I understand this is a common request.
I followed the Chrultrabook instructions to replace the firmware on my Acer Chromebook Spin 511 and install Linux Mint 22.2. I also followed WeirdTreeThing’s instructions to install his audio fix, and it’s still not working.
The Audio settings show the output device as “Dummy Output” and no sound comes out. Weirdly, if I plug in headphones into the headphones jack, it suddenly displays my driver correctly and plays sound out of my speakers! This is the only way I can get it to make any sound out of the speakers, and there’s no way to make headphone audio work.
Any help would be greatly appreciated. Here is the debug file, as requested:
