How to Test CN059/AU002
root@imx8mpevk:~# cat /proc/asound/cards
0 [audiohdmi ]: audio-hdmi - audio-hdmi
audio-hdmi
1 [Device ]: USB-Audio - USB Advanced Audio Device
C-Media Electronics Inc. USB Advanced Audio Device at usb-xhci-hcd.1.auto-1.4.4
CN059/AU002 recored
root@imx8mpevk:~# arecord -Dhw:1,0 -d 5 -f cd -r 44100 test.wav
Recording WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
CN059/AU002 play
root@imx8mpevk:~# aplay -Dhw:1,0 -f cd -r 44100 test.wav
Playing WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
CN059/AU002邊錄邊放測試
1.註冊聲卡使用pactl list sinks 和pactl list sources來查詢
2.指定聲卡來源pacmd set-default-source 1 (Microphone)
3.指定聲卡sink來源pacmd set-default-sink 0 (C-Media)
4.測試Line In時 : 需要先去修改source #1 Active Port為analog-input-linein，命令如下：
- pacmd set-source-port alsa_input.usb-C-Media_Electronics_Inc._USB_Advanced_Audio_Device-00.analog-stereo analog-input-linein
測試Mic In時：要先修改source #1 Active Port為analog-input-mic(Default)，命令如下：
- pacmd set-source-port alsa_input.usb-C-Media_Electronics_Inc._USB_Advanced_Audio_Device-00.analog-stereo analog-input-mic
5.邊錄邊播放指令
- arecord –Dhw:1,0 –d 5 –f cd –r 44100 | aplay –Dhw:1,0 –r44100
