I see you saw the /r/linux thread: https://www.reddit.com/r/linux/comments/68jy8l/kde_users_how_do_you_switch_between_two_audio/ Going to suggest another test: 1. Open mpv with audio playing. 2. Set DeviceA as default 3. Close mpv 4. Set DeviceB as default 5. Open mpv, which device does it start on? The user will expect DeviceB not DeviceA.
