I started a sounddriver for Linux who could do that (and still does on my
It´s working for SB16 cards, Terra Tech Base1, and ..uhm ..Turtle Beach
Ah, yes the es1668 chip based cards. Otherwise it supports the OSS API, so all
standard Apps work.

I think I am the only user of this driver ... it wasn´t really a great success.

Yes, and there´s another sound server (can´t remember it´s name).
I have written a sound server which mimics the SGI audio library, it was called
(Actually a shame that I didn´t make that public).

All this server based solutions will introduce an additional delay and .... will
your /dev/dsp too. ....

That would be really cool.  We could implement an ALSA API that just connects to
pd instead
of the sound devices. We then would only have to recompile ALSA aware
(e.g CSound ..)

Why not, if there´s enough interest .... (and Beer :R )
