I had sound working fine with one problem: the center and rear right channel were swapped.

I generated an /etc/asound.conf to work on the channel swap and reloaded and now I can see the audio in pulse audio monitor, but nothing from the speakers. I deleted asound.conf and rebooted and it’s now back to the previous settings but still having an issue with no sound from the speakers.

Any help is appreciated. I’m still also trying to figure out how to rearrange the surround channels so they are assigned to the correct speakers. Changing them from the hardware isn’t an option unfortunately.
