Part Number: AM5728
Other Parts Discussed in Thread: TLV320AIC3104, , BEAGLEBOARD-X15
Tool/software: Linux
Hello,
We have a custom board based on AM5728 and we are using Audio codec TLV320AIC3104 with McAsp2 over i2c4.
We are not able to play wav file and getting error "aplay: pcm_write:1940: write error: Input/output error" .
I get "ALSA devices list - No soundcards detected" error during bootup.
The relevant parts of the device tree are:

While booting I am getting logs like:
[ 2.478797] No soundcards found.
[ 8.008647] of_get_named_gpiod_flags: can't parse 'simple-audio-card,hp-det-gpio' property of node '/sound@0[0]'

But I get the following message, after using the aplay command：
root@am57xx-evm:~# aplay -l

when I play Audio using aplay :

Please suggest us some solution/ debug approach on this one.
