Input audio by Bluetooth headset

Recently I want to use TX2 for voice recognition. After connecting a Bluetooth headset, Tx2 can output audio (listen to songs, etc.), but there is no response when recording through the recording software named Audacity. How can I input voice through Bluetooth headset?

Hi crow_108,

Please run below steps to enable BT audio:

1. sudo vim /lib/systemd/system/bluetooth.service.d/nv-bluetooth-service.conf
2. Remove all options for no plugin, it should look like below:
   ExecStart=/usr/lib/bluetooth/bluetoothd. -d
3. sudo apt-get update
4. sudo apt-get install pulseaudio-module-bluetooth
5. sudo reboot
6. Pair and bluetooth audio devices.
