Vatech 0 Posted July 12, 2021 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 Share this post Link to post Share on other sites
