speakers popping with new 2.6.30 or pulseaudio

mps2006 · #1 8th September 2009, 02:38 PM

Hi

I just ran an update which included both the new kernel 2.6.30.5-43.fc11.x86_64 and pulseaudio 0.9.15-17.fc11 . I now get random popping sounds from my speakers (on a Dell E6500 laptop).

Any ideas which would be causing this or how to work around?

Thanks
M.

try booting with the old kernel version and see if the problem is still there. if it is then is most likely the pulseaudio update is crap.

I can confirm this issue also with my Dell Inspiron 1545 running Fedora 11 x86_64.

After updating to kernel-2.6.30.5-43.fc11.x86_64 I also have this issue during boot and even after logged in.

Confirmed here as well...popping does not happen with previous kernel. Super annoying, and neither plugging in headphones nor muting sound makes it go away.

Using:
Dell E6400 laptop
KDE 4.3.1
Linux xxxxx 2.6.30.5-43.fc11.x86_64 #1 SMP Thu Aug 27 21:39:52 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux

I've noticed popping and on one of my computers, the volume output is much quieter, even when all of the alsa and pulse volume controls are turned up to the max. It's a bit annoying because now I can hear the speaker hiss.

the 2.6.30 kernel is crap. probably the kernel team is made-up of amateurs. try booting with an older version or switch to a stable distro

Those seem a bit extreme, as solutions go. If you don't want to weather pulseaudio development, get rid of it and use alsa or ossv4.

I can attest to everyone above, it is not limited to Dells. My HP DV6000t CTO laptop is having the same problem: Random popping and slightly quieter volume. It seems to be happening right after login, and after that it is purely random... Also, I tried using headphones, muting, etc. It is a bad combo of a bugged package and a somewhat poorly integrated upgrade. Chances are though, that it is a simple fix.

I live right near Paul Frields (Fedora Project Director), and will see him in a week, maybe he has something so add, good or bad.

I was having a problem like this when I updated to the 2.6.30 kernel. See this bug report - there are some temporary workarounds for now:

WOW, go figure. The suggestion described in the link above, says that by disabling power-saving on Intel based systems (laptops primarily) the weird noises go away. Though not a fix, it is a doable patch in the mean time.

I have personally tried the patch and have not had the popping since since (all of 5 hours).

Here is a how to that improves Pulseaudio. http://forums.fedoraforum.org/showthread.php?t=225660
May improve things for you.

EVEN MORE IMPRESSIVE! I can't wait to try this 'fix'. It is very thorough, so I don't expect any problems, but I will wait until morning local time to make the necessary fixes. I was actually at the point of just waiting for ALSA to be revamped in Fedora 12, but this is probably a better solution in the mean time.

Thanks ozjd so much for that link!

P.S. Do you do any audio production/editing via Fedora or just *nix in general?
