Hey!

When using PulseAudio from experimental with the version of
alsa-ucm-conf from unstable, the sound is not working properly on
sound cards relying on UCM, like the Thinkpad Carbon X1 7th gen
because the number of channels should default to stereo.

The patch upstream is available here:

https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/commit/cabd387e26b5fe03661f4b894826c7c6b58d7efa

I am using it since a couple months without any issue. It will be part
of PulseAudio 14. Since it's unknown when a release of 13.99.2 or 14
will happen, could you include this patch in Debian packaging so that
people with a SOF sound card (many recent laptops I believe) could
have something working without recompiling PulseAudio?

Thanks.
