SUMMARY
I have a laptop connected to 2 external monitors via daisy chaining.
The two monitors are connected via DisplayPort cable, the laptop connects to
one monitor via DP over USB-C.
The setup works, but I have a mildly frustrating problem.
The main monitor has connected a speaker via the headphone Jack; the device
presented in the System Settings shows thus 3 profiles:
* Digital Stereo (HDMI) Output
* Digital Stereo (HDMI 2) Output
* Pro Audio
The first 2 profiles are for the headset jacks for monitor 1 and 2.
However, the profiles get swapped for no apparent reason.
Thus, I find myself without audio.
The workaround right now is to
1. Switch profile
2. Plasma swaps device in step 1, so re-select the monitor as output device
3. Sound works again
The issue is very consistent but I can't trace what causes it, if Plasma or
PipeWire/WirePlumber.
STEPS TO REPRODUCE
1. Have a setup similar to the above with 2 monitors with headphone jacks and a
device in one of them
2. Use the connected device
3. Reboot the device
OBSERVED RESULT
Profiles e.g. outputs are swapped between the 2 monitors
EXPECTED RESULT
The profiles "stick" to the respective monitor
