Sound problems are driving me absolutely insane

roarkh

I am trying to get audio drivers working with my new Gentoo install. I have an MSI K8T Neo motherboard and an Athlon64 3200 processor. So far everything seems to be working fairly well but I can not get audio to work. A run of lspci reveals the following information about my sound controller...

This is why I hate modules. Try

The module is definitely being built.

When I try

Looks like you might need snd_ac97_codec... dunno where that's built. Do you have the module?

Well I recompiled my kernel but this time did not compile the alsa stuff as modules. Now things are somewhat better. XMMS will now play stuff but periodically the song will skip or sound very strange (almost like it is coming from under water).

Thanks for the suggestions.

I personally think modules are real handy, don't have to re-compile the whole kernel, reboot etc., but that's besides the point.

The oss module works for the via chipset, so you could give that a shot. Xmms does skip for me if the computer is under load. I guess you could renice xmms, that might give you better results, but I just plug in my laptop and listen to that while somthing's compiling.

Did you run modules-update to make /etc/modules.conf current?

For the underwater warbling, try muting 3d output in alsamixer.

Well I seem to have sound working pretty well now. I recompiled my kernel again with snd_via82xx compiled as a module and for some reason things are working better this time.

The sound quality problems I was having appear to come from the fact that this sound card will only output at 48000khz while xmms was attempting to output sound at 44100khz. I unmasked and installed the xmms-crossfade package and set it up to resample at 48000khz and sound from xmms is very good now.

I found this website which helped quite a bit, http://alsa.opensrc.org/index.php?page=via8233.

Setting dxs_support=1 works best for me, here is part of my "alsa" configuration file in /etc/modules.d

I have the same MSI K8T Neo motherboard and I can't get alsa working in xmms. I'm using the 2.6.3-gentoo-r2 kernel and have compiled alsa into the kernel. I do get sound, but only when using the oss-emulation. When trying the alsa output plugin I just get 'broken pipe'. The crossfade plugin doesn't seem to do much good either. Should I use /dev/sound/dsp or /dev/sound/adsp? My alsa conf is:

Have you compiled the audio drivers into the kernel or as modules? I don't know if this will help but this is exactly how I have set things up in my kernel config.

if you compile sound into the kernel insteadof as a module do you still need to configure /etc/moudles.d/alsa? How do you configure alsa if you don't need to edit this?

Also how do you get the snd_codec_97 to work? Is it a kernel compile option that can be compiled into the kernel or as a module?

thanks

Thanks roarkh! I have the same motherboard and had the same problems. Sound has been working for 2 minutes now. That's 2 more minutes than it has in the past week.

Gentoo 64 bit is great! WinXP 64 sucks big time!
