I'm new to the forums, but I have been reading through other posts and I can't seem to find the solution.
I'm trying to get A/V out working. HDMI works just fine, but this pi will be for my niece and her TV doesn't have any HDMI.
Based on the following diagram my camcorder cable will work using the right audio (red). I have even tested with my multimeter and verified my A/V cable does in fact follow the camcorder SRRT.
While the HDMI is disconnected I have tried the following:
Hold 3 during boot up
Hold 4 during boot up
Tried each RCA plug as video during boot up (just in case)
Removed # from sdtv_mode=2 config.txt
