give it a shot later tonight when i leave for work. i honestly dont think it has anything to do with the eq but i'll try it. i think its something with the bluetooth radio thats built in....maybe its just a crappy design idk.
any other ideas in the mean time? or anyone else having the same issue?
Never heard of this problem with differences between players.
Stream all day with my phone and only problems are with ICS not GB.
I have a Ford Focus (with sync) and mine sounds pretty good, but not as good as when I had full time beats on my EVO3D. They only thing I do is turn the volume up on the phone while its playing through the speakers. I do this but using the volume rocker on the side during playback. Its not as good as a CD but not too bad either. Tried to get the guy that fixed it on the 3D to look at the Rezound but he never responded to my PM. I have played with DSP Manager and you can get some improvement. Also other EQs exist in the market that can improve the quality.
<3 ford focus, are you saying it just lacks an equalizer's touch or does it crackle? =o
No Problem
I use the MotoROKR T505 for my car. Bluetooth stereo music over the car speakers is never a problem, regardless of using stock player, meridian, or poweramp.
Zone is right. Turn the volume all the way up. It took me awhile to figure this out. I think its radio interference that you're hearing.

well i tried poweramp from the market and it made some improvement...but still not as crisp as i'd like. it seems like with some of the higher frequencies over bluetooth it kind of mashes them together sort of. idk but coming from a droid razr i can definitely tell a difference. that phone was amazing when it came to audio quality over bluetooth. for now i guess i'll try to rig up the usb cord so my sync system can read the files from my phone or either buy a cheep aux input cord for my ford....until ICS is released....hopefully they made some type of improvement.
edit: i always have the volume maxed out via the rocker on the side....learned that day 1 of having an ipod long ago lol. the droid razr definitely puts out cd quality audio over bluetooth and i was kind of expecting this phone to do the same or better, not sub-par performance.
I wonder if that is the razr's 4.0 bluetooth that provided so
