Android emulator degrades bluetooth sound quality

When running an Android emulator on a Mac, the sound quality of a connected Bluetooth headset may degrade. This occurs because the emulator accesses the headset’s built-in microphone, prompting macOS to switch to a lower-quality Bluetooth profile for speech.

If you don’t need the microphone in your app, you can disable it in the emulator:

1. Open Device Manager, then click on the “three vertical dots” icon of the emulator.
2. Choose Show On Disk option.
3. In the opened Finder find and open for editing the config.ini file.
4. Find hw.audioInput property and set it to hw.audioInput = no.
5. Save changes and restart the emulator.

Now you can enjoy high-quality audio while developing your app!
