Simulation error

Hello there!

I have the following circuit:

When I try to simulate it I receive the error: "Error in DC-Solve - Aborting non-finite value"

What does this mean? And how can this be fixed?

Okay as far as R5. The wiring of OA1 and OA2 is all wrong, and the floating node at OA2 + input is causing the dc solve error. The LM358 is a low power opamp, may I suggest that you find an audio power amplifier ic to drive the speaker? Hope this helps, mike
