After starting an Android emulator on a Mac the sound quality of a connected bluetooth headset can degrade. This happens because the emulator requests an access to a microphone which is the one built in to the connected bluetooth headset. MacOS provides the emulator with an access to the microphone and switches current bluetooth profile to a lower quality one used for speech. This degrades sound quality.
If microphone is not a required feature for your task, the microphone can be disabled in the emulator as follows:
Device Manager, then click on the “three vertical dots” icon of the emulator.
Show On Diskoption.
Finderfind and open for editing the
hw.audioInputproperty and set it to
hw.audioInput = no.
Now you should be able to enjoy the music in high quality and developer your awesome app at the same time.
