ALSA Sound - VIA 82xx
Having trouble getting the volume control to work correctly in Myth;
I can hear the audio, but it's always at full volume.
I can see the OSD with the volume meter going up and down but I
always get full volume at any level (other than zero, which does mute
I've got Myth selected to handle the Internal Volume control in General
I'm currently using "ALSA:default" for the "audio output device", but
For the "mixer device", I'm using "/dev/mixer". This is the only path
cause an error when trying to watch TV. I have also tried "default",
"ALSA:hw:0,0", "ALSA:hw:16,0", "/dev/mixer0", and a number of other
but they all cause errors.
What should I set this to?
When I look at alsamixer, the Master and PCM volumes will not budge and the
"VIA DXS" slider is the only control that actually adjusts the sound volume.
