7.14.3 Playback
Run speaker-test to check playback availability:
target:~$ speaker-test -c 2 -t wav
To playback simple audio streams, you can use aplay. For example to play the ALSA test sounds:
target:~$ aplay /usr/share/sounds/alsa/*
To playback other formats like mp3 for example, you can use Gstreamer:
target:~$ gst-launch-1.0 playbin uri=file:/path/to/file.mp3
If Speaker volume it too low you can increase its volume with (values 0-3):
target:~$ amixer -c 0 sset Class-D 3
Hint
Speaker output is only mono so when stereo track is played only left channel will be played by speaker.
7.14.4 Capture
arecord is a command-line tool for capturing audio streams which use Line In as the default input source.
target:~$ arecord -t wav -c 2 -r 44100 -f S16_LE test.wav
Hint
Since playback and capture share hardware interfaces, it is not possible to use dierent sampling rates
and formats for simultaneous playback and capture operations.

7.15 Audio on phyBOARD-Nash
Warning
Due to HW bug Audio is broken on phyBOARD-Nash i.MX 93 PCB revision: 1616.0
To use audio with phyBOARD-Nash an additional adapter for the Audio/Video connector is needed. The
PEB-AV-10 (1531.1 revision) can be bought separately to the Kit. PEB-AV-10 is populated with a TI
TLV320AIC3007 audio codec. Audio support is done via the I2S interface and controlled via I2C.
There is a 3.5mm headset jack with OMTP standard and an 8-pin header to connect audio devices with the
AV-Connector. The 8-pin header contains a mono speaker, headphones, and line-in signals.
To check if your soundcard driver is loaded correctly and what the device is called, type for playback devices:
