Audio - gsalaman/pi_notes GitHub Wiki

To install:

sudo apt-get install python-pyaudio

There may be a conflict between the matrix and the straight audio jack...I'm using a USB dongle to mitigate.

To test:

lsusb

This will list all USB devices the Pi sees...and you should see that USB dongle. To see if the record/play functionality is working, you can:

arecord -l
arecord -D plight:1,0 -d 3 test.wav  
aplay test.wav
