Hello, I have recently built the picard using a pi 3 model b. When I play a game on retro pie it doesn’t play any sound. I set the audio to go through the 3.5mm jack in the cmd line as well as in retropie audio settings. When I plug my headphones into the pi I hear nothing and when the aux cord connecting the pi to the speakers is disconnected the speakers emit a low hissing sound.
–Any and all help is greatly appreciated.
