Crackling sound in 10.04 with any sound card

Asked by Laurent Raufaste on 2010-05-11

Hi,

I juste installed a stock Ubuntu 10.04 amd64 but I keep getting crackling sound.
It's really light crackling but it's really annoying and it's happening on the two sound cards on my PC:

laurent@popol:~$ cat /proc/asound/cards
 0 [NVidia ]: HDA-Intel - HDA NVidia
                      HDA NVidia at 0xfe024000 irq 23
 1 [Xmod ]: USB-Audio - Creative Xmod
                      Creative Technology Ltd Creative Xmod at usb-0000:00:0b.0-6, full speed

Any way to stop the cracklings ?

Thanks

Please proceed with this page and in case upgrade Alsa, thanks.

The post is originally for the previous version of Ubuntu but someone on Ubuntu Forums seems to have solved a similar problem so perhaps it's worth taking a look:

I did not do all that was described, because I get sound, it's just souding crackly at times.

Here is the output of the alsa-info.sh script:

Lib and driver version differ. I'd say upgrade Alsa as suggested by troubleshooting page.

Since I'm not an expert, I assume you need to disable either one of recognized soundcards, e.g. using only the one onboard.
!!Soundcards recognised by ALSA

Laurent Raufaste (analogue) said : #5

You are right, but I have the stock 10.04 kernel and the updated 10.04 alsa packages.

I'll try disabling the unused cards

Laurent Raufaste (analogue) said : #6

Disabling the others soundcards didn't fix the the cracklings =(

Sam_ (and-sam) said : #7

Do you still have this driver:
> Driver version: 1.0.21

or this one:
http://monespaceperso.org/blog-en/2010/05/02/upgrade-alsa-1-0-23-on-ubuntu-lucid-lynx-10-04/

You may also try to add module options, which can be found in section '!!All Loaded Modules' from Alsa output above.

Laurent Raufaste (analogue) said : #8

This is not an ALSA problem. I just removed pulseaudio from my system and the sound is finally normal.

But it's a hack, there should be an easy way for all of us owning ok sound cards with hardware mixing to disable pulseaudio.

Can you help with this problem?
