no sound at all in pcbsd9 gnome

[bsdaddict]

Hi,
I'm getting no sound at all in gnome (running pc-bsd 9 amd64). No system sounds, no sound from flash animations, no sound from a mp3 playing.

The mixer settings :
[beni@bsdaddict ~]$ mixer
Mixer vol is currently set to 85:85
Mixer pcm is currently set to 75:75
[beni@bsdaddict ~]$

Trying to adjust the mic gives me this error :
[beni@bsdaddict ~]$ mixer mic 75:75
mixer: unknown device: mic
usage: mixer [-f device] [-s | -S] [dev [+|-][voll[:[+|-]volr]] ...
mixer [-f device] [-s | -S] recsrc ...
mixer [-f device] [-s | -S] {^|+|-|=}rec rdev ...
devices: vol, pcm
[beni@bsdaddict ~]$

My sysctl settings :
[beni@bsdaddict ~]$ sysctl -a | grep hw.snd.default
hw.snd.default_unit: 1
hw.snd.default_auto: 1
[beni@bsdaddict ~]$

My dmesg gets filled with these messages :
