The analog output from my diskless media director is connected to the stereo input of the tv.
The TV volume is set to maximum in order to barely hear the video sound.
During AV Setup, I turned the volume setting to 100. (I'm not sure where to verify this setting on the media director.)
As alsamixer works great for the core, it doesn't appear to work for the diskless media director.
"alsamixer: function snd_ctl_open failed for default: No such device"
