ISSUES AND IMPROVEMENTS

RA00 version - FULL
(UC20)

• http://192.168.2.206/mediawiki/index.php/XMED0030HardwareRABugs

Audio in

Lite

Configure audio line in:

amixer -c 0 sset 'Analog Right AUXR' cap
amixer -c 0 sset 'Analog Left AUXL' cap

Then you can easily record:

 arecord -t wav -c 2 -r 44100 -f S16_LE -v audio-in.wav

Finally, listen audio recorded:

 aplay audio-in.wav

FULL: PMIC MIC IN

Configure mic in and line out (to test):

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

Then you can easily record:

 arecord -t wav -c 2 -r 44100 -f S16_LE -v audio-in.wav

Finally, listen audio recorded:

 aplay audio-in.wav

Audio out

audio out jack

Configure audio out:

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

Then you can easily play a *.wav sound with the application Aplay, for example:

aplay audio-in.wav

audio out onboard speaker

Configure audio out:

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 

Then you can easily play a *.wav sound with the application Aplay, for example:

aplay audio-in.wav
