On my Pinebook Pro I get no sound through my wired headphones. These are headphones that I had always used for listening to audio, and now they no longer emit any sound. However, the headphones are fine, as when I connect them to my smartphone I do get audio through them.
I’m using KDE Plasma 5.25.4 and I think the problem started with one of the latest stable updates, although I can’t tell which one as I’ve been a few months without using the headset.
The strangest thing is that the system detects the headphones, which do not play any sound, but does not detect the speakers, which work without any problem. Here I attach an image.
Well, I have decided to reinstall from scratch Manjaro Plasma on my Pinebook Pro, as I couldn’t find any solution to the problem. And with this I managed to solve it. It seems that now the audio works perfectly, both with the speakers and with the headphones, either wired or via bluetooth.
Surely, when I upgraded from a previous version something went wrong. Sometimes it happens with rolling release distros.
