How do I go about playing 2 different mp3 files from two different USB sound cards? The mp3 files are stored locally and I would like to use python script to choose a file and play it on one of the two sound cards?

I found through some browsing over the internet about pulseaudio. If I install pulseaudio and create two sinks ,one USB sound card each, will I be able to select a sink and play a file choosing a sink from python? What package/library would I need in python to interface with pulseaudio sinks?

Thanks!

  • is this possible with pymad and pyaudio together? – hansen dsouza May 21 '14 at 17:06

You could try using a python library that simply may execute terminal commands and then use pactl to upload an audio sample via pactl upload-sample FILENAME [NAME] and playback via pactl play-sample ID SINK.

Be sure the python process is run by a user that can control pulseaudio, and is part of the groups audio, pulse, and pulse-rt
