Try it, if you use it as a non-inverting buffer, you should be OK


can you tell me more clear abour non-inverting please ! thank

Wire the op-amp with a connection DIRECTLY from the output to the - input connection, wire the audio input straight to the + input.

You'll have to sort out the supply biasing yourself, if you haven't got a negative power rail,
