Debian Lenny Sound - very low volume


I have an odd problem with sound in Deb Lenny. The sound works for all apps I have tested, but the volume is so low that it's barely audible. I have adjusted levels in kmix (I'm using KDE), but this doesn't help much. It seems that a lot of the sliders and switches are missing from kmix, as compared to Fedora 8, which also runs PCM sound.

I'm running a Toshiba A100 laptop with built-in Intel sound. from /proc/modules, I think these are the relevant drivers:

d00k:/proc# cat modules | grep snd
snd_hda_intel 239160 5 - Live 0xf8ac1000
snd_pcm_oss 39200 0 - Live 0xf8a72000
snd_mixer_oss 15424 1 snd_pcm_oss, Live 0xf8a14000
snd_pcm 72324 3 snd_hda_intel,snd_pcm_oss, Live 0xf8a5f000
snd_timer 21028 2 snd_pcm, Live 0xf8a1d000
snd 48324 13 snd_hda_intel,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer, Live 0xf8a24000
soundcore 7520 1 snd, Live 0xf8a11000
snd_page_alloc 10056 2 snd_hda_intel,snd_pcm, Live 0xf89c0000

I would graciously appreciate any enlightment that might be shed on this odd problem. Maybe I'm just "doing something dum", but I haven't been able to find it yet.

Thanks,

Galen Overstreet

Have you checked the levels with "alsamixer"?

Excellent idea. The master vol seems stuck at "00". I cannot seem to adjust it. I tried it in Fedora just to be sure, and can easily adjust it.

Perhaps this is a bug....after all this is the "testing" branch.

Thanks so much for your valuable suggestion!

I suppose you've already ran alsaconf, part of the alsa-utils package.
Do you have a ~/.asoundrc ?

No, do not have ~/.asoundrc.

BTW....according to alsaconf, my sound chip is:

Chip: Realtek ALC861

Thanks Again,

Oh well, your card probably has a bug in the alsa version shipped with etch'es kernel.
This could shed some light: http://www.mail-archive.com/search?l...Realtek+ALC861
Especially this: http://thread.gmane.org/gmane.linux....74/focus=41309
If you have the kernel source, look in /path/to/kernelsource/sound/pci/hda/patch_realtek.c

Edit: You might as well grab a newer kernel source from kernel.org and roll it yourself to see if the newer ones include the patch.

Thanks. I was thinking about that.....haven't compiled a kernel in a long time.
