SURF PI PROBLEM

[daverave]

my surf pi was working fine until i was putting it into its control box and now im getting very weak low audio in the headphones....ive tried a speaker and the same low volume....maybe i shorted something out when putting in control box....ive scoped the tx and sample pulse and all is working ok but low audio...any idea where the problem might lie ?????

Hi mate, I don't know how to solve your problem as I'm a total noob, but I'm really interested to find out how to connect a set of head phones? I have a headphone Jack but don't know where to.connect it?

Cheers

In Place of the Speaker.

In place of the speaker .... and check wich two contact-pins of your Phonejack are "hot" in combination with your earphone before soldering, otherwise you can remain with "no sound".

ok now as i have found the fault and audio is now normal.

I had a similar problem. Surf worked fine. When I installed it into the Alu-control box -the performance was poor. (sound, etc.)
The problem:
The ground from the Hadphone Jack must not be connected to the housing!!
I have the hadphone Jack installed with a plastic ring.
Now it workes Fine...
