Sound problems - 12 channel remote....

Where to start......

......this Build Blog is about the up's and down's, and here's a down post.....

Well, I'd missed crimping an earth connection lead in the eyelet socket, so that explained why one channel didn't play. So redid the wiring into a new eyelet, only to find it wasn't the right size hole (a rouge size). So had to re-do .........again, third time lucky?

Before I found the missing earth crimp.

Then, all this time testing for sound and not getting anywhere fast, only to find that the remote channel I thought was no1, was in fact no7, (these come with no instructions mind). Am still having issues with actually setting up the remote, as one minute it works (you can hear the relays click) and plays when buttons are pressed, the next some don't??

Another 3 hrs of waisted effort last night, out of the 12 channels, I have 4 channels that will play sound, because the relays or the remote/board programme? And 2 channels that are for some reason repeats of two of the 4 channels?? And there not even connected up???

Conclusion:

• Either the 12 channel board is faulty.
• My soldering defo needs improving [this goes without saying lol]
• There's a problem with the Audio FX board [not likely as test triggers all the sounds]
