Description Brodey Dover 2010-09-04 18:20:04 UTC
Even with controls maxed out, there is no audio gain and the line-level volume is passed through.

drivers seem to load:
[brodey@pcbsd-4922 /usr/home/brodey]$ cat /dev/sndstat 
FreeBSD Audio Driver (newpcm: 64bit 2009061500/amd64)
Installed devices:
pcm0: <HDA Analog Devices AD1988B PCM #0 Analog> (play/rec) default
pcm1: <HDA Analog Devices AD1988B PCM #1 Analog> (play)
pcm2: <HDA Analog Devices AD1988B PCM #2 Digital> (play)

Mixer seems fine:
[brodey@pcbsd-4922 /usr/home/brodey]$ mixer

Responsible Changed
From-To: freebsd-amd64->freebsd-multimedia

Over to maintainer(s). 

To dubmitter: do you mean that the line-in is passed to the line-out 
without amplification?  Have you tried adjusting the igain? 

Could you also please provide the output of: 
sysctl dev.hdac.0.pindump=1 ; grep hda /var/log/messages
