Subject: soundcard problems

Hi Jesse

I have read your postings to various mailing lists regarding problems 
with your intel8x0 card og "semaphore" messages in /var/log/messages. 

If you have solved the problem, please tell me. Otherwise I want to 
share my experience.

I am configuring a brand new laptop (Asus M3000NP) with the same 
soundcard and a centrino setup. I am running Susu 9.1 pro (a 2.6 
kernel). For the first couple of days I had no problems. Then I started 
to play with acpi settings and enabled suspend-to-ram and 
suspend-to-disk. Suspend-to-disk worked but suspend-to-ram gave the 
wellknown "black screen after attempt to reactive". After that one bad 
experience I started getting exactly the same messages as you have (and 
I was unable to get any sound from eg. xmms). This persisted through 
reboots. 

However, in windows I could use the soundcard!

Today I tried rebooting "failsafe", which passes -noacpi to the 
kernel. I still had problems with the soundcard - stopping and starting 
alsasound gave a "failed to restore previous settings". I ran alsactrl 
and reconfigured my soundcard, which still gave some error messages. 
However, upon a straight reboot, everything is back to normal in KDE! I 
don't know whether the problem will return (hope not) - but I suspect 
that it started because of the "suspend to ram" stuff which I think kind 
of puts everything into sleep mode. I gues a -noacpi reboot together 
with alsactrl may have woken the soundcard up.

However, maybe I just experienced a single lucky reboot...
