Short: Sets productivity 4 for fast audio DMA Author: wenzel@unixserv.rz.fh-hannover.de Uploader: wenzel unixserv rz fh-hannover de Type: driver/audio Architecture: m68k-amigaos -- Prod 1.0 - a simple, small hack for gfx board owners -- Have you ever been tired of listening to a sound at the wrong playback rate because the program you used tried to play it with DMA >28 kHz? Well, this might be the solution because I figured out the following: - When the Amiga chipset is currently displaying a productivity screen, even high sampling rates are possible. That's a hardware reason I don't want to explain here. - So when I open a productivity screen on my Picasso-II equipped A3000, the playback works as expected. - BUT: When I close the productivity screen and the Workbench comes to front again, it STILL WORKS! - Obvious reason: The Picasso driver keeps the Amiga display in productivity mode after closing the screen as long as no other non-productivity using the Amiga chipset opens up. - So why not write a program that just opens a productivity screen and closes it again?!? Well, here it is! It opens a full sized (640x400), one plane deep productivity screen, and closes it again immediately, so the mouse pointer should be on its old position after the program exits. If the screen cannot be opened, nothing happens at all :-) Legal stuff ----------- Prod is public domain. The source is included. Use it at your own risk! There shouldn't be any bugs in such a small program but if it crashes, I take no responsibility. It works on my configuration of the Picasso-II board. It may work as well on other revisions of the Picasso drivers or even on other gfx boards but it may, however, have no effect at all. Try it out and please mail what you've found out. Miscellaneous ------------- Have a look at Play16, available on AMINET, too! --- wenzel@unixserv.rz.fh-hannover.de (Thomas Wenzel)
