    Hi Mitesh,

    What changed from the point it was working earlier?These errors pop up if the audio-routing is messed. Did you change any dapm related settings or anything on the device tree settings?

    We can get on a call tomorrow morning (Dallas Time) and debug the issue.

    Thanks,

    Suren

    Hi Suren, thanks for your time today. As you said, I tested all the signals and clocks and there was disconnect on the DIN and DOUT and hence the speakers were not working. 

    all back to working now.

    Thanks a lot.
