Hello!
My audio dies, espcially when my system is under heavy load.
Otherwise I can maybe play music for an half hour, (with choppy sound).
I need to reload the module (snd_ich), every time it dies. Tryed to
compile it into the kernel but with the same result. The difference is
that I can't "restart" the sound, and need to reboot.
Sometimes it works better to not use the virtual channels, but the
driver dies anyway in the end...
mplayer says:
Audio write: Invalid argument
and dmesg reports:
pcm0:virtual:0:dsp0.2: play interrupt timeout, channel dead
pcm0:virtual:0:dsp0.2: play interrupt timeout, channel dead
Added hint.pcm.0.buffersize="16384" to /boot/device.hints, with not much
difference.
The same problem occures in FreeBSD 6.1 RELEASE, aswell.
Didn't have any problem at all with audio in NetBSD 3.0, don't know
which driver I used, because I never needed to touch it.
The specs on Toshiba.com says:

Compatibility: Windows Sound System V2.0
and Sound Blaster Pro compatible

Sorry for this awful long email, but I have been looking for a solution for
LONG time. :(
