Also, I have now upgraded to BIOS 04.04. I haven’t had the audio issues yet today, so fingers crossed.
Also, I guess it is not supposed to be able to charge from the front ports (according to Port differences - #4 by Destroya ) – I honestly just had no idea about this, and it has been mostly doing display output even when I plugged HDMI into the front left port, but maybe it just isn’t reliable in that port… who knows. I moved the display expansion card and I’ll obey what’s in that listing of the different ports, and see if I have issues when running it that way.
