It seems that when i play music/video via either the headphones or loudspeaker I experience crackling and/or popping usually a few seconds into the song or video.
The weird thing is that only certain kernels do this. For example, my stock rogers ROM does not do this, nor does the stock AT&T ROM. But the minute a load up a cutoms kernel(usually a Voodoo lagfix based one) then this issue begins.
The culprits are the firebird and the glitterballs kernels. When I use the speedmod and suckerpunch kernels, my sound is perfect crystal clear.
Also I have done some searching everywhere and found other people have had this issue and by disabling WIFI this goes away... :S I can confirm this as it does indeed solve the sound crackling issue. And yes I have tried matching different modems and kernels to make sure that wasnt the problem and still nothing.
So please if maybe any of the devs or elite members could help me figure out what the issue is. Or even if you experience this too or just havent really noticed?
Thank you and I will buy a beer for anyone who can help me solve this. Yes, thats how annoyed I am at this issue.....
anyone? possibly canadian captivate owners experiencing this?
Experienced the same thing too. Even tried different music players. Turning off wifi stops the crackling/popping.
I'd really like to find out why only the voodoo lagfix kernels do this. Perhaps a way the ext4 code is implemented. But its strange because cog 3.04 doesn't and it uses voodoo lagfix.

Jp6 + Voodoo or Jp6 with OCLF has the same symptoms. Makes me think it's JP6 that is causing this.
The default music player occasionally stutters while playing MP3 Files (converted with LAME, V0). It happens a few times a day at least. I don't remember that happening in JM6, JM8 (very sure), or JPM(only tried for a day, not sure).
By stuttering I mean that the music is stuttering, not the UI. I've got over 16GB of songs, so the UI definitely lags if you try to scroll too fast on all firmwares.
The stutter is like the kind you get from CD players in the 90s if you shake them too much. Just for a moment.
Anyone else noticed this?
Count me in bro. The music list also stutters when I scroll down. I have 1.4k songs by the way (still have 5gb free still).
Same here. BT and jack. I've uninstalled one suspect: Days. But it could also be caused by kswapd0. JM5 'jittered' sometimes on the jack, but never on BT. And that sounded different, like it was missing cpu cycles. I'm still monitoring what's going on...
my music has been stuttering since day one. lag fix or not. dug up my old iPod and I'm happy now.
Ive never had music shutter. Maybe you sonegow have defective phone?

Running JP6 without a lag fix. Didn't notice it.
But then again I haven't used it a lot after the update nor have a very large song collection (only about 150~200 songs).
If you mean the music sometimes stutters, then yeah I have that too. I had assumed it was something wrong with the bluetooth connection (I use bluetooth headphones) but it might well not be...
Happened for me in all firmwares, solution was to use a different music player.
Might I suggest http://www.cyrket.com/p/android/com.tbig.playerpro/ ?
If this is flac, then it's a known problem since forever. I had hoped that they fixed it in 2.2, but maybe they just made it worse Is this a regression those with the problem?

If for any reason kswapd0 kicks in this means the phone is running low on free memory and starts swapping. kswapd0 is rarely ever (never?) the direct cause, it's just trying to manage the memory. Or lack thereof
hi guys. I also have this problem. I've tried ALL firmware jm8, jm9 and so on. I also tried froyo 2.2 official via kies, and it do the same stuttering problem, but much less. I don' know how to solve this problem, infact i also tried all of media player. Help me guys
Use to have this issue with my flac files, but since JPK i've had 0 issues. I'm on JP6.
I'll confirm this today

Interesting! Another reason to upgrade to 2.2
Just need a stable voodoo first
Personally. I have tested for 2 or 3 days the official 2.2. froyo. This problem ALWAYS HAPPEN, but seems much, MUCH LESS, but SOMETIMES HAPPENS.
So i start to think that is a real problem this....Someone could help? it could be the oneclick fix laga that i installed?
I think there may be a little misunderstanding in some posts.. By stuttering I mean that the music is stuttering, not the UI. I've got over 16GB of songs, so the UI definitely lags if you try to scroll too fast on all firmwares.
Yea same thing, i mean micro 1/10 sec stutter. Mine are gone though... just tested today although they weren't FLAC files. I'll have to restest with FLAC.
Didn't have any lagfix installed when it stuttered so i don't think it's that
I've noticed this in video playback. Was buttery smooth on 2.1 firmwares, but it now stutters when there is... dunno how to explain it, but it's related to sound. When some music kicks in, or there is a laughter track.
Edit: Currently using JPM, had same problems on JPK too
I'm going to try JPM again.. and hopefully find out tomorrow that it doesn't stutter. =D

