Ring out your "M" jumpers... Make sure they are connected.

Looks like everying is shifted down one row. For example R5 on the right side looks like it goes to nothing.

Opamp is backwards too.

You may want to start over. Did you get spare parts?

k, I fixed some problems but now I can't get audio on both channels when I fully plug headphone and IC plugs into the in and out. When I plug the 1/8's half way, I get get audio on one channel but not the left and so on . How do I fix this?

That sounds like mis-wired phone jacks.

I would also go back and do some more work on the bottom of that board. Some of your leads are long enough that you may get shorts when you push it into a case. The insulated wire jumpers have way too much exposed wire - you could potentially short several pads at once.

Finally, get rid of the TI TL0XX chip. They suck - and I mean bad distortion in a CMoy, not just low-quality sound.
