React Native, Android emulator prevent janky bluetooth output

Aug 2023

When the Android emulator starts it causes microphones to start recording, if you are using Bluetooth headphones, this causes a significant drop in quality.

You can disable audio input permanently on the emulator by editing:

~/.android/avd/<emulator-device-name>.avd/config.ini

Change the following lines:

hw.audioInput = no
hw.audioOutput = no
