alsa-ucm groups by driver name so fill that in as well. Otherwise the

Before:

Unfortunately this change broke multichannel audio on my Rock64 device running
Debian. My Rock64 is connected to my AVR (Pioneer SC-1224) via a HDMI cable.
This looks like an user space configuration problem. You should check, if a PA
profile or an UCM configuration is used (in the PA debug log).
