Sound is conpletely dead

[rsnail_valy]

Hello guys, I have a Xtrons MTCD px5 unit with android 8 on it, I was switching back to the old px3 cpu which I've previously had (the original one, because my px5 cpu is bought), wanted to install the px5 board back in, did it, put all bsck together, switched ignition of the car on, and the unit began to catch smoke, so something fried inside of it, switched back to the px5 board (installed it in the unit) and everything is working fine and normal except the fact that I don't have no sound at all anymore, everything sound related is dead... any solutions, maybe an external sound card if possible? I use the rca's because I have an amplifier in the back.

GA9350b No sound as well

Hey, I have changed my ECU on my E46 and my HU Eonon GA9350b also completely lost the sound. Everything works except the sound. I have updated the MCU, the software, I checked all the wiring and I even replaced it with my old Pioneer and the sound works on it. Does anyone have any idea what it might be?
