Hi,

Interfacing TLV320AIC3254 with beaglebone black. Unable to play .wav with aplay. Below are my configurations, please let me know where i am going wrong.

Kernel : 4.1
Rootfs : Debian

Clock source TLV320AIC3254 : Externel 24Mhz

Hi,

Besides the device tree, there are some codec specific & machine layer configurations you need to do.
Check the audio dac example, procedure is explained there: processors.wiki.ti.com/.../Sitara_Linux_Audio_DAC_Example

Best Regards,
Yordan

Hi Yordan,

Thanks for the info. I am failing in defining regulators for TLV320AIC32X4 driver in Device tree, it requires ldoin, iov, dv, av. Following is the errors coming in dmesg.

[ 16.607195] 2-0018 supply iov not found, using dummy regulator
[ OK ] Started Update UTMP about System Boot/Shutdown.

Now i am able to detect the card.
