Playit 1.69 - problems on Cortex A8

Hi folks!

Rick Hudson’s PlayIt is supposed to be platform neutral at 1.69 (Andre Timmermans site) but I’ve run into problems on CortexA8 despite it appearing on the compatibility list. Basically, if one uses the Acorn16bit sound driver (only one supplied), and does a *playit_play I get an Abort after a couple of seconds. I’m guessing this may be hinting at alignment exception problems.

I suspect Andre’s DiskSample stuff will do a similar job, but playit has queuing features which I can’t see in DiskSample.

Has anyone had any experience of this?

Hmm! The Cortex A8 compatibility list refers to !PlayIt 1.68 on Rick Hudson’s site, in a “Seems OK” sort of way.

Hosted on my site is an upgrade to that by Christopher Martin also versioned at 1.69. I cannot comment on its ARMini compatibility.

Is there more than one 1.69 out there?

I just tried 1.68 to no avail either :(

Neither version will play a WAV file here. 1.68 aborts at &2768 in the PlayIt module. 1.69 did not abort but it didn’t play either.

Rick Hudson has kindly sent me the source code to PlayIt – it is written in BASIC assembler.

As you guys probably know, I code in C, so am out of my depth with this. Is there anyone around who feels willing/able to assist? Obviously I’d be willing to show my gratitude for this :)

The goal would be to release a new PlayIt with source included, so that future updates can be done more easily.

Thanks,

Hi Andrew,
I’ll put out a request for help on RISCOScode.
Regards,
Martin.

Just a quick follow-up… Willi Theiss has been looking into PlayIt for OMAP4, and I’ve sent him the source that Rick supplied me with. Apparently he has it working on his Panda, but I get silence on OMAP3, so we’re making progress. This all happened in the last 24 hours!

I’ll keep everyone posted, but thanks to everyone so far :)
