In System Settings> Multimedia> Audio Volume, there is a tab titled "Configuration". In there, it lists my Bluetooth headset (Bose QuietComfort 35) with a "Profile" dropdown menu, which allows me to switch between A2DP and HSP/HFP. Whenever I change that setting to one of the two, however, all of the applications in the "Application" tab which _were_ assigned to the audio device "Bose QuietComfort 35" revert to "Built-in Audio Analog Stereo". Likewise, under the "Output Devices" tab, the default audio device reverts from the headset to "Built-in Audio Analog Stereo". Is it possible to keep the applications from switching to the internal "built-in" device when switching between Bluetooth headset profiles? It's just a hassle when I want to go on a call, or go off a call, to go into Multimedia settings and change _every single dropdown_ in the Applications tab to my Bluetooth headset, every single time. In addition to this, but probably would be a separate bug/feature request, is it possible to auto-switch to HSP/HFP mode when an application wants to use the microphone, and back to A2DP when it is no longer in use? Just like Android, iOS, and Windows do when a call comes up. Thanks in advance!
You should configure PulseAudio to do this for you, it's nothing that Audio Volume KCM takes care of.

> Did I get confused? Is this not the correct place to report bugs / feature requests for the Multimedia settings in System Settings? This is not what KCM Audio Volume is for. It only allows to change volume/options of the streams/devices, it is not an audio daemon. What you want is a responsibility of the daemon - PulseAudio.
