[Q] Sound crackling/popping using certain roms/kernels?

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.

[Q] Speakerphone/Earpiece Quiet after CWM

HI All,
I've noticed for some time now that before I flash a new ROM, when I go back to stock JF6 the audio in the boot up screen will blow your doors off. After flashing CWM, the audio is there but it is must less pronounced. I've also noticed that while using the speakerphone or the earpiece during regular calls, I struggle to hear the caller on the other end. It's fine before I flash CWM.
Anyone run into this before and if so, what can be done about it?
Thanks in advance!
Dan

I too have been wondering about the volume. I thought it was the rom I was running. I'm currently on phoenix 4.5 with firebird 2 v0.7 kernel. It seems like my volume is lower when I call another cell but fine if I call a land line.

i noticed this too. i use speakerphone alot, and it IS quieter now i use custom roms, and i use speakerphone MORE NOW because the earpeice is hard to hear.

Fix for Low Ear Peice abd Speaker Volume
I am not a programmer but I was wondering with all the talent on this site why is it impossible to have a fix for the terrible in-call volume the Captivate has. I have tried the settings in the service menus, but havent seen anything worth while.
Non of those settings stay past a reboot anyway.
The phones hardware is able to output the louder sound, I dont understand why we cant fix the low in-call volume on the earpeice and the speaker phone?
HELP!!!!!!

this post beat you by a few hours and is a little more specific/accurately worded (your post isnt a fix)

Thread merged with a similar one. I think the poster above U is asking a question (interrogative icon) and not stating he is posting a fix.
Cheers,

I noticed that it's CWM that is killing the audio (for me at least) before I flash a new ROM.

[Q] In call volume and dial tone very loud and harsh after flashing

I have been using darky's rom since about 5.4 and I flashed 9.2 and couple of weeks ago. One annoying change is the handset volume has increased and the clarity of the dial tone and in-call is very harsh and 'crackly'.
I have tried flashing over different customs roms, reverting back to stock roms and even tested out cm7 while i was at it with no luck at restoring the previous clear, softer dial tone and volume.
I have also tried this to no avail:

Any suggestions??

try to wipe yr phone totally internal sd and external and the flash rom again,

So i've tried formatting the internal sd. After I flash back to standard firmware and also darky's 9.2, I still have the same problem.
Any other suggestions?

Could be a modem problem. Maybe your modem is not meant for your region.

So i just tried the standard jp5/jp3 standard rom for optus/virgin and still no good. I only get clear audio on the lowerst or 2nd lowest volume setting and anything above makes it sound like the speaker is vibrating

Ended up being a hardware issue. Samsung were able to fix it. Not sure if they replaced the speaker or not but its back to normal now
Thanks guys

[Q] Earpiece sound level very low

Hey, I've been having issues with the sound level from my Nexus One earpiece lately. I'm currently running CM 7.0.3. I was having the issue as well with an older build, can't remember the version number. Did a complete wipe including cache when I upgraded to this build. I have also tried replacing the actual earpiece with one I purchased from eBay, no change. The volume level is so low that I have to have nearly complete silence around me to be able to carry on with a phone call. That or use a headset/speakerphone.
Anyone have any suggestions for what else I can try?

Have you tried changing ROMs to see what it sounds like on other ROMs also you could always try flashing a kernel with an audio boost.

[Q] Call Quality with Alternative CM10 Kernels

I am a long-time user of CyanogenMod, but I have never flashed a non-"stock" kernel into CM until recently. I tried the Devil and Semaphore Kernels, and while performance was excellent, my Captivate's speaker is problematic with both of them.
First, the speaker is extremely loud regardless of how low I set the volume. This volume issue does not appear when the speaker is disabled.
Second, when I activate the speaker, the person with whom I am speaking complains that I sound "distant and tinny," possibly with a lot of reverberations. This is not the other person's hearing him- or herself. If I disable the speaker, regardless of whether I actually move the phone toward my head, the problem seems to disappear. They can hear me clearly.
Re-flashing CM10 fixes both problems. I have not modified the default settings introduced by either non-stock kernel. Could these issues be due to audio tweaks introduced in those kernels? Does anyone have any suggestions for me if I would like to continue using one of them?
Thank you!
