Interference on audio?

[Kirkofski]

I downloaded a video from my camera this morning after I came across an incident and there seems to be some interference that wasn't on my earlier video's;

Todays;

Older;

The only things that have changed are;

1) the camera has been in and out of the mount around 10 times since the first video.
2) it was -3deg C this morning.

Has anyone come across similar interference.

Make, model and firmware version?

 

[Kirkofski]

Its the Mini 0801 with 20131202 firmware.

There are newer firmware versions, assuming its a genuine one although I can't say this problem is typical

Did you buy from a reliable source?

Yes I got it from Eprance off Amazon.

Its been running the same firmware for the last 6 weeks and the I've not encountered any interference before(I've downloaded at least 1 video per week)

Hardware problem maybe

I downloaded a few recent videos today and the interference has gone. I'm hoping it was just down the temperature that morning.
