What is that high pitched intermittent sound coming from my headphone jack? - Asus Eee Pad Transformer Prime

I just bought a Prime with dock, upgraded to .21, and have an audio amp plugged into the headphone jack. There's a high pitch sound that goes on for around 10 seconds, then off for 10... sometimes its on for less (as little as a second). It's still there when the Prime's sound is muted. I'd say it's about as loud as a tone on a speakerphone at its lowest volume setting, but being a high pitch sound it carries throughout the house. I haven't had a chance to test it with earbuds yet.
Has anyone heard of this?

[Q] Headphone Amp for the transformer

I've been using my transformer for about 4 days now and I can say I'm really amazed by its sound qualities. Cracking-poping-sound-while-screen-off (which are solved by a slight overclock profile while screen off, at the expense of some battery life of course) issues aside the sound when its truly better than most stand alone PMP not to mention any iPod or the iPad itself.
So I'm wondering what headphone amp will be good match for it?, has anyone tried any?, thoughts?
Have you tried using Voodoo Sound? It does turn on headphone amp built in Transformer - but it could be not powerful enough for your particular headphones.
Fiio options?

[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.

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

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. : /

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.

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] Note's audio quality hiss?

I haven't seen this posted about the Note. Does anyone else have a bad hiss when listening to music? Using Google Music and spotify, there is a definite hiss in the background.
I realize the Note's audio chip isn't great but I wasn't expecting this. Coming from the Captivate, this is really annoying me at the moment.
I hear it only in headphones
I don't hear it on the speaker or via BT. Haven't used the headphone jack yet.
Right, only on headphones. Quite loud and intrusive. I listen to my good quality in-ears at work for hours every day. I can't believe just how crappy the sound is on this otherwise fantastic device.
Ok, you got me wondering so I put on a decent pair of over-the-ear cans and spent 10 minutes flipping through a half-dozen channels of XM (128 kbps streaming). Then 5 more minutes going through several high-quality MP3s (variable bitrate with a max of 224 kbps).
No hiss, no background noise at all during the soft parts. Cranked the volume up to max, no distortion. Very happy with the results - much better than my last phone, the onboard sound on that sucked.
I'm on the stock rom, are you using something else?
For mere there's some noise when I'm not listening to anything, but I only hear it on my headphones.
In car Hiss
have not noticed it with headphones...but.....While using the car dock, any pause in the music whether it be on Pandora, Google Music, or just no app selected, There is a really annoying hiss/feedback through the speakers in the car. This is using the audio output connected to my stereo's AUX input.
It's just like a bad ground "whine" on a stereo...speeds up and down with the car. Never did this before with any other phone/device, so I know it's the note or the dock. I have not tried connected directly to the headphone jack on the note, I'll have to try that out.
Yeah the skyrocket did that too. I have a video up on you tube of it.

As stock as can be here. The hiss is most apparent at the beginning of the track when it starts playing but no music yet. As soon as the track starts playing, you can here it click on with the hiss.
Did I get a defective one?
I'm using a very good pair of in-ears (UE700s). I'll try to dig up some cans later to try it. Maybe directing sound directly onto the ear drums via in-ears picks up the hiss better (less natural filtering?).
Another thought: is there an internal amp volume/gain? Listening to the in-ears, it seems the media volume is very loud even at low settings and amps up quickly with each keypress. Maybe there is another sound tweak I can make somewhere.

A common problem if you are also charging - you are setting up a ground loop. You can add a ground loop isolator on the audio cable (big and clunky), unplug the power, or unplug the audio (and use BT in its place).

While I'm not a die-hard audiophile (I won't spend 10K on a sound system) I do consider myself to be pretty selective. Partly why I ripped my CD collection @ 224 and not something lower - I did lots of tests beforehand and still could hear subtle differences @ 192. Also why I rarely buy 128 kbps mp3s. Anyway, for better or for worse I just don't hear anything negative so maybe yours is defective. I will bust out some in-ear buds tonight and take another listen.

Often media players will have a separate volume from the phone's "media volume". Then there are separate "media volume" settings for BT and the jack. Then don't forget internal volume on BT headphones. It can take some fiddling to find the best combination.

I had the same thing with all my devices. Its just bad ground. That cable will get you set straight.
I never listened to my note with headphones, just with my car stereo with that cable. I hear absolutely no hissing or whining noise, just absolute beautiful sound and bass. This phone is mounds better than the Captivate.
Well, I retried some EQ/volume apps that I might has used recently to make sure there isn't any overboost feature enabled but nothing I can do to solve my problem. argh...
I never tried headphones in my Note with the stock sound equalizer. I had already installed the Beats by Dre mod in the developer's forum.
Zero hum whatsoever, and my happy hardcore sounds amazing.
I too have hiss from the headphone jack. I just returned my first Note yesterday hoping that the hiss would go away. It did not. I use mine in the car with an adapter that hooks directly to the back of my radio (JVC proprietary style).

