Hello,
I've made several posts to this list on related
problems which all seem to have the same source;
unfortunately I have yet to receive any reply. Please,
please help if you can; I'd be eternally grateful for
any practical help/suggestions.
I am running SuSe 7.0 on an i686 with a 2.2.16 kernel.
I have a VIA 686a sound chip on the motherboard. I
obtained the alsa.rpm and alsaiconf.rpm from the v7.0
section of the SuSe ftp server. I also downloaded and
built the latest stable alsa drivers, utils and libs
from the alsa project web site.
I set my system up for alsa using the alsaconf
utility. Installing alsa from the alsa web site doesnt
make any difference.
I understand that I am supposed to unmute the mixer by
use of the amixer command, however I consistently get
nova:/proc/asound # amixer info
amixer: Mixer 0/0 open error: Invalid argument
[same result whatever parameters are used; similar
result for alsactl]
Examining the source code reveals that this is due to
a failed ioctl call i.e. the mixer device has been
opened, but ioctl() failed subsequently.
Examining /proc/asound gives
nova:/proc/asound # cat cards
0 [card1 ]: VIA686A - VIA 82C686A
VIA 82C686A at 0xdc00, irq 5
and I provide lots of information below. I am very
sure the VIA chip is not PnP. Interestingly, after
carefully rmmod'ing all dependent modules, I am not
able to rmmod snd or rmmod soundcore because I am told
'Device or resource busy'. The docs under
/usr/src/linux-2.2.16.SuSe/Documentation/sound tell me
to RTFM and check if any other process is using the
sound device. However I do not run Enlightenment or
gnome, (I run fvwm2), and I fail to see what other
process could be hogging sound.
Could someone please please help? I've been banging my
head against a brick wall for far too long. Why does
sound installation have to be so hard?
Thankyou
Andrew Scott
