I just installed manjaro linux KDE, and there are absolutely no sounds. I tried un-muting several times and following several tutorials, including this one: doc. ubuntu-fr. org/ audio_intel_hda (had to put spaces otherwise I couldn’t sent the message) but it doesn’t include my laptop. My laptop is a testing laptop from the french brand Unowhy, and it is not even in the market so I’m not surprised it isn’t in that list.
If that helps, the output of
lspci | grep -i audio:
00:1f.3 Audio device: Intel Corporation Comet Lake PCH-LP cAVS
However, when I plug in my USB headset, everything works perfectly. I had the same issue on all linux distros I tested (pop os, ubuntu KDE, manjaro gnome and the one I’m currently using, manjaro KDE)
Thanks in advance !
