Created attachment 151246 [details] the choice of the headsets SUMMARY adapter Wi-Fi 6E Bluetooth 5.2 EDUP-LOVE EP-9651GS (chipset Intel AX210) STEPS TO REPRODUCE 1. connect 2 headsets to the Bluetooth adapter (multiple audio receivers, feature of BT 5.2) 2. go to the plasma volume controller 3. OBSERVED RESULT You must choose between the headsets, one of them ! (see the capture) You cannot select the two headsets. EXPECTED RESULT You can select the two headsets SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: 5.24.4 KDE Frameworks Version: 5.96.0 Qt Version: 5.15.5 KDE Gears 22.04.3 ADDITIONAL INFORMATION

It's not a problem to send a stream to a multiple sound output using a feature of PW. It's a problem that PW( plasma-pa?) must use the new feature "multiple sound ouput" of bluetooth 5.2. pw (plasma-pa?) when Bluetooth is activated with several connected sound ouputs, must automatically, drive the sound to the Bluetooth "multiple output devices" service. Then Bluetooth manages to send itself the sound to the several output devices. No ? If not, why BT adds this feature ?
plasma-pa doesn't do anything with bluetooth directly, it only operates on what is exposed by PulseAudio/PipeWire. As said in https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/2636#note_1507580 the Linux stack currently doesn't support the bluetooth feature you mentioned, so there isn't really anything to do here on the Plasma side except for https://bugs.kde.org/show_bug.cgi?id=440536 *** This bug has been marked as a duplicate of bug 440536 ***
