TLV320AIC3104: TLV320AIC3104 can't record and aplay

Part Number:TLV320AIC3104

Hello

 I am using linux4.19 kernel, chip is tlv320aic3104, and then the menuconfig configuration <*> Texas Instruments TLV320AIC3x CODECs, my device tree configuration when the audio input, I can control the output from bypass to RIHGHT_LOP/M. What I want to achieve is a configuration with red differential inputs, and green differential outputs. But when I execute arecord -D hw:0,0 -f S16_LE -d 10 -c 2 -r 16 -t wav 001.wav, the audio doesn't output from the i2s to the cpu, play the audio aplay sin.wav sound comes out from the cpu, But I'm not sure it made it into the 3104 chip. When using linux4.1 before, configuring audio was able to achieve what I needed, I couldn't achieve it using the same configuration.

 

I hope to achieve my needs through alsa command and ask for your help.

Best Regards

 

Note 1: I noticed a change in the numid number between the old version of the alsa command and the new version. For example:

numid=42,iface=MIXER,name='Right Line1L Mux'、numid=43,iface=MIXER,name='RightLine1RMux'

Note 2: My command to configure the recording is

amixer cset numid=32,iface=MIXER,name='PGA Capture Switch' on,of

amixer cset numid=31,iface=MIXER,name='PGA Capture Volume' 31,31

amixer cset numid=23,iface=MIXER,name='AGC Switch' off,off

amixer cset numid=40,iface=MIXER,name='Left Line1L Mux' 2

amixer cset numid=44,iface=MIXER,name='Left PGA Mixer Line1L Switch' on

amixer cset numid=37,iface=MIXER,name='Left HPCOM Mux'

好的,谢谢。我之前没有注意到发送的是中文论坛。
