i understand what you're saying now new guy. thank you for clarifying in chat. what you want is a circuit that can flash the LED at higher volumes rather than having it dim. if that's the case then you can try a setup like the one i showed you yesterday, or you can wait a little while and i will give you 2 complete circuits that should both work. the problem, is that like audioguru said, you're going to get a serious reduction in sound quality. you can fix this by using another 386 that is coupled with your first one.
and for the record, i agree, the 2822 is a good amplifier.
