Hi,
I’m using the herelink to transmit audio to a speaker on our drone. However the input volume of the microphone is quite low. I’ve also tested with a external microphone with the same low input volume (it is much lower compared to when i use it with my laptop).
From what I’ve gathered so far is that the volume of the microphone is limited by default in android with no possibility as a user to change it.
How can I fix this issue?
Is it possible to gain root access?
Thanks
