Audio Routing Setup

macOS Users

To route audio through Google Meet using BlackHole, follow these steps:

Step 1: Install BlackHole

1. Download BlackHole:

   • Go to the BlackHole GitHub page.
   • Click on the "Releases" section and download the latest version (usually a .dmg file).

2. Install BlackHole:

   • Open the downloaded .dmg file.
   • Follow the installation instructions:
     • Drag the BlackHole icon to your Applications folder.

Step 2: Create an Aggregate Device

1. Open Audio MIDI Setup:

   • Go to Applications > Utilities > Audio MIDI Setup.

2. Create an Aggregate Device:

   • Click the "+" button in the bottom left corner and select Create Aggregate Device.
   • In the right panel, check both your microphone (the physical one you use) and BlackHole 2ch.
   • This allows you to use your microphone while also routing audio through BlackHole.

Step 3: Set Up Audio Preferences

1. Set BlackHole as Default Input:

   • Go to System Preferences > Sound.
   • Under the Input tab, select BlackHole 2ch.

2. Set Your Output Device:

   • Under the Output tab, select your regular speakers or headphones.
   • If you want to hear the audio yourself while it plays in Google Meet, you can create a Multi-Output Device that includes both BlackHole and your speakers:
     • In Audio MIDI Setup, click the "+" button and select Create Multi-Output Device.
     • Check both BlackHole 2ch and your regular output device.

Step 4: Configure Google Meet

1. Open Google Meet:

   • Join a meeting.

2. Select BlackHole as Microphone:

   • Click on the three dots in the bottom right corner of the Meet window.
   • Go to Settings > Audio.
   • Set the microphone to BlackHole 2ch.

Step 5: Test the Setup

1. Play Audio:

   • Use your bot to play audio. Ensure that the audio is routed through BlackHole.
   • For example, in your bot code, you might have:

   os.system(f'afplay {audio_path}')  # This plays the audio through BlackHole

2. Check in Google Meet:

   • Ask someone in the meeting if they can hear the audio.
   • Adjust the volume as necessary.

Windows Users

To route audio through Google Meet using VB-Audio Virtual Cable, follow these steps:

1. Install VB-Audio Virtual Cable:

   • Download from the VB-Audio website.
   • Follow the installation instructions.

2. Set Up Virtual Cable:

   • Set the virtual cable as your default playback device in your sound settings.
   • Ensure that Google Meet is set to use the virtual cable as the microphone.

Linux Users

To route audio through Google Meet using PulseAudio, follow these steps:

1. Install PulseAudio:

   • Most Linux distributions come with PulseAudio pre-installed. If not, install it using your package manager.
   • For example, on Ubuntu, you can run:

     sudo apt-get install pulseaudio

2. Set Up Loopback:

   • Use the pactl command to create a loopback from your audio output to the microphone input:

     pactl load-module module-loopback

3. Configure Google Meet:

   • Ensure that Google Meet is set to use the PulseAudio input as the microphone.

Usage

1. Run the bot:

   python src/bot.py

2. Audio Playback:

   • Ensure that the audio file you want to play is in the correct format (e.g., .mp3 or .wav) and located in the specified directory.

Troubleshooting

• If you encounter issues with audio not being heard in Google Meet, ensure that:
  • The correct virtual audio device is set as the microphone input in Google Meet settings.
  • The audio file is playing correctly through the bot.
