Hello, can you see if there is audio at the exit of the jungle? The volume output is through pin 6 on LA76931.

You don't have to use a signal follower, or an oscilloscope.

Hello, I put you above the jungle volume output, there is no diagram. It would be necessary to see if another brand uses the same chassis that not if it is the one that you put, it seems to me a rare number for chassis model.

Did you use a signal follower to track the audio?

You are going to have to make one is easy, because otherwise you need an oscilloscope. I search the web as a follower of audio signals and you will get a few easy to do.

that such a friend could already solve the problem of the fault was a resistance of 720 ohm of the mute that blocked the audio the audio follower helped me a lot thanks for your collaboration friend
