=== Audio in ===
==== Lite ====
Configure audio line in:
<pre>amixer -c 0 sset 'Analog Right AUXR' cap
amixer -c 0 sset 'Analog Left AUXL' cap</pre>
Then you can easily record:
<pre> arecord -t wav -c 2 -r 44100 -f S16_LE -v audio-in.wav</pre>
Finally, listen audio recorded:
<pre> aplay audio-in.wav</pre>
==== FULL: PMIC MIC IN====
Configure mic in and line out (to test):
<pre>amixer set -D hw:0 'Analog' 100%
amixer -c 0 sset 'Analog Right AUXR' nocap
amixer -c 0 sset 'Analog Left AUXL' nocap
amixer -c 0 sset 'Analog Left Main Mic' cap
amixer -c 0 sset 'Analog Right Sub Mic' cap
amixer set -D hw:0 'Headset' 0dB
amixer set -D hw:0 'HeadsetL Mixer AudioL2' on
amixer set -D hw:0 'HeadsetR Mixer AudioR2' on</pre>
Then you can easily record:
<pre> arecord -t wav -c 2 -r 44100 -f S16_LE -v audio-in.wav</pre>
Finally, listen audio recorded:
<pre> aplay audio-in.wav</pre>
=== Audio out ===
==== audio out jack====
Configure audio out:
<pre>amixer set -D hw:0 'Headset' 0dB
amixer set -D hw:0 'HeadsetL Mixer AudioL2' on
amixer set -D hw:0 'HeadsetR Mixer AudioR2' on</pre>
Then you can easily play a *.wav sound with the application Aplay, for example:
<pre>aplay audio-in.wav</pre>
==== audio out onboard speaker ====
Configure audio out:
<pre>amixer set -D hw:0 'Headset' 100%
amixer set -D hw:0 'HeadsetL Mixer AudioL2' on
amixer set -D hw:0 'HeadsetR Mixer AudioR2' on
echo out > /sys/class/gpio/gpio82/direction
echo 1 > /sys/class/gpio/gpio82/value </pre>
Then you can easily play a *.wav sound with the application Aplay, for example:
<pre>aplay audio-in.wav</pre>
=== audio codec Cirrus Logic CS53L30 ===
<pre>root@igep00x0:~# i2cdetect -r 3
WARNING! This program can confuse your I2C bus, cause data loss and worse!