Hello All,
I searched first by the way :-/
Recently my Nexus has had its earpiece too loud for both Incoming and Outgoing Calls.
At first I thought it had something to do with the radio, so I downgraded. It actually worked on the first call but after that it was loud as heck even on the lowest volume.
I tried to retrace my steps with my applications next, but nothing that would point to the earpiece. The last apps installed updated where mostly games like Fruit Ninja and Aliens vs. Humans, so I think we can rule out that.
The specs in my sig should be up to date.
The only variable that has changed other than the ones listed above is the fact that I recently bought a Jawbone Icon Bluetooth Headset. But to my memory, this issue began before that.
Can't find a solution anywhere cause it seems most people have an issue with the phone being too soft lol.
I'm really looking for some help guys. I'm just short of wiping the phone clean and reinstalling CM6 and my apps. If that dosen't work I'll have to use the warranty I guess. Had the phone from about Sept 10 I believe.
Let me know if I missed anything guys. All ideas are welcomed to fix this issue.
It's probably because of CM. CM uses a audio boost kernel by default, so I'm guessing that's the problem. Try installing no audio boost kernel to see if it solves the issue.
yeah if you are using cyanogen ROM, they added an audio boost hack long ago. on cyan 5.0.8 the audio boost was so loud that over 50% volume started to distort the speaker and kill your ears. so in later releases they split the difference and lowered it somewhat.
but the boost has always been there. the only likely possibility is that you recently started enabling DSP settings like compression or the EQ, which would suddenly now make things way louder.
Wow thanks guys. Had no clue that CM had an audio boosted kernel. Guess I'll be flashing something else for the while. Something as close to vanilla I guess.
Oh, I also checked the DSP settings, everything was off but was worth a shot.
Thanks again for the replies!
Just to let anyone with the same issue know, I found away around it. I installed one of Wildmonks kernels without the audio fix.
Kernel 2.6.35.10 to be exact. I get to keep my cyan features and have a decent volume ear piece too. Yay!
Good work. It's funny cause most people complain this phone is too quiet. If only they see this post!
My wife has a SGS on Orange UK running 2.2.1. For the last few months, the microphone doesn't work all the time during calls. Installing 2.2.1 didn't cure things as the issue has returned. I've done a factory reset as I hoped this might cure the issue but it didn't. Doing a bit of research has led to me here and I've successfully (I think) flashed the kernel to speedmod K13E using Odin as this looked like it might fix microphone issues. Unfortunately it hasn't worked. There is still no outgoing audio during telephone conversation unless shouting like Dom Joly and none on video unless speaking directly into the mic and even then it is incredibly faint. Does anyone have any more suggestions?
Thanks.
I am finding that no matter which version of Cyanogen's mod I use, either the official release, or one of the variants, they all have a similar issue:
When using my A2DP head set, all notifications and alarms will only play over the headset as long as it is connected. I have selected in the Cyanogenmod settings to force all notifications, ring tones, alarms over the speaker, but it does not seem to apply to A2DP.
Does anyone have similar issues, and has anyone found a solution if they have experienced this issue?
John
I can't be the only one having this issue. Its not there in stock and not there in MIUI.
I so much prefer Cyanogen roms though, minus this one issue. The ringtone also gets played over the bluetooth.
Its not an issue of turn off your bluetooth before you go to bed. Its also an issue of I can't hear my phone ring unless my bluetooth is on me.
Idiot, wrong section....
I see. Well thanks for the constructive post then.
And you're saying this behavior does not happen on stock roms, only cyanogen?

That is correct. Stock roms and MIUI roms do not exhibit this behavior for me.
that's a tough one. it will be hard to get the team to recognize and look to fix this discrepency. i had a similar "complaint" and i tried to go thru the code myself to see about fixing it. but your issue is way above my skill level so i dont knwo what you could do.
So I have been trying many of the latest Gingerbread roms as I had been with Froyo and Eclair. Recently, I went from Cog5v1 over to a CM7/MIUI rom and noticed that the headphone icon was always in the notification bar and I had no sound from the speakers. The internal speaker seemed to work properly, as I could hear ringtones, notifications, volume rocker, etc...but no system sounds, music and such. Also, when I receive a call, i cannot hear anything until i hit the spekerphone button and then the speaker works. Additionally, while on MIUI, I switched kernals and the problem inverted, meaning the speaker worked as it should but I had no headphone response at all. Since this problem occurred, I have flashed back to stock, master cleared, flashed froyo, flashed stock GB, and many others always flashing to stock in between. Now with every rom I flash I have the constant "headphone on" problem. Others have suggested hardware, but the speaker does work (speakerphone and when I change kernals and invert the problem), so im thinking it is more likely software, firmware, or bootloader related.
Has anyone experienced something like this before or could suggest something to try to fix the problem? I use headphones for music and audiobooks everyday, but if the phone cannot handle regular phonecalls, its pretty much useless to me.
First, Bootloaders and firmware ARE software listing them separately is just redundant.
just because the speaker works does not mean it's not hardware related. Sounds like an issue in the headphone jack. Try and spray it out with some air duster perhaps?
