Docker ALSA Player

This image implements a Dockerised ALSA player. It requires that you pass along the /dev/snd device to the container. Provided a file called ping.wav (or any format supported by aplay), you can use it as follows:

docker run \
    --rm \
    --device /dev/snd \
    -v `pwd`:/data \
    yanzinetworks/aplay \
    /data/ping.wav

The image uses a user called aplayer internally and arranges for the user to be member of the audio group in order to be allowed to access the audio device.
