oui but I got some interesting results - I now only have output from one DAC (DAC00) and only one master.outputs, sound from speakers get automatically muted when headphones are plugged
Yes, and when I changed my config keys to match yours a few weeks ago, I managed to duplicate your sound setup😁: 2 DACs; independent speaker and HP; and the inability to shift balance using audioctl
--but no sound-bleeding artifacts.
Thanks for the diagrams, I'll look 'em over in detail during the weekend, but, it looks like you will need kernel fixups. Linux has these "fixups" for the widgets in case the BIOS mis-configures things; NetBSD simply uses what the BIOS set-up.
I'll send you a test patch on the weekend. In the meantime, try updating to the latest BIOS.
