Hi,
I've read all the docs I can find, compiled and installed alsa as
instructed.
Everything *appears* to run successfully, but.....
ALSA runs, inserts modules and creates device files but then can't use them.
I feel I must be missing something really simple, but can't for the life
of me find it.
Here's output of a couple of utils (I've tried both as root and regular
user):
alsamixer
ALSA lib control.c:816:(snd_ctl_open_noupdate) Invalid CTL default
alsamixer: function snd_ctl_open failed for default: No such file or
directory
alsamixer -c0
ALSA lib control.c:816:(snd_ctl_open_noupdate) Invalid CTL hw:0
alsamixer: function snd_ctl_open failed for hw:0: No such file or directory
aplay -L
(no results)
aplay -l
**** List of PLAYBACK Hardware Devices ****
ALSA lib control.c:816:(snd_ctl_open_noupdate) Invalid CTL hw:0
aplay: device_list:231: control open (0): No such file or directory
The kernel documentation at
(/usr/src/linux-2.6.19/Documentation/sound/alsa/ALSA-Configuration.txt)
contains the following, which would seem to mean that it supports my setup:
" Module snd-hda-intel
--------------------
Module for Intel HD Audio (ICH6, ICH6M, ESB2, ICH7, ICH8),"
and
" STAC9227/9228/9229/927x"
I've included what seems to me to be relevant system info below. Please
let me know if anything else is needed.
Really, really, *really* would appreciate any help I can get.
Thanks,
Ed
