Hello,
since I had some issues with azalia sound on OpenBSD 4.0, I decided to

follow -current.  The good news: the system doesn't crash anymore when

typing in 'audioctl -a'.  The bad news: sound still doesn't work.
When I type in:

# cat /bsd > /dev/audio

I get

ksh: cannot create /dev/audio: Invalid argument

and /var/log/messages shows

Mar  9 23:47:34 puffy /bsd: didn't find Record rate 44100
I'm not sure if this is a problem with my audio settings or with the

device driver.  Changing play.rate to any other value yields the same

error message in /var/log/messages.
Here's the output of audioctl -a:
