Description

While in a call, FaceTime ordinarily lowers all other apps'/devices' volume. As such, it also lowers the volume for the BackgroundMusic device.

Selecting BackgroundMusic as output device in FaceTime itself has no influence on this and just makes it so FaceTime ducks itself as well (ordinarily choosing a virtual/different output device restores regular volume levels for other apps/devices).

It doesn't seem like BM can control FaceTime's volume at all in my tests.

Version: BackgroundMusic 0.2.0-SNAPSHOT-e83d07f System: macOS High Sierra 10.13.3

Contributor guide

Research direction
Investigate how FaceTime interacts with system audio levels. Check if BackgroundMusic can intercept the audio ducking by modifying volume settings. Look into Apple's Core Audio APIs for volume control and ducking behavior.
