Why are you mentioning the GPU? What is the output of amixer -c0 scontents?

comment Alsamixer cannot be found
cannot open mixer: implies that the file that is not found is the device file. Apparently, your sound driver is not loaded. Show the contents of /proc/asound/cards, and the lspci output of your sound devices.

Get the control settings with amixer contents when it works and when it doesn't. What is the difference?

Reinstalling should not be necessary. Can you leave out any of those steps?

comment Asus Xonar DGX recognized but no sound
It just means that lspci could not read some information because it was not run as root. Anyway, did you tell Ubuntu that you want to use the DGX, and not the GPU's HDMI output?

If you do not hear any difference, why do you think there is one?

Unload and reload the snd-usb-audio module. Are there any messages in the system log?

comment Xubuntu 14.04 USB sound card problems
alsamixer changes a device's mixer controls; it does not affect what device other programs choose to use. Can't you switch devices in the sound configuration? Did you try pavucontrol?

This is probably a "feature" of the device's firmware.

comment Ubuntu 14.04.1 Fresh Install - No Sound
asound.conf affects only programs using ALSA. Tell PulseAudio that you want to use the PCH device (pavucontrol).

comment Play sound at a given volume bypassing system volume
The master volume always affects all sounds played; that's why it's called "Master".
