Microphones with headsets to quiet

Hi,

when I use a headset with my FP5 the other side always tells me that they can barely hear me because I’m to quiet.

There seems to be a prolbem with my FP5 because I testet the following.

  • My Jabra BT-headset is to quiet on my FP5
  • My wired headset with an USB-adapter is to quiet on my FP5
  • My Jabra BT-headset works fine on several other devices
  • My wired headset with an USB-adapter works fine on several other devices

Is there a way to change the volume of external microphones in the software or is the hardware or software broken?

Regards
Andreas
