Audio panel

SUMMARY
With Plasma 5.x I could select HDMI directly from the Audio panel in the system tray and it would switch immediately. With exactly the same setup, and only updating to Plasma 6 RC 2 (same pipewire version, kernel, docking station, etc.), this doesn't work for me anymore. Audio is not send correctly to HDMI device as before.


STEPS TO REPRODUCE
1. Attack laptop to docking station (I'm using Thunderbolt 4)
2. HDMI audio shows correctly in the audio panel
3. Selecting HDMI removes audio from laptop's built-in speakers, but audio is not played in the monitor

OBSERVED RESULT
Not working as with Plasma 5.x

EXPECTED RESULT
Audio panel correctly switches audio to HDMI entry

Connecting the laptop directly via HDMI still works correctly. It is only when using a docking station that this case seems to be broken now.

Okay, closing since I cannot reproduce this issue anymore. I have rebooted the laptop several times, plug and unplug the docking station and it always works now. No idea what happen the first time. If I can reproduce I will reopen.
