The noise only appears when the engine is running. No noise at all if I only turn on the power. It can be loud sometimes, and sometimes it disappears(mostly during winter)...I have waited for like 7 months but no response from Mazda official(My dealer said they have reported this issue) yet...Does anyone have this issue?

A guy in dealer said it's my dashcam is interfering, but I have unplugged every extra electronic but the noise still exists.

I have never heard this kind of noise...Need help...

Here is my record of the noise:

Noise starts from 10-sec mark. The startup music is just my dashcam.
