Recently I found strange thing: I have no sound on speakers. There is no problem with usb headphone, or headphone via jack but speakers are silent. As I almost exclusively use usb headphones I have no idea when this problem started. In theory is possible that speakers are broken but the same thing on completely different laptpop. I tried to play with: --8<---------------cut here---------------start------------->8--- options snd-intel-dspcfg dsp_driver= --8<---------------cut here---------------end--------------->8--- but without success. Any hints? During my searching I found https://bbsarchlinux.org/viewtopic.php?id=275061 https://bugzilla.kernel.org/show_bug.cgi?id=216139 but I am not sure if this is related.
