Hello all! I've been using Arch for a while now and like to think that I have some grasp on the things that I need to understand, but this problem has me feeling like a total idiot because I cannot for the life of me figure it out.
Right now, my problem is that I am only getting audio output through the front-left audio channel, which sounds mono in my headphones. I have no idea what the problem is, as it was working perfectly just a few hours ago. If it helps, it started when I installed the plasma-meta package and rebooted into the Plasma desktop (however, that may be completely unrelated).
I am running Pulseaudio, and everything seems to be set up properly in alsa mixer.
Here is some (potentially) useful output:
