Since i currently don't have a working soundcard in my Sam460ex I once again tried to get the SM502 drivers to work.
in the Kicklayout it does load the Siliconmotion502.chip and the file exists in the kickstart folder. I ahve copied the SM502.audio file to the DEVS:AHI folder and the SM502 file to the DEVS:AudioModes folder
still it will not show up in the AHI prefs.
Any one more out there had these issues?
Should the Ranger show something more than SM502 display controller under PCI bus?
Also. Why cant we have the source for the SM502 driver so that we can help out in improving the driver?

Sources or not... I'm willing to try hacking for my own audio driver if nothing happens before I get hands on with a sam460 to pair with the sam440 I am currently buying

Yeah. There are sources out there for the SM501 and specs are yeasy to get for both. Maybe we should set up a framework for writing drivers and then figure out the rest.

If you can't get it to work, I think its likely some thing is wrong whit the hardware but you can always check whit Ross first, maybe Max can comment on your problem as well.
If its under warranty you should find this out as quickly as you can.

There are some code available to get you started, if your going to try make some drivers, check out my CW MK4 source code on OS4Depot.net, it can be useful if your porting from Linux wrote a few wrappers if I remember correct.
So you have already made a foundation for drivers. Great. I'll have a look at that for more supported soundcards.
Maybe there is some hardware failure but its not a big issue if I use a soundcard. If I need working sound on the 460 I most likely buy a new one. ACube needs all the money they can get. :)

Well I don't have any code for Interrupts, but every thing else is there how to access a PCI card on PCI interface @ Expedition.library, how to identify the card, how push get bytes to and from the PCI card.

I'm also interested in whatever I can learn towards creating device drivers as well.
Especially if there is skeleton examples to work from for various device types.
Can a group of us work together for making a skeleton setup with various link library routines for supporting new drivers to make things easier generally?
is that even a worthy idea?

Drives under Linux and AmigaOS are rally different, but API to access PCI expedition is not that different, maybe its possible to make some Linux wrapper for IOCTL stuff, to make easier to compile Linux stuff, but don't know if its worth it.
Sure! I'm patient but there is other cards out there that needs drivers. We might be on to something here and Nuts might hold the key. Great work. I will check it out. I know what we really need and that is a developer environment that can handle CVS.
I tried the git python kind of thing but I'm used to work with fx. eclipse .
Imagine Codebench with CVS capability so that stupid/lazy coders like myself can develop more easily.
