alsa-project/alsa-lib issue #201 was opened from riveravaldez:

Hi, I'm having some hangs with an until-yesterday perfectly-working setup. Only way to fix it seems to be restarting JACK.

Looking at system messages I found:

This is a ThinkPad X220T with updated Debian 11 (Stable) with the internal audio-interface turned-off through PA and an external Behringer U-PHORIA UMC22 handling all the audio.

Sorry if this is useless or out of place. I'm reporting just in case (considering the PA message about a possible ALSA driver bug).

Thanks a lot in advance. Any recommendation would be most welcome.

Kind regards.
