The only thing muted is Line in, Mic, Mic Boos, Beep,
Aux, Capture, Capture.
Ive unmuted them all and still, no sound - from the bass.
There is no channel though.
From the left to right:
Maser, PCM, Front, Surround, Center, LFE, Side,
Line, Mic, Mic Boos, Beep , Aux, Capture, Capture.
There are three tabs at the top: Realtek ALC888,
USB Mixer, ATI R6xx HDMI.
On the sub itself, there is no on button, no volume
button. On the left side is the power cord and three
plugins. Left, Right & Input. The left plug looks like a small
RCA plug, the Right looks like a svideo plug and Input
has the green audio cable plugged into it.
I still cant start pavucontrol without it crashing and
removing all sound.
