Media Audio Port: ASoC: no backend DAIs enabled for Media Audio Port - Error

New Contributor I


I am getting this every time I reboot my board. What might be the possible cause? How to fix it? For reference I attached the reboot info. I highlighted some text. Are they normal?


Reboot Log:

Hello arunkumark,

Thank you for interest in the Intel® Edison Breakout Board.

I experienced something similar a while ago, what I did to solve the issue was flash the firmware with the manual process (

Then I changed the standard USB port that I was using to power the breakout board for a higher power USB port (usually marked with a lightning symbol).

The recommended method to power the board is with a wall adapter power adapter, so if the issue persists, please consider doing that.

Please let me know if the issue persists after trying the previous suggestion.

If you need further assistance, don't hesitate to contact us.
