I'm playing with a soundblaster card.
With /dev/volume I can control the cd volume.
(Russ: I like your mixer program! Thanks!
 Note: on my system it needed minor changes to compile)
But, when I redirect sound bytes to /dev/audio nothing seems
to happen; after uncommenting the commented-out print statements
in /sys/src/9/port/devaudio.c  I get '#A: audio timeout' messages.

The system is a 150 Mhz pentium-s (according to boot msgs).
The sound blaster card (ISA) says while booting something like:
   creative VibraX16 PNP
It has a note (c) 1997 on the card.
(is this enough to identify it?)
Is this one simply not compatible enough? Or??

On a related note:
I installed mpg123 (using Tad Hunt's patch). When I run it,
I get a 'division by zero' error in layer3.c:172
When it breaks, i==9.
Any ideas?
(I hacked around this by inserting an explicit test; since I don't
hear the audio anyway I cannot say how that influences sound quality)

(I also installed mpeg3play, which does seem to work,
as far as I can judge without being able to hear the audio)

Thanks, as always,
Axel.
