Audio/video issues and no sound in any browser since new install

Hello everybody, it's been a while since I posted anything. After a failed upgrade, I decided to start with a clean slate and reinstalled Arch from scratch again with a brand new freshly downloaded image. Now I have several excruciently annoying issues: First off, there is absolutely no sound what so ever coming out of any web browser (playing youtube vids). Second, I used to use mpv to play music in the background. Both, mpv and mplayer are not working, despite of being freshly installed from updated repositories. I removed mpv and alsa, then reinstalled alsa to see if mpv got in alsa's way somehow. Still no sound. I also noticed that the level bar for PCM is missing in alsamixer. I installed mplayer to see if at least that works. Nada. it complains about mismatching headers and so on. Before I removed mpv, it was complaining about not finding /dev/dsp, something about jack, etc. Why does mpv need jack anyways all of a sudden?? I noticed that sound works in the web browsers when started with sudo or as root, but my user account is in the Audio group, so it can't possibly be a permission issue, could it? Well here's the output of the issues that I get:

Audio errors produced in both Opera and Falkon

Re: Audio/video issues and no sound in any browser since new install

Your ALSA configuration is broken, if "starting as root" fixes this, you likely have a misguided ~/.asoundrc
