Audio Test
Before the test, you need to prepare an audio card (ROM-EG57), a microphone and a pair of headphones. The test and jumper setup environment is as shown in the following picture.
1、Record
Take Card ID 0 as an example:
Change CARD_ID=0 according "Get the Audio board ID".
# cat /proc/asound/cards 0 [rockchiprt5640c]: rockchip_rt5640 - rockchip,rt5640-codec rockchip,rt5640-codec 1 [rockchiphdmi0 ]: rockchip-hdmi0 - rockchip-hdmi0 rockchip-hdmi0 # CARD_ID=0 # amixer -c $CARD_ID cset name='DAI select' '1:1|2:2' && \ amixer -c $CARD_ID cset name='RECMIXL BST1 Switch' 1 && \ amixer -c $CARD_ID cset name='RECMIXR BST1 Switch' 1 && \ amixer -c $CARD_ID cset name='RECMIXL BST2 Switch' 0 && \ amixer -c $CARD_ID cset name='RECMIXR BST2 Switch' 0 && \ amixer -c $CARD_ID cset name='Stereo ADC1 Mux' 'ADC' && \ amixer -c $CARD_ID cset name='Stereo ADC MIXL ADC1 Switch' 1 && \ amixer -c $CARD_ID cset name='Stereo ADC MIXR ADC1 Switch' 1 && \ amixer -c $CARD_ID cset name='Stereo ADC MIXL ADC2 Switch' 0 && \ amixer -c $CARD_ID cset name='Stereo ADC MIXR ADC2 Switch' 0 && \ amixer -c $CARD_ID cset name='ADC Capture Switch' 1 1 && \ amixer -c $CARD_ID cset name='ADC Capture Volume' 50% && \ amixer -c $CARD_ID cset name='ADC Boost Gain' 1 1 && \ amixer -c $CARD_ID cset name='IN Capture Volume' 17 17 && \ amixer -c $CARD_ID cset name='IN1 Boost' 3 && \ amixer -c $CARD_ID cset name='IN2 Boost' 3 && \ amixer -c $CARD_ID cset name='IN3 Boost' 3
2、Record
Take Card ID 0 for example：
# arecord -Dplughw:$CARD_ID,0 -f S16_LE -r 16000 -d 10 -t wav test.wav
3、Playback
Take Card ID 0 as an example:
Change CARD_ID=0 according "Get the Audio board ID".
# CARD_ID=0 # aplay -Dplughw:$CARD_ID,0 -t wav test.wav
