No HDMI Audio

Hi, I am new to BeagleBone. When I connect my BBB to my monitor via HDMI, loud white noise starts as it boots and does not stop.

The speakers are fine, they work with other devices using HDMI.

I have tried a speaker test from terminal, and the white noise becomes quieter during the test but is still apparent.

My resolution is 1980 x 1020. I am running out of the box Angstrom.

Let me know your suggestions.
