pyaudio_test

To test pyaudio in docker.

Find the ALSA card name on your host system

Use aplay -l to list all devices available for playback. The audio card will appear some what like this:

card 2: Generic_1 [HD-Audio Generic], device 0: ALC285 Analog [ALC285 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Copy the card name, in this case its Generic_1.

• clone this repo
• cd pyaudio_test
• docker build -t paulwieland/pyaudio_test .
• docker run -it --rm --device /dev/snd --env ALSA_CARD=<your_card_name> paulwieland/pyaudio_test /bin/sh

Before running the python file, verify once with: aplay Front_Center.wav.

Once at the shell, run aplay Front_Center.wav which should play the audio using alsa. Then run python3 play.py Front_Center.wav which will attempt to play the audio using python.

Play.py is from http://people.csail.mit.edu/hubert/pyaudio/docs/ and plays the audio on macOS.
