Audioengine B2 repair. Left channel low volume and scratching noise
« on: July 29, 2020, 11:11:06 pm »
I'm working on repairing a Bluetooth amplifier board and am reaching out for help. One of the two audio channels is almost inaudible and has inconstant scratch noise independent of volume nob. Line input is affected the same way. What could be wrong?
