I don't think so. I think you either forgot to specify the correct
module parameters, or you somehow loaded the kernel Soundblaster
driver.
Did you read the file Documentation/Changes in the kernel source tree?
The linux-2.4 kernels need quite some new userland programs to work
properly.

ou just do a multiply ? :))
It's not only a system call issue, it's just that software mixing
should not be done in kernel. See also:

You should consider disabling devfs completely, because it is known
broken (read a linux-kernel archive for more information). Mandrake
issued
ng in massive filesystem corruption. See a linux-kernel mailing
list archive for more information (see http://www.tux.org/lkml/ ).

This is an excellent example of a function that shouldn't be changed.
If it is called with a NULL pcm parameter, it's a programming error of
the calling function.

More important is that C code can be easily ported to any architecture
you want.

Yes, please do. I'm pretty much interested if this class D amplifier
will work. I've been thinking about doing such an amplifier myself, but
never got so much as building one.

Yes, the PC has some timers, but I'm not sure they go as fast as 44kHz.

Interrupt call while in APM powersave mode, that could be a broken APM
BIOS. Did you by any change enable "Allow interrupts during APM BIOS
calls" in your kernel? If so, could disable it and try to recreate the
problem?

Oh, and speaking about high quality, Burr-Brown also has a USB audio
codec chip. I don't know the exact part number, but details and data
sheets are available on their website (www.burr-brown.com).
