[SOLVED] Garbled and Scratchy Audio

daedalus · 2008-08-30 17:57:01

Hey all -

I am having a pretty frustrating problem with my audio, and can't seem to find any fixes or locate any threads that duplicate my problem online.

Firstly, the audio is always scratchy. If there is no audio being played, the speakers are silent. But as soon as there is some sort of audio output, they start making a scratching noise.

Secondly, audio from embedded Flash videos (youtube, for instance) is horribly garbled. It sounds like the audio is reverberating through an AC vent, being shifted in pitch, echoed, and then output. Interestingly enough, this doesn't always happen. After a fresh restart, it is fine for a bit before turning into a garbled mess again.

I have the Intel 82801I ICH9 HD Audio Controller, as shown by 'lspci':

00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 02)

and have the correct kernel modules loading:

snd_hda_intel         357048  7 
snd_hwdep               8964  1 snd_hda_intel
snd_pcm_oss            40192  0 
snd_pcm                69636  4 snd_hda_intel,snd_pcm_oss

None of my ALSA settings are in the red, and the PCM setting is at about ~50%.

I know the issue isn't the speakers, since the machine is a dual-boot with Winblows, and they work fine there.

Can anyone help?

try using OSS (http://wiki.archlinux.org/index.php/OSS); it works fine with my Intel HDA audio chipset

if you want to try staying with alsa, try editing /etc/modprobe.conf and adding:

options snd-hda-intel model=lenovo

you have to restart to make it take effect. there are several options you can try instead of lenovo, try the alsa page for Intel HDA
