Hi, I recently purchased the Bluetooth Audio Pack for Go Pro. I have it installed the back on my Go Pro Hero 4 - everything seems normal. I have paired it to my 20S headset, after turning the pack on, it automatically connects to he headset and I can hear the prompt "Go Pro audio pack connected" in my speakers. 

When I start recording video on my Go Pro, only the audio from the built in mic is recorded and my voice is very faint in the background. If I disable the on board mic and only record my voice in the helmet - it records, but also very faint and low in volume. 

Is it possible to adjust the volume of the voice recorded by the back and to make it louder somehow? 

Thanks.
