Alright. Here's where I'm at.
Audio jack works, but is not recognizing headsets with mics on the same device (only one headphone jack, I'm sure you know this lol).
Sleep seems to work fine, no issues with sound/wifi/anything afterwards.
bluetooth works. Tested with an audio device, registered both mic and audio output on the headset.
HDMI works, including HDMI Audio, however when I was testing that, I found a weird issue. I realized that my laptop is currently only running at 1366x768. When plugged into the TV, it switched scaling for both the TV and the built-in monitor to 1080p. I know from when windows was installed that the laptop is natively 1080p, but when not plugged into the TV, it refuses to give 1080p as an option to set the display to.
Can't test DisplayPort, as I have no way of doing so currently, Will test that another day, however I don't think I'll ever use it.
TL;DR
Scaling on the internal display won't get to 1080p (the display is capable)
Audio jack is not recognizing mic-in on headsets.
Otherwise everything is fine.
