Laptop ->TV via HDMI Adapter - audio static and feedback (1 Viewer)

[Zoroaster Zarathustra]

I've connected my laptop to a TV using an HDMI Adapter.
I am experiencing a audio feedback issue and hearing static and clicking while watching a movie.
OS is Vista, I have tried multiple HDMI cables with filter. Running a ViewSpan software that came with the HD/USB adapter. I was told that I may possibly need to set my audio for HDMI but cannot find where to change the settings
I Muted Microphone, and yet i have issues. the static/clicking is utters when my laptop is doing something. for instances moving mouse, streaming etc....

Could be a bad USB-HDMI. I don't have any first hand experience with them, but I sent one to my niece...pretty sure she already has it...and hasn't called to complain about it.

Any USB-HDMI cord recommendation?
