some weeks ago I had to exchange an OggStreamer because one channel was not working – the user Mike recorded the following video to demonstrate the problem:
If you watch the video closely you can see that the left channel is always amplifying the Audio with a very high gain – and only as he turns the gain up also the right channel appears – actually it is the right channel that is working correctly and the left has an error where it has a very high gain.
Looking at the schematics reveals that a connection error to the Potentiometer (which is in the Feedback loop) could cause such a high gain of the inverting amplifier:

So a loose connector is my first guess. My second guess would be a faulty potentiometer.
Lets take the device apart:


gently push the whole assembly (top and pcb) out of the extruded alluminium case:

A quick look around and touching cables reveals the problem:

because I had a spare contact lying around i soldered on a new contact, but elsewise I could have recycled the orignial one:

Time to put everything to gether and check if it works:

both channels work now 🙂 success.
