[PROBLEM] Randomly missing audio (HDMI) - VCHI service conn error

[georgew21]

IIRC multichannel USB audio requires Linux kernel 5.15.y branch. We may use this branch in upcoming moOde 8 release but no guarantee. Eventually though the 5.15.y branch will become the default in Raspberry Pi OS.

it will be great to have multichannel through usb, because for a 2.1 system (subwoofer + 2 spekaers) we need 3 channels to make room correction in right way with camilla.

thanks for nice work
