9744 'popping'

Post by iOS_Neil »

Hi,

I've been tinkering with a 9744 amp over the past few weeks and plan to mount it inside a case along with my RPi. Everything has been going great and all to plan...Until today. I went out and bought a pair of 4 inch speakers that I figured would look great in the box I'm planning on using. I plugged them in to see how good it would sound and that's when everything went wrong. Upon putting the volume up a little, the speakers just start popping and not running at all well. I figured it was the speakers so I swapped them out for another I've been using during testing - and they're doing it as well (they've always worked just fine before today). I've put a video up here to show the problem: https://youtu.be/kx2QznhPgSc
As I say, until today everything has been working perfectly. I've wired up a pot to the board and that's always worked exactly as it should.

Any ideas what's going on?

Thanks,
Neil.
