>Description:
With a kernel as of last night suddenly this audio device:

audiocs0 at sbus0 slot 13 offset 0xc000000 vector 24 ipl 8: CS4231A
audio0 at audiocs0: full duplex
audiocs0: WARNING: power management not supported
auxio0 at sbus0 slot 15 offset 0x1900000

the default mixerctl values have monitor.master set to 80,0 - which is
barely noticable in my slightly noisy office ;-)

Previously the default was 220,220.

Also note this strange audioctl output:

properties=full_duplex
full_duplex=0
fullduplex=0

(but this has not change recently - just noticed while looking for the
missing sound)

>How-To-Repeat:
Boot an U2 with -current.
