I don't have plans to support audio/oss, but I would be interested to 
diagnose this issue with snd_hda. Unfortunately, I am not sure what else 
can I do now without access to the hardware for low-level debugging. If 
somebody with the same netbook and the same problem appears at MeetBSD 
California or otherwise in San Jose in following days, I would be glad 
to look. Other problematic sound hardware is also welcome.
