I made an internal audio mixer that levels the CD audio and Amiga audio.
The problem with mixing the two is the power output is extremely uneven. Well, the internal cd-audio that is If you play only the amiga audio, it barly comes out cause the resistance is lesser going towards the cd-drive. But when you play the cd-audio, it so over powers the amiga audio that you can barly hear your "FINISH HIM"s.
So I found and leveled the resitance levels, put a volume control on the CD Audio, and mad the whole thing internal on a card face plate.
I called it the Audio Inny. I was going to make a shell for external use (500, 600, 1200) and call it the Audio Outy.
I showed off the prototype at Amiexpo in Baltimore a year or two ago and got alot of interest but school and lack of funds keeps me from actually polishing and producing it.
If you really want, I could dig out my notes and you can build one your self.

PS- the hacks on aminet and the Mr. Hardware versions don't have any volume controls in the specs......
Or you could just butcher a cheap pair of head phones from the £1 shop, chop the headphones of the end of the lead. Plug them into the headphone socket on the front of the CD player, mix the audio with the amiga audio out of theback of the phono sockets. (Use diodes so you don't backfeed)Then the volume control on the front of the CDplayer is your level adjust for the CD.
Um.. Diodes on an AC audio signal? you would be better off with an optoisolator, I built one to see if I could send an analogue audio signal across a fibre optic.
It worked fine, a bit complex though, and I lost half the dynamic range of the speaker.
