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.

You need to go to sounds in the menu and turn off the noise enhancements that will eliminate the static I had the same problem

The setting was already disabled. So I don't think that's it.
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.
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.

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. : /

Oh man... I just ordered my Rezound this morning!
I hope it doesn't bother me.
if i can (and get super un-lazy, cuz i'm pretty lazy....) i'll record the noise from the earbuds into some of my sensitive recording mics to see if it picks it up to see if its the same noise. however, like i said, it doesn't bother me at all lol

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.

Yeah they all do it though. My incredible does it. Maybe its interference with the radio or the CPU.

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.
Hi all, I have a question about my GS2 that I bought recently.
I recently upgraded from a Nokia e71x. I'm a college student with a roommate, so I used a wired headset to talk to my gf quietly at night on the phone (mostly talking low voice or whispering). I bought the samsung earbud+mic that comes with other samsung phones and she couldn't hear me at all or my voice was breaking up. I also tried using a little adapter to use my old ear piece but still, same problem. So I tried to use the earpieces in the voice recorder app to see if it was the calling or the mics and it was picking up my voice with perfect quality!
is there any way to fix my phone so that it sends better voice quality or something? I tried using the mics on my brother's iPhone and they work perfectly fine on it :/
Does it break up when talking at normal volumes? It could be that low volume doesn't work well with that microphone.

Not at normal voices, just at much lower/quieter voices. I know the mic works because using it on voice recorder I can hear my voice perfectly. Also, I used the mics on my old Nokia and my brother's iPhone and it works great
Keep in mind during a phone call noise reduction will be active. Not active during voice recorder. The phone may be half trying to cancel out your voice because it thinks it's background noise.
If you can get noise reduction shut off, that particular microphone may work better. The apple headset shouldn't work as well with noise reduction as it's a different brand, enabling better low volume conversations.
To test it out, use the Samsung headset to call someone and hold the microphone next to the microphone on top of the phone and whisper, see how well it sounds.
Then move the phone a normal distance away from you and see how whispering sounds when the microphones on the phone are and aren't covered.
If it is noise reduction causing you trouble, holding it next to the top of the phone should make whispering pickup better. And covering up the phone mics at normal distance should also improve how whispering sounds.

I tried what you suggested with no difference between any of the mics. Also, I tried to turn off noise suppression, but apparently noise suppression is already off when you use a headset. Thanks, do you have any other advice?
Lol, I guess get an apple headset. I'm sure there might be other things you could do, but I can't think of any. Could just be the Samsung one is not as good as the apple one.

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
Sent from my EVO using XDA
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.
I am on my 3rd HTC One and the microphone is still having problems. I've read other threads and none seems to provide a solution to the problem. People I talk to can hear me if I use speakerphone or a headphone, but not if I'm just on the regular headset. People can't hear me unless I scream really loud. Does anyone know how to fix this? I'm on stock rom.
Dumb question, does your headset have a mic on it? And have you made sure the volume is turned up with it connected?

My buddy is having the same issue. He is now on 4.3 and is still experiencing this issue. It's been occurring for a some time now. He is completely stock/never rooted. The phone itself has horrible mic quality when using the phone alone. If he turns on speakerphone or uses a headset the quality is crystal clear.
We did some playing around on how he calls and apparently it may be an issue with the noise cancelling sensor on the back of the phone (small hole). Try calling someone while covering and not covering this hole to test if your call quality improves. He ended up hold his phone while cuffing the back and it seems to be better. It's a dumb solution, but hopefully it works for you.
Does anyone know if there is an option to turn off noise reduction on the phone? Sorry for the question, i do not own an HTC One.
