OpenAL - ALSA interface proposal. I request for comments...

[Manuel Jander]

Hi,

Since there is almost nothing else to do to support the Aureal Vortex 
3D processor on Linux, just as i announced some time ago i started
designing a OpenAL interface for ALSA. The design is meant to be
applicable to other hardware too.

I made a preliminary description, from what i have done so far, because
i want to allow other more experienced people to comment and give input
to this.

I posted it in plain text. I hope that is compatible enough.

Well, please give it a read, and tell what do you think about. Thank you
very much.

Best Regards

i think this is not a very good idea. if you want to wrap OpenAL
around ALSA, then wrap it around alsa-lib. don't go messing with the
kernel API, that just doesn't make any sense.

but more importantly, i don't see how any of what you are proposing
aids the use of the aureal vortex 3d processor. a device driver isn't
a library, its code that writes data to registers and handles
interrupts. nothing about OpenAL deals with that side of things.

It does not seem like you have read much about alsa. The interface 
between alsa-kernel and alsa-lib is liable to change at any point 
whereas the alsa-lib to application api might change, but will always 
ABI compatible.

If there are features of a sound card that you cannot access via 
alsa-lib, just find ways to add them to alsa-lib first. Everything 
needed on the hardware should be accessible via alsa-lib.

Cheers
James
