An alsa lib, that works over OSS drivers ?

An alsa lib, that works over OSS drivers ?

[David Balazic]

Hi!

I have this idea that migh accelerate the adoption of ALSA.

It is a library ( dynamic ) that implements the ALSA API ( so to
applications it looks like
normal ALSA ), but accesses the hardware over OSS drivers. Like this :

app <--ALSA-API--> this_library <-- OSS-API--> OSS driver <---> sound
hardware

This means that application writers can write to ALSA API and be assured
that their
code will work on both ALSA and OSS systems.

The only thing needed is to install this new library on the OSS system ( the
ALSA systems
will off course work as they are ).

This new library would have the same name and API as the existing alsa
library.

How does this sound ? Feasible ?

Thanks for any reply,
David Balazic

AFAIK, such a project already exists. I don't have the url at hand. A 
google search should help.

It's enough to write OSS plugin to alsa-lib.

Can't be done that way.  That is why there is an OSS
wrapper for alsa.  The OSS drivers do not support
all of the capabilities that ALSA drivers do.

So now there's one person saying it can't be done, and another saying
it has been done.  There seems to be slight contradiction here.

They were both replying to the same message, so I assumed they were
referring to the same idea.  I must have missed something.
