Erik,
Congratulation for finding the problem. I actually had several questions sent
to Jon about the new release of nas (version 1.5). Hopefully, we can get
libaudiooss working on next nas release.
Here attaches the output you want and I just restarted the nasd server on
port 8041.
Good luck,
Ziying