Huh... I was about to return mine today but maybe it might be fruitless? Or maybe there is a large quantity with hiss and others without?
For those with no hiss, do you find the volume to be very loud? What I'm talking about is even at low settings, just 2-3 notches above silent, the volume is already pretty loud. My phone feels like the internal "gain" was set too high.
I know on my captivate, I could set the media volume to about 40% and still be comfortable. On my Note, it's about 20-30% if that.
Does volume of the note sounds real low to you compared to smaller phones???

No, it is TOO LOUD. just a couple notches above zero and some music is already getting too loud. This is with headphones not internal speaker.
I just got back from swapping my phone from the AT&T store. Both models (black/white) on display had the hiss. I decided to go ahead and swap and maybe a new shipment had an updated phone. NOPE, the hiss is still there.
I've used 3 different in-ears (couldn't find any over the ear cans) and also tested on a captivate and galaxy tab 10.1. It's the Note that is doing the hissing and very noticeable even at low volumes. Easiest to hear is right when you track begins but before the music starts.
I think this might be a deal breaker for me. I love this thing though. Especially irritating with spotify between tracks.
music end -> hiss -> soundless gap -> hiss 0> music starts
Anyone know of an app (probably one that requires root) that can adjust the internal gain like what voodoo sound did?
This older thread I just found (post #5) seems to describe my problem as well.

In order to quantify if this is hardware or not, try doing a factory reset (since you've returned your phone it shouldnt be that big of a deal).
Then, using the stock player on the phone (feel free to update Google Music or any other apps that came with the phone) see if you have the same hiss.
The factory reset is to determine if its possibly an app you installed at some point that is 'boosting' the sound internally without your knowledge. Sound boosting can create signal to noise problems.
Make sure your phone isnt plugged in / charging to anything (not plugged into a PC for example).
And try moving around to different locations, for example, in your house, try going into your front / back yard and see if the problem persists.
You also might try a different set of headphones and see if you have the same issue.
And lastly, if you plug in the headphones and reboot the phone, once the phone is fully booted, check to see if you hear any hiss WITHOUT any apps open?
As a side note, I just tested this (believe it or not, Ive had the Note for 3 weeks now and never plugged in headphones) using Seinnheiser studio HD 600 headphones (very expensive at around $600 for a pair and VERY power efficient) and have no hiss. However, the sound quality isnt all that great but that is a different issue.

Thanks for your helpful tips. Unfortunately, I've tried all that. Factory reset and all. As soon as the phone is ready to go, I listen to some music and hear the hiss immediately. Home or office, no difference. Not plugged in. Different in-ears. 4 different Notes.
I'm using very good in-ears (UE 700s, dual armature) and also decent SuperFi.3s.
Something interesting. Took a listen to a friend's good headphones just now and do not hear any hiss. Even if the media volume cranked up close the max, sounded fine, no hiss and listenably loud. With the in-ears, I can barely get half way up in volume because it becomes too loud.
Anyone here use in-ears? I know most prefer headphones or earbuds.
I'm going to try an inline attenuator tonight to see if that helps (if I can find it!).
What do you mean 'as soon as the phone is ready to go'?
As in, the instant you plug in headphones the hiss is there?
My guess is likely that the in-ear headphones are putting the sound right up to your ear drum and they likely are super sensitive.
The sound chip in the Note is not near to as good as the sound chip in the Captivate.
Im going to do a bit more experimenting with this as the only headphone I have are the seinnheisers and they arent exactly great for portable listening. I have a friend coming over tonight who has some very high quality in-ear headphones and Ill see if I hear anything with those.

Bluetooth audio quality?

