Any suggestions for op-amps using the sound command

[jessey]

Hello,

Would anyone know of a good op-amp that would offer reasonable amplification and volume control for a pic chip? I've been playing around with the sound command and have a small 8 ohm speaker connected to a LM386N-1 amplifier and it gives a surprisingly good sound but I can't seem to get any kind of volume control. I found the schematics for the 386 in an old Radio Shack book and wired it as per their instructions, I've included the schematics here if someone could have a look and possibly offer any solutions to get the volume control working.

If anyone knows of a good op-amp that's proven to work well with the pic chips sound command then I'd surely appreciate any information that could be provided.

Thanks
jessey
