Hi ,

Just got my unit. All controls runs fine. But no sound at jack. Is there any command line to test the sound ?

Thank you.

Hi，

Me, too. My unit has all functions, only can't output sound. I try to figure out the problem. Now I try to replace the PCM512 chip.

Did you have already solved the problem ?

Thx

Hi Jason.

In my case , the problem was the optocoupler (i cant remember now, but i think it is the 6n139) . Replaced and everything worked fine.

Oh, thx for the answer ! I will also check my optocoupler. Your answer is really helpful!
