So I've discovered a pretty nasty bug that seriously affects my listening pleasure.
I should start by saying that I am a recent Android convert, the GN beeing my first foray into the realm of Android devices.
Having used an iPhone for the past 3 years (and mostly for rocking out to my favourite music on my daily commute) I was initially really excited with the quality of the audio on the GN, even when using the stock iPhone earbuds. This issue however, has nothing to do with the earphones, it happens even when the phones are disconnected
I noticed however that my music had a tendency to start clipping (clicking horribly while playing HQ files in most supported formats). My first step was to download pretty much every decent player I could find - right now, I have WinAmp and PowerAmp installed.
I eventually narrowed the problem down to the lock screen, more specifically when the screen blacks out after being idle for nn minutes. s
o long story short, if I play my music with the phone unlocked it all sounds really good, as soon as I lock the screen (clicking the power button at top right to switch to black screen) the music starts clipping horribly at very irregular intervals.
I've asked a mate to try the same steps on is GN and he says he can't hear any difference, so wanted to put this to the community to see if anyone else has experienced anything similar. Does this sound like a return job?
Being an android noob, I have no idea of any methods of providing debug info, so any input is welcome.
Thanks

i think all android phones do this...... at least my desire did this as well. Thats if you mean a very slight break when the screen goes black ?

I have not experienced this on my Nexus S and I listen to music a lot with my screen locked.

Its just one fraction of a second blip as the screen locks in my experience.....
NO, in my case it's constant, like every few seconds... sounds like a case for replacement imo

Ya that's not a usual problem. Sounds defective. What file types are the music?

when the screen is locked on any Android phone, the CPU is underclocked to save power.
what you're experiencing is audio buffer underruns due to the CPU slowing down. this is normal.
have you tried playing the music using the default music player? you shouldn't experience the problem using the default music player.
Try changing the encoding of your music. The phone is probably struggling to decode your current format in the underclocked state.

I know where you are coming from but I don't experience this issue on my GN.
Go to power amp. Settings, audio engine, advanced tweaks and set the buffer to huge. I don't think it will work as it seems to me its when your device goes into sleep. Like the CPU is being undervolted too much. If it happens on the stock music app (Google music) I would send it back as defective.
OR - Maybe Google don't want you to use ****ty iPhone headphones after all.

it is more likely going to be related to the third party apps he is using to listen to music, that don't know how to keep the CPU alive in a higher state while the screen is locked. I had the same problem on my Nexus S with Skype for a while, where I couldn't actually put the screen to sleep using the power button while in a call - the audio would buffer underrun like crazy. Skype eventually pushed an update and it fixed the problem.

I was thinking the same. My GS2 had the same issue with power amp. But the stock app was fine. Crazy android phones but we love ya.

Not related to the ****ty iPhone headphones (lol thanks for that Nat) or the 3rd party apps I'm afraid... the same issue happens when I use the built in speaker, the GN issued earphones, and also regardless of whether I use the default music app or poweramp/winamp.
Changing the encoding of my music is going to be an extensive task if I have to do this for my entire library (30K+ tunes) I'll be here til next year.

what format is your music in, what sample rate and bit depth is it?
ie: FLAC 24bit / 192KHz
not sure oscillik, a range of formats (mainly MP3, some AAC) and bitrates (nothing less than 192k and mostly 320k) again not sure of the samplerate either, would have to check my library which I have no access to for now as I'm on the road

those formats and bit rates should be just fine. just to let you know, bitdepth and bit rate (emphasis on the space also) are completely different things. i think it's safe to assume that the sample rate for your music is likely to be 44.1KHz (which is standard).
you may have a faulty handset, I would demonstrate the problem to the store you bought it from and get a replacement handset.
I get the clipping too but only with Power amp and not the stock player.
Never had this on any phone before.
Might have to get rid! Anyone want to buy a GN 2 days old?

@spewy check NatTheCats post about settings in power amp, they did the trick on my device and strangely enough I'm no longer having the problem in the default player either. Thanks to Oscillix and Nat for your help.

Hello, does anyone experience a popping sound when they listen to music or watch videos? It's been happening to me quite frequently, and it seems to happen quite randomly. It also seems to 'pop' when i press the volume down or volume up buttons while watching a video or listening to music.
Anyone else experiencing this? I've determined it's not a problem with the video since I don't get any popping sound when I watch the exact same video on my laptop, and the popping sound doesn't happen at a fixed interval or anything. It also isn't a problem with my earphones as I've tried using the one supplied by HTC as well.
Any help please?
From memory I had this when playing around with dsp manager

I've had this once while browsing YouTube, don't know what caused it but it was annoying.
I rebooted my phone and its not happened since
Sent from my HTC One X using Tapatalk 2
All the time. I've got a Desire S with Sense 3.5 and that pop's as well.
Wow okay that sucks. Shall try turning off Beats Audio to see if it changes things. Or could it be an inherent HTC problem? Hmm.
Hi guys,
Is anyone experience an intermittent audio stutter on the YouTube app. I was watching some YouTube videos this morning and there was no issue, however just 5 minutes ago I fired up YouTube and on every video I view every 30 seconds to 2 minutes the audio will stop for less then a second then continue.
Really annoying, sound off if you have it guts. It seems be be intermittent.

I've had this problem too but its fine at the moment running the latest LeeDroid rom.
I've had this bug happening to me as well. The problem is exaggerated when using some kind of EQ or DSP app/ widget.
What really annoys me is the loud pop whenever the audio chip is being turned on/ off. This can be heard (especially well with headphones) in every app that plays sound.
had the same problem on stock, very annoying...
Found that reinstalling flash solved it.
Now running charmeleon 5.0, no stutter.
Hope it helps
Have the same problem on stock! Have to reboot in order to get it fixed

Yep. I have it too. Latest Vodafone branded stock. Youtube app stutters and pops like crazy. When I play the same video through the browser it doesn't though.
Hello there,
I've lately experienced some trouble whilst listening to music. I'm using Poweramp music player on my LG P940.
It would work normally until at some point I wouldn't be able to hear anything although it says the music's still playing and the volume is at maximum. Turning up and down the volume, pausing and playing the music and unplugging and replugging the earphones would not help. Some minutes/hours/days later (different every time) it would work normal again. Has anyone ever had this problem before or has any idea how to solve it? (I know that this already is posted in a different thread but I ain't allowed yet to post something in there).

I've been experiencing this for a while now, every now and then when I'd watch movies on my tablet using the stock video player or even others such as MX Player and VLC, a crackling sound comes off that it sounds muzzled and blurry at the same time and the only thing to resolve it is to pause the movie or video then resume It right away then it's gone. The issue is it comes back time to time but rarely happens on YouTube as I recall, now I'm not sure if this is a hardware issue with the speakers, I'm not rooted and haven't modified anything at all, I've had this tablet for 2 months. Anyone else experiencing this issue? I wouldn't want to trade this is for a brand new device but if I really need to I would. Was just thinking if there was a work around for this without rooting the device.

Can you record the sound? Might be the app and the video itself if everything is fine on youtube. For my device I use allstar video player and its all fine. Could be an app issue with the video maybe? I havent tryed those video player apps but stock is fine for me also.
Not sure, thanks for the reply though. I could try recording it. Maybe it's just my speakers, cause I usually use the stock video player for my movies and that's where it happens.
