Scratchy Sound with Gentoo

sendas4 · 01-24-2005, 11:50 AM

Im just installed Gentoo with 2.6.10-r6 kernel. i did a stage 3 and compiled the kernel myself. and opted for my sound to be automatic instead of module under the alsa pci section.
The everything sounds fine in windows. but everytihng is scratchy with linux at the moment.

Is it possible to have doen the wrong device but it would still produce
Alsamixer says
Card: NVidia nForce2
Chip: Realtek ALC650F
Item: Master

and this is what i get when i do lspci.

Code:

what sound modules are you actually using? show us the output of "lsmod" if you're not sure. I too have Nforce2 onboard sound, and i use the snd_i8x0 module under Alsa, and i'm currently listening to Master and Everyone by Bonnie Prince Billy in great great quality... you should be able to change to this module by editing /etc/modules.autoload.d/kernel-2.6

I dont have much running as modules. I have my sound built into the kernel. i currently have 2 sound modules built into the kernel

Intel/SiS/nVidia/AMD/ALi AC97 Controller

and

VIA 82C686A/B, 8233/8235 AC97 Controller

Code:

bash-2.05b# lsmod
Module                  Size  Used by
nvidia               3463580  12

eww nasty.... rebuld them as modules for a start... then ensure you're running ALSA, and not OSS.

sendas4 · 01-25-2005, 09:40 PM

Yup made sure im using ALSA. And i changed my kernel to handle the sound pci device as module. i get this now

Code:

bash-2.05b# lsmod
Module                  Size  Used by
nvidia               3463580  12 
snd_intel8x0           28576  0 
snd_ac97_codec         72224  1 snd_intel8x0

But the sound is still bad. Could there be a just totaly F'ed up setting i could change with amixer?

Although i'm not using gentoo I have the same problem with slackware. I'm pretty sure it's because in alsamixer it says my chip is "ICEnsemble ICE1232" when it should be a ac97. Sound works but is scratchy... I think i just need to know how to change the chip?
