audio0 causes kernel panic in -current

Hello all!

I finally succeeded in building a new -current system
as using the sources of around the middle of the last week.
The build proceeded without problems, the scripts just failed
to locate the toolchain sometimes, but with explicit setting
it via -T everything build nicely.

But when starting the INSTALL or RPC_WSCONS kernel, it hangs
with an:
audio0 at vidcaudio0: half duplex
panic: audioattach: audio_set_defaults failed


Any suggestions?
