Other Parts Discussed in Thread: TLV320AIC3104, LM4871
Tool/software: Linux
Hello,
I use beaglebone black and audio cape with TLV320AIC3104 audio codec & LM4871 amp.
but, i make dts file for audio, but there is no sound from the amp when "aplay sound.wav".
Please help me and check my dts file.
Below is my dts file:

Below is my board and audio cape schematic.
Below is my board info.
I think my i2c is strange.
below is my i2c1 when my board boot.
blue line is sda. yellow line is scl
Thanks,
boo
