I have a G15 Gaming Keyboard and an Auzentech X-Meridian sound card.
When I open Alsa Mixer, I have 5 'Master' controls. 3 are Stereo Controls, 2 are Mono controls. These Master controls handle each of the amps for the 7.1 sound card.
The issue I'm having is when I use the volume control on the keyboard, the 1st Master is controlled, and the other 4 masters get set to zero, thereby disabling my surround sound settings.
In investigating the keybind settings, I've set the Keyboard Setting (for XFCE) for G15 Keyboard. The volume control is bound to XF86Audio[Raise/Lower]Volume.
My question is what to set so that all 5 'master' controls are affected when I use the volume control.
