Thanks for the message. Telling me how things are supposed to work in theory doesn’t really help me much. I need an actual solution to this issue. I’ve installed FW13 driver bundles, reinstalled the BIOS, resetted the mainboard. Nothing has provided a solution to this.
It does appear to be a software issue.
I have checked audio devices and the headphones audio device does not disappear. When plugged in, it simply shows as “ready”.
No sound output device switching happens without a manual input from me.
