When switching from Windows to Ubuntu 18.04, my sound card (Asus Xonar DGX) didn’t seem to work anymore.
After searching around a little bit I found a really easy fix:
- In Settings/Sound, select Xonar DGX as the default output using the “Analog Surround 5.1 Output” profile
alsamixerin a terminal, select the right sound card (F6), go to “Analog Output” (arrow right) and select “Multichannel” (arrow up)
Now surround is working using the Xonar DGX sound card. However, even 2 channel audio was being played over all 5 speakers now. To prevent “upmixing” from 2 channel audio to 5 channel audio, you can disable it:
- Find (or add) the
enable-remixingsetting and set it to
- Restart your PC
