Audio in Docker Container

Reference

https://stackoverflow.com/questions/28985714/run-apps-using-audio-in-a-docker-container

To play audio in docker container, you will need to map the audio device of the host to the container

docker run -ti --rm \
    -v /dev/snd:/dev/snd \
     --privileged \
    myContainer sh -c "echo run something"`

For MacOS, PulseAudio needs to be installed

Install Pulse Audio

brew install pulseaudio

Run the daemon (starting using brew services has some issues so use the start command manually)

pulseaudio --load=module-native-protocol-tcp --exit-idle-time=-1 --daemon

To run as service, additional steps are required

Edit the config file located in /usr/local/Cellar/pulseaudio/14.2/homebrew.mxcl.pulseaudio.plist

Add in the additional argument for --load=module-native-protocol-tcp
