Created attachment 165750 [details] 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 SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.93.0 KDE Frameworks Version: 5.249.0 Qt Version: 6.7.0 Kernel Version: 6.7.4-arch1-1 (64-bit) Graphics Platform: Wayland Processors: 8 × 11th Gen Intel® Core™ i5-1135G7 @ 2.40GHz Memory: 15.3 GiB of RAM Graphics Processor: Mesa Intel® Xe Graphics Manufacturer: LENOVO Product Name: 20XYCTO1WW System Version: ThinkPad X1 Yoga Gen 6 ADDITIONAL INFORMATION Docking station used is a Dell WD19TBS
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.
