    Hello Naresh,

    Which Kernel version are you using? Also, what happens when you try to use aplay to play a wave file?

    Hello,

    When you ran the above command " aplay -c 2 -r 44100 -d 10 file_example_WAV_2MG.wav", do you see any activity on your output clocks? Is it possible to collect the BCLK and FSYNC clock while running the aplay command?

    Regards,

    Hi Krunal ,

    do you see any activity on your output clocks? 

    >> please let me know how to check  (i didnt see anything ) .

    Is it possible to collect the BCLK and FSYNC clock while running the aplay command?  

    >> may i know how to collect BLCK and FSYNC clock 

    Thanks,

    Hello Naresh, 

    You need to physically probe the pins and measure the clocks.

    Hi Bhargav ,

    My Audio interface is MCASP0.

    MCASP0_ACLK -> BCLK

    MCASP0_AFSX -> WCLK

    MCASP0_AXR2 -> DIN

    MCASP0_AXR1 -> DOUT

    Thanks,

    Hello,

    I believe the chan2 teardown timeout warning is expected but I will internally check with our dev team and get back to you. Also, are you able to hear anything on the output side? Have you probed the clock to make sure your FSYNC and BCLK are correct.

    Regards,
    Krunal

    Are you sure about the kernel version?

    Kernel v5.4 doesn't support AM62x.
