Audio
Step 1: Check audio codec
Card 0 is IMX digital array audio, Card 1 is sgtl5000 audio , Card 2 is HDMI audio
# cat /proc/asound/cards 0 [imxaudiomicfil ]: imx-audio-micfi - imx-audio-micfil imx-audio-micfil 1 [sgtl5000]: sgtl5000 - sgtl5000 sgtl5000 2 [audiohdmi]: audio-hdmi - audio-hdmi audio-hdmi
Audio codec（sgtl5000）
1. Set MIC and headphone:
# amixer -c1 set Mic 32% Simple mixer control 'Mic',0 Capabilities: volume volume-joined Playback channels: Mono Capture channels: Mono Limits: 0 - 3 Mono: 1 [33%] [20.00dB] # amixer -c1 set Lineout 100% Simple mixer control 'Lineout',0 Capabilities: pvolume Playback channels: Front Left - Front Right Limits: Playback 0 - 31 Mono: Front Left: Playback 31 [100%] [0.00dB] Front Right: Playback 31 [100%] [0.00dB] # amixer -c1 set PCM 100% Simple mixer control 'PCM',0 Capabilities: pvolume Playback channels: Front Left - Front Right Limits: Playback 0 - 192 Mono: Front Left: Playback 192 [100%] Front Right: Playback 192 [100%]
2. sgtl5000 Record and Playback:
# arecord -Dplughw:1,0 -t wav -d 5 -c 2 -V stereo audio-luyin.wav # aplay -Dplughw:1,0 audio-luyin.wav
HDMI Playback
# arecord -Dplughw:1,0 -t wav -d 5 -c 2 -V stereo audio-luyin.wav # aplay -Dplughw:2,0 audio-luyin.wav
Mic array Record and playback
Step 1：Check audio codec
# cat /proc/asound/cards 0 [imxaudiomicfil ]: imx-audio-micfi - imx-audio-micfil imx-audio-micfil 1 [sgtl5000]: sgtl5000 - sgtl5000 sgtl5000 2 [audiohdmi]: audio-hdmi - audio-hdmi audio-hdmi
Step 2：Record with mic array and Playback with HDMI
# arecord -Dplughw:0,0 -t wav -d 5 -c 2 -V stereo mic-array-luyin.wav # aplay -Dplughw:2,0 mic-array-luyin.wav