So.. I bought the DNA today and am severely regretting this decision.. Wondering if anyone has experienced the same issue?
I have a Jaybird BlueBuds X bluetooth headphones. Compared to a lot of others, they have an amazing sound quality.. at least they had an amazing sound quality. When they were connected to my Galaxy S3 (running CM10.1 in the interest of full disclosure), they sounded as if they were hard-wired - no distortion, no buzzing, perfect sound quality.
I paired them with my new DNA, hoping for the same audio quality (and then some, due to famed Beats Audio) and... didn't get it.
So the problem I'm running into here is that they now sound like a pair of cheap, 10$ bluetooth headphones - the sound is distorted, there is crackling noise in the background, the music sounds like as if it's 64 kbps - barely usable, very unpleasant. As soon as I pair it back to my old S3, the sound comes back to life.
I've read the forums and understand that the OTA pushed out an update with some bluetooth fix.. I have the OTA (got it that way), so my phone is already running the supposed sound fix.
Has anyone experienced same problem? Especially with higher-end BT headphones? (Jaybirds, Sennheissers etc) Really like the phone, have been an HTC fan since WinMo days, but I simply cannot tolerate this BT flaw... Does it have to do with the BT chip that DNA has, or is it the BT stack/driver on this one?
++> On a side note - sound quality over wire is great.. so this a bluetooth only issue. The issue (noise) is more pronounced on higher frequencies..
I don't have BT headphones, but do have a Sony Xplod CD deck in my wife's Honda & pairing any of my HTC phones via BT sounds so horrible. However, I did get the HTC Steroclip for my Sony Xplod CD deck without BT in my truck & it sounds great. What gives? Was wondering if it might be the same issue as with the headphones.
I am running Creative 350's with apt-x codec and they sound great. I would find a set of headphones with apt-x. You won't be disappointed.

Well, quite honestly, when i first started researching bt headphones for exercising there has not been a single pair that garnered the amount of positive reviews as the bluebuds.. plus they did sound amazing on s3. I did look for aptx - s3 uses it, but no workout headphones that had aptx had good reviews in terms of build quality etc.
I do wonder tho...
On dev.android under the about Android 4.2 JB it does mention that it got a new BT stack developed, replacing current BlueZ as well as updated low-latency audio.. maybe the new stack does indeed improve quality.
im going to flash the s3 with stock 4.1 and see how it sounds and then try a couple of variations of aosp stuff and report back..
Ps. I also found a mention of how s3 uses a2dp edr natively, whereas dna is using aptx... Its going to suck if this is truly a hardware issue...

I think Stereoclip has aptx.
So I flashed S3 back to Stock VRALF2, 4.0.x ICS, and played a couple of songs and still was getting crystal clear quality.. So it has to be the BT implementation in DNA.. Sad. Anyone has any insight into why/what could be the root cause? BT chip? DAC chip?
Thanks
If it helps any, Bluetooth audio sounds great in my 2012 Sonata.

Do you know if the radio in your Sonata supports aptX?
Shoot I'm not even sure what that is. It sounds pretty much the same as when I have it plugged in tho.

I use blue tooth in my car all the time and also over the blue tooth streamer for my receiver at home.
Sounds crystal clear and I have very nice speakers in both the car and at home.

Is codec support built into blutooth or can codecs be added/modified. If so its a non issue. I would help with codec support if I were rooted

Same issue. I streamed music from the same Google Music account, on both my Rezound and DNA, to the same receiver (2010 Infinity G37S).
DNA audio quality is noticeably bad. Especially in mid and high range. It sounds like very low bitrate audio, and/or very lossy compression. The Rezound audio quality over BT is nearly the same as wired.
I suspect HTC has deliberately chose to use a low bitpool value for A2DP w/ the stock Sense ROM. DNA now supports atpX. So, they gimped A2DP stream, with the goal being to sell more of their Bluetooth Stereo Clip product, that support atpX.

If that's really the case.. shame HTC. My m25 ear piece supports aptx and sounds great playing music. In one ear...

Jaybird + dna
I have a set of jaybird freedom's myself and have had no issues with bluetooth, beats audio or audio quality. One thing i have seen though is that some roms do not handle beats over bluetooth very well. The other thing you probably should look at is to make sure that it is pairing as a stereo audio device and not a mono audio device.
+1 for horrible quality here. I use these LG blue tooth ear buds and they just sound terrible. sounded fine on my gs3...and I used one of those jbl stereo boxes and it's awful.. and again fine on the gs3. sucks.

I have a set of Sony bt headphones (bought on amazon a while back for around $40 way before DNA I had Bionic back then) that sound very good I also stream via HTC BT dongle to my Sony xplod in car with with Fosgates all around music sounds GREAT I can really tell the difference when Beats is off even more so when I flash Awesome Beats...I also noticed a setting the other day on my Sony deck for AUX VOL while messing with sub output I turned the AUX volume up now I'm really bumping hahaha

DNA Sound Quality
I hope you haven't given up entirely on your DNA since your post because there are some options you can explore.
Did you try turning off "Beats Audio" in your settings? I purchased the Power Amp music player update and Power Amp and Beats Audio don't work well together. In my experience, the standard Music player that comes with your phone works best with Beats. Other music players may also have the same problem. Second question, did your problem go away with the latest update to Jelly Bean 4.2.2?
Good Luck,

So.. I bought the DNA today and am severely regretting this decision.. Wondering if anyone has experienced the same issue?
