You're correct - sorry about that. I normally use OSS compat (/dev/dsp)
and everything works fine. When I do the test mentioned above, I see
video fine, but no sound.
There is *physically* another sound card in the system, but I'm 99.9%
sure that's not the problem b/c I believe it's disabled in BIOS and ALSA
certainly doesn't know about it:
[root at xyz root]# cat /proc/asound/cards
0 [M2496 ]: ICE1712 - M Audio Delta DiO 2496
M Audio Delta DiO 2496 at 0xdc00, irq 9
Let me know what else I can do to help troubleshoot.
Thanks,
Brian
