Mobius B Lens audio problems

[Gurkha9]

As you can hear from this video, the B Lens Mobius I received recently has something wrong with the audio circuit or maybe the PCB board (scratchy audio). This occurs even if outside the car using internal battery so it's not interference within the car from something else. Besides, an A Lens that I have works fine using the same USB cable, car adapter and SD card (all vendor supplied from eletoponline365). Things sometimes get even worse like at the 2:20 mark. It is using FW 0.59, but came with 0.47.

firmware version on each?

Both are now running 0.59 which is the latest as of today. Step 2 is apparently around the corner.
Funny thing is the B Lens came with 0.47 and on the first drive (prior to updating) it did not have this issue. May try to downgrade and see if that changes anything.

Did fw 1.13 help at all?
