If you are saying that the audio out on the HDMI monitor is all noise, and not audio, then there is nothing wrong with your gear. I do not believe the HDMI out signal contains any audio until you are playing a video in the camera.
That's how nearly every Canon DSLR works, and there is work around to fix it. The HDMI output is intended for an external recorder, one with its' own audio inputs and headphone output.
Your camera lacks a headphone output.
