Bug Description
I have an external HDMI monitor attached to my laptop and the nouveau drivers would detect it but I would only get a black screen and no display beside the cursor.
Using the NVIDIA drivers makes the external monitor work but it then disables the built-in audio and tries to send all audio via HDMI. Even the headphones will stop working.
If I rollback with the zsys backup everything works again. Manually reverting to nouveau doesn't bring the audio back.

The issue I am having seems similar to this: https:/ /bugs.launchpad .net/ubuntu/ +source/ alsa-driver/ +bug/1833161
It is definitely an issue after the NVIDIA driver installation. Headphones and built-in speakers stop working. Only the HDMI audio works. There was a small kernel update from 5.4.0-26-generic to 5.4.0-28-generic last night so I will try to see if that makes any difference.
