Thread:CircuitCo talk:Audio Cape RevB/Audio Cape instructions/reply (4)

Here is the rest of my notes using Roberts notes:

Audio now works, but levels are low so lets fix that:

amixer set PCM 0dB

amixer set 'Right PGA Mixer Mic3R' on

amixer set 'Left PGA Mixer Mic3L' on

Also to make this persistent across reboots add:

CAPE=BB-BONE-AUDI-02 to:

nano /etc/default/capemgr

Useful tests for audio:

speaker-test -t sin 400

arecord -r 48000 -c 2 -f S16_LE -t wav -vv -d 25 example.wav

aplay example.wav
