In Windows 10 you can have multiple audio devices at once. One can be used as the default audio device and another can be used as the default communication device.

The HipChat calls appear to select the default audio device for all calls and don't give me a way to change this. This means the wrong audio outputs are always selected.

This is particularly bad when you are using a Bluetooth headset that supports two audio profiles (one for music and one for calls).

When I make an audio call with this setup it doesn't switch to the correct audio profile so I can't hear the other person but they can hear me (because I only have one Mic setup). It makes me think calling is totally broken, But the reality is it isn't switching to the right audio output device.
