Sorry for that massive first post – but figured the more info the better 😛
Just a quick update on this – I tried plugging in an old laptop via VGA with a 3.55 from the headphone jack to AV3 in and….
No Apu humming bird sounds. 🙂
I’m guessing it was just the VGA cable – still I would be interested to hear any suggestions. (I’m still new to the OSSC, might of missed something simple)
Also, I have a ton of other retro consoles w/scart cables from RGC.uk if anybody would like me to test anything 🙂
