Comment 37 for bug 1851518

I just installed a fresh Xubuntu 20.04 (Linux 5.4.0-42-generic) on my brand new Samsung Galaxy Book Ion NT950XCJ-X716A. And of course I do experience the issues described here: very low volume on headphones and no sound on speakers.

In pavucontrol, under "Output devices", I see 3 HDMI outputs, and the last one is "Speaker + Headphones". I would have expected to see something like "Built-in Audio Analog Stereo", but it's not there. Under "Configuration", I would also expect something related to built-in, but the only profiles available are "Play HiFi quality Music" and "Off".

From reading this thread it seems that a (partial?) fix is on the way. Is there a way for me try that patch already ?

And is there anything else I can do to help fix the remaining issues ? I am not sure what log are useful and how to get them ?
