>Description:
There's no audio signal coming out from the audio chip. Everything else seems 
to work perfectly, no complains from applications using the audio device etc. 
This affects both /dev/audio and /dev/sound

NetBSD <= 4.0 worked fine. The first version of -current I tried was from 
20071222.

Playing around with audioctl had no effect (there's only one output port 
anyway).
