Doing a echo123 shows:

 Call failed problem with audio playback

I have:

crw-rw-rw-  1 root  wheel  42, 0 Jun 20 09:54 /emul/linux/dev/sound0
lrwx------  1 root  wheel      6 Jun 20 09:54 /emul/linux/dev/sound -> sound0
lrwxr-xr-x  1 root  wheel      5 Jun 20 09:54 /emul/linux/dev/dsp -> sound

ktrace showed some ioctl errors like:

I have no idea if related, but I also did:

$ audioctl -w full_duplex=1 
full_duplex: -> 1
$ audioctl -w fullduplex=1  
fullduplex: -> 1

audioctl says I have:

name=ICH6 AC97
version=0x03
config=auich0

dmesg includes:

The two Cc's are because I saw you emailed about problems with Skype 
too. Anything fixed for you?

Anyone using skype?
