My computer turned off for no reason yesterday and now the sound does not work at all. The default sound card on alsamixer has become “Loopback” and the only other option is Intel. Switching to Intel card doesn’t restore the sound either, I believe this is for the HDMI port. I am pretty sure I have a realtek card on my laptop but it does not show up in alsamixer.
This is my output after running alsa-info.sh
