I am working on imx6 solo custom board.presently working on audio sgtl5000 .

I have changed the dts file for iomux settings and sgtl5000 related settings.

Sgtl5000 is registered ,i can confirm it through aplay -l command. But when i play the file sound does not come.only some junk sound comes always when i connect the headphone.

Please suggest what is the issue,is am missing configuartion

Thanks and Regards

Hi Rizwan

one can test with oscilloscope mclk sgtl5000 signal.

Please check its settings (CLKO1 pad) using BD boards configurations,

for example imx6qdl-sabrelite.dtsi

linux-imx6/imx6qdl-sabrelite.dtsi at boundary-imx_4.1.15_1.0.0_ga · boundarydevices/linux-imx6 · GitHub

Schematic with sgtl5000 connections can be found on

i.MX6 ARM Development Board

Hi Rizwan

what about bit clock and frame sygnal. What procesor used in the case.

Had you tried with baremetal SDK:
