SUMMARY Since iTunes refuses to run under Wine, I've been using my laptop as an output device for my phone's Bluetooth audio, and playing music on my laptop like that. The only issue with this is that although my phone's now playing is displayed in the Bluetooth system tray widget, it isn't reported under the global now playing widget. STEPS TO REPRODUCE 1. Use a tool such as Blueman to set your device running KDE up as an audio receiver 2. Connect to your KDE device over Bluetooth using another device such as a phone running Android or iOS. 3. Play media on your portable device, with the selected output being your KDE device. OBSERVED RESULT The now playing information is provided in the Bluetooth options panel, but not in the global now playing panel EXPECTED RESULT The now playing information is listed in the global now playing panel as well as in the Bluetooth options panel. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Manjaro KDE (available in About System) KDE Plasma Version: 5.22.5 KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
As a workaround, you can run BlueZ's mpris-proxy utility, and (as of KDE 5.27.3) Bluetooth media info will show up in the Media Player widget. Keyboard media hotkeys will also work. I have it set up as a systemd service, so I don't have to run it manually.
