Unable to connect KEF X300A USB speakers

alsa-project/alsa-lib issue #189 was opened from simbatl:

I'm trying to USE a pair of KEF X300A speakers. They work with aplay on Ubuntu 20.04 server, but fail on Ubuntu 18.04, 20.04 and 21.10 desktop.

Here is output from pulseaudio -vvv: [pulse.log](https://github.com/alsa-project/alsa-lib/files/7527770/pulse.log)

And here is output from alsa-info.sh: [alsa-info.txt](https://github.com/alsa-project/alsa-lib/files/7527773/alsa-info.txt)

Anyone who know how to solve this issue? :)
