Bug Description
[Impact]
This Dell machine has dual Realtek 4050 USB Codecs as front and rear codec, the front codec has speaker and headset, the rear codec has line-out audio jack. Without UCM, the pulseaudio can't detect this two usb audio codec and the audio can't work at all.
[Fix]
Backport a upstream patch, the patch adds the front and rear profiles in the ucm, then pulseaudio will enable all audio devices in this machine.
[Test]
booting with patched ucm, open the gnome-sound-
[Where problems could occur]
This SRU adds the new ucm files to a folder, in theory it will not introduce regressions, but It adds a file USB-Audio.conf, it could make other ucm conf files in the USB-Audio folder fail to parse, and make the P620 and WD15/19's audio fail to work, but this possibility is very low, we already tested it and no regression found so far.

This is the debdiff for Jammy and Impish. (Jammy and Impish share the same alsa-ucm-conf so far, I prepared a alsa-ucm-conf for jammy based on the latest debian version, it is in https:/ /launchpad. net/~hui. wang/+archive/ ubuntu/ new-jammy, if it could be merged, I will prepare a new SRU for jammy then).
