I've tried almost every post here. Restarting alsa, reinstall all the packages.
This issue is seemingly random. Headphones plugged in, plugged them out for maybe 5 minutes, plugged back in, and now there is no way to get back right-side of audio. I've restarted laptop (Dell XPS) multiple times when restarting audio, deleting or trying configs...
I've tested multiple headphones (they all work outside this laptop), to no avail.
Anyone have any ideas how I can get the audio drivers to pick up the right side again like it did a few minutes ago? It's for realtek, XPS 13.
