After W11 22H2 update I also had sound problems with USB external Audio Interface (UMC22) .
There was no problem with bluetooth and headphone jack inputs. After checking the speakers, audio interface and computer cables and restarting the devices, the problem persisted.
I had sound problem only with UMC22 USB Audio CODEC.
I also reinstalled ASIO4ALL 2.15, 2.14 and 2.13 versions but that didn't work either.
When I uninstalled the USB Audio CODEC driver from the device manager and restarted the computer, I could only get an extremely low volume with the headphones.
Finally, I uninstalled Intel Smart Sound Technology for USB Audio and USB Audio CODEC drivers from device manager and all ASIO4ALL installation and restarted my computer.
After the computer was turned on, I just installed the latest version of ASIO4ALL 1.5 and it started working as before.
