Comments/Problems:
No analogue sound on Tablet from Broadwell-U from intel smart sound chipset -
hw works on Buster but breaks on Bullseye
Card0 on Buster no longer detected on Bullseye
Tried installing Intel SOF drivers/firmware to no effect, forcing snd_hda_intel
via modprobe conf doesn't work either
Broadwell-U works eith with HDA or SOF drivers theoretically.
There is record of a kernel compilation flag to enable SOF functionality
SND_SOC_SOF_BROADWELL_SUPPORT=Y breaking legacy and snd_hda_intel too.
