Hello,
this is my first post in this forum.
I will use a TinkerBoard ( Rev1.2) to implement an IoT device.
Everything was ready and i connected the board with a Class D amplifier via the 3.5mm jack.
I configured the Headphones as output (3.5mm jack) but the volume is incredibly low.
i connected the amplifier to a laptop, a pc and a smartphone using the same cable and everything was ok.
I checked the sound settings, they were at 100db and i had the volume on Max.
Am i missing something?
Is it because of poor preamp on board? Any suggestions?
Thank you in advance
