LX v7 vario won't play audio sound

[[email protected]]

The audio function is stopped working mid flight. I went to the volume screen and adjusted the volume up all the way, still no sound. I then powered it off, back on, hoping to reset it with no luck.

After I landed, I unplugged each wire going to the V7 and re plugged it back in. All connections look good. The speaker works fine still as its shared with the radio.

Any troubleshooting advice is welcomed here.

Thanks,

SA

Scott,

How did you connect the speakers? Series or parallel. It is important depending on the connection you may have overdriven the amp. Please see this link for an explanation.

Using the same speaker for the radio and the vario is very unusual, as
they are usually intended to use their own speakers. Is that connection
shown in the wiring diagrams for the vario and/or the radio? If it
isn't, then it's possible the improper connection has damaged the vario
speaker output.

Putting the outputs of two amplifiers together is not a good idea.
Saw it done with two 2000W professional amplifiers last week, they worked again when the short was removed.
