I decided to do a little soldering again, and had a shot at this one:

I etched the pcb, wired it up, and no  sound at all. Only thing that happens is that the chip gets hot. Realy hot!! So I checked the pcb for shorts, checked the orientation of caps and chip and checked the PS. Same problem, so I checked it all again. I guess I have checked everything a thousand times now, and I still get nothing.

I was therefor wondering if anyone have built this, and if it worked. I've checked it against the datasheet, and it seems to be ok. Any idea what I can have done wrong?

I've wired things up like this
