Yes, I have them. But I can't hear what I'm recording, either through
headphones or through speakers, no matters if HP independent is enabled
or disabled. Attached is the alsa-info.sh output after the last test:
recording through the rear-mic and trying to hear through the HP with
HP independent disbled, all related switches on and high volume level.
