Apart of a bit strange "Latency: 2 min, 5 max, 248 set" things seem
to look sane (BTW - the lowest non-zero value for latency which one
can try to set with 'setpci', and which will hold, is 8).
There is nothing in drivers included with a kernel which seem to
support this card; therefore I tried ALSA drivers. Here is what
I see with 'cat' on different entries in /proc/asound:

**** version
Advanced Linux Sound Architecture Driver Version 0.4.1c.
Compiled on Oct 25 1999 for kernel 2.2.13-smp (SMP).
So everything seems to be peachy, right? The only trouble
is that I am not getting any sound coming from my speakers.
Nothing bad happens but no sound either. Do I miss something
on a kernel side here? Any sound advice? :-)
Thanks,
Michal
