OK. I have just now confirmed that our problem here is NOT in Win11. It occurs in Win10
too.
I have also removed all audio system drivers, have installed the most reliable version of the
Realtek audio drivers and have then connected the laptop to my own working (Win10)
system.
Result: the same problem as before: inputs and outputs are reversed.
Conclusion: a wiring or firmware error within the Acer laptop. Possible USB ports wired
wrong.
Fix (temporary): reverse the rx and tx wiring in the digital interface.
I will post photos and results as soon as I can.
