Hi all,
as of today I have an Asus Xonar DGX installed in my PC. Front Speaker output works perfectly and out of the box, the same applies to the Front Mic. However, the Rear Speaker doesn't work out of the box at all.
To enable the Rear Speaker, I have to open alsamixer, select my Xonar DGX using F6, navigate to Analog Output and switch that value to Multichannel. Is it possible to automatically switch this depending on the Front Speaker being plugged in or not? This used to work perfectly with the onboard sound.
Next problem is that I have no way of controlling the volume of the Rear Speaker. In alsamixer, the only volume control is for the Headphone, which maps to the Front Speaker. In pulseaudio, there is a volume slider, but it has no effect on the actual volume.
So my question is: How can I have alsa/pulse/whatever auto-detect which output should be used, and allow me to adjust volume for both Front and Rear Speaker (preferably independently)?
Here is a bit of info about my system:
