Title: Piggyback on audio chip?
Post by: AmiBoy on June 10, 2020, 10:23:49 AM
Please forgive an ignorance on the Amigas internal workings/hardware, I was and will probably always be a gamer on the system.

After watching a few videos of the new Warp1260 accel card (which looks amazing -  I really want one), I was made aware of the team looking at producing a scan doubler & flicker fixer card which like a few others (indivision etc) would piggy-back on top of the graphics chip and allow them to pass native displays through the warp 1260 (or act like the indivision and be a standalone) and out through its digital video output (mixing with the RTG).

I really prefer these types of card to anything external as it keeps everything looking nice and neat and seamless inside the case.

Currently I believe their way of passing through native audio is to use a RCA to 3.5mm jack cable and pass input into the card externally with the cable.

However is it possible to capture audio output via piggybacking onto the sound chip, allowing audio to be treated like video with an internal pass-through on the card so that everything is inside the case and seamless looking?

Even if it was possible I know the Warp1260 doesn't have a connection to do this nor does it look like they are going to produce one, I was just very curious about if it could be done in a similar way.

Warp1260 version 2 maybe :-P

Thanks for any replies.

yes. you'll have to provide your own amps and stuff to get it up to line level - but y'know, depends what you want to do with the signal if that's what you want.
pins 30 and 31 are audio Right and Left respectively off the dip package version in the A500/2000/3000/etc. i'd imagine it's probably the same pin number off the plcc version A600/1200/4k/etc
