Audio via DisplayPort stopped working after upgrade

[Maksim Beliaev]

After the recent upgrade audio via my external screen stopped working.

My setup is following:
1. Laptop
2. Dock station connected via Thunderbolt 4
3. 2 Displays connected via DisplayPorts

In the past audio worked just fine via external monitor. Now it stopped working and works only via laptop integrated speakers or headset
