Hi,

Virtual OSS from my I4B SVN can do this.

svn --username anonsvn --password anonsvn \
       checkout svn://svn.turbocat.net/i4b

cd i4b/trunk/virtual_oss

make all install

kldload cuse
kldload cuse4bsd

sysctl hw.snd.basename_clone=0
virtual_oss -C2 -c 2 -b 16 -S -r 48000 -s 1000 -P /dev/dspX -R /dev/dspY 
-d dsp

--HPS
