:shock: That poor IC.
with chemelec's advice, you'd want to connect the ground of the resistor (grey wire on left of pic) to pin 2 of the IC, so you only have one ground coming off of the IC.
Do you have any sort of cap. on the audio input?
this is the schematic that I use
**broken link removed**
works great too.
oh yeah, you have to be sure not to get the IC too hot when you are soldering to it, I'm not sure of the exact soldering time, but you cant keep the soldering iron on there for very long.
