Take it easy, since you have reasonable /var/log/messages stuff maybe you are
not far off. I can see two things I might have expected in your list but
didn't see.
First, cat /proc/asound/cards and see what Alsa thinks you have.
$ cat /proc/asound/cards
0 [I82801BAICH2 ]: ICH - Intel 82801BA-ICH2
Intel 82801BA-ICH2 at 0xe800, irq 9
Next, have a look and see if you have alsamixer in your path, if not
install
$ rpm -qa|grep alsa
alsa-lib-devel-1.0.4-1
alsa-utils-1.0.3-1
alsa-lib-1.0.4-1
$ which alsamixer
/usr/bin/alsamixer
Then run alsamixer (the gold standard for alsa volume control) and
see what
you see. Note that many mixer chips have a bit to control the power to an
external audio amplifier, if this is set to power the amp off you will get no
output.
Thanks, you've saved me a slow terrible suicide...
I tried alsamixer some time ago and got somekind of error and it
didn't run. I don't think I've tried it since. That was all I
needed.
Took a little mucking around to figure out what stuff did what.
Only remaining thing I see wrong is that the output isn't near as
clear and staticless as it is when these speakers and sound card are
used on a windows xp machine. They are just junkyard powered
computer speakers but sound ok when connected to a different
machine. So must be the signal coming to them is different somehow.
