Yeah the AY3 is coming in hot at 1vpp per channel, each about double the voltage of consumer audio levels for a mix. For experimenting I'd sum them at the virtual ground of an inverting op amp pair and use that to tone the volume down while at it. you may also want a potentiometer in there, but fixed resistors could do, and regulate volume on your speakers.
