Audio DDK documentation

I guess this question is asked often but where do I find the docs
for the Audio DDK? The files I located is 0 bytes.

And also, Is there source for an example driver somewhere?

Thanks in advance,

The package mangler hides it. You can get the real file by descending
into /pkgs/repository/qnx/ddk/… look for ‘deva-doc-xxx’ directory,
there will be ‘bookset.html’ there - just open it in Voyager.

Sources are installed in CVS format, to extract them use ‘get-cvs-src’
script (it has usage message). There are 3 real drivers there (Solo1,
Via686 and AudioPCI) and one ‘template’.

What card are you looking to support?

Thanks Igor,

I want to support cards based on the Maestro-1 chip.
I’m not sure but maybe it is possible to use your Maestro-2 driver
for this chip also?

One way or the other I have to get sound in QNX since I can’t program
without listening to my mp3:s :slight_smile:

Yes, the driver I’m writing would support Maestro 1/2/2E as long as
mixer is AC97 compliant.
I’m about half-way through I think. Will give you alpha copy when get
PCM part working.
