SOLVED: journalctl -f shows constant headphone & microphone events

Edit: I pretty much ignored this issue, but today gave it another look. Ultimately, I solved it by opening my computer case and unplugging the front headphone/microphone cable from the motherboard. Before doing that, I had edited /etc/acpi/handler.sh and defined jack/headphone and jack/microphone to list the other command line variables the script received. By doing that, I found out the event that kept repeating for both was plug and unplug over and over. Luckily, it was the front jacks that I could unplug internally instead of the back ones that are part of the motherboard.

Following this part of the acpid ArchWiki, https://wiki.archlinux.org/index.php/Ac … figuration, I discovered something strange. Here is just 5 seconds of output after trying journalctl -f:

This isn't normal, is it? How should I go about diagnosing this?

When I posted the above output, I was listening to a live youtube stream, but the same thing is happening even when nothing is playing. this is on a desktop computer that does not have anything plugged into the headphone or microphone jacks. I am not using pulseaudio. My sound and video is always going through HDMI to my TV which I use as a monitor.
