Debian 11 audio was working great on my 4K HDMI monitor(tv) until the update came along. The HDMI audio still works with an older computer (and it is the latest Debian 11 also).
The problem child is a Dell Precision 5560 (vPro i9) using the Dell power adapter with the HDMI/USB ports.
The audio when HDMI 5 or 7 when enabled shows output under the "output Devices" as audio is playing, but nothing outputs on the monitor.
NVidia driver are installed, but Nouveau did not work either.
The non-free drivers are all installed...
So I am thinking this is a Dell specific problem (internal switch or something), if anyone else has a Dell laptop of similar class that has seen this problem. Built-in audio on the laptop stinks.

Thanks, but no change.It might have been 5.10.0-18 that worked, so maybe I will try that.
This laptop also has strange Bluetooth issues with the built in adapter, but fortunately that and HDMI audio do not interfere with getting work done.
