I am running Ubuntu 14.04. I am trying to play the output
(amplified to line level) of a turntable through my computer with a
volume control that works. The audio output of the computer is via
an Nvidia hdmi to a surround sound preamp. The input is the analog
line in connection of a Xonar D2 sound card (eventually the D2 will
replace the surround sound preamp). I can play the records with
either of the below commands - built-in: or, try ecasound: Any suggestions would be greatly appreciated. The amixer output for each sound card is show below.
