There is high frequency background noise in the audio of A129 Duo/Pro if i use HK3 ACC Hardwire Kit.
If i use normal USB cable with car charger then audio is much better.

Video with A129 Duo with HK3 and A129 Pro with car charger.

Yes, they say that newer version of hardwire kit fixes this issue.

I purchased my camera and hardwire kit end of May/early June and it does it. I didn't nitice it at first because I suffer from tinnitus and have a high pitched ringing in my ears all the time.

Looks like the high frequency noise comes from a camera unit itself.
