Hi,

I'll be doing doing gsoc this year, where I'll rework the audio backend 
of qemu to allow multiple backend instances and multichannel audio. 
This will of course require modifications of the existing audio drivers 
in qemu, so it's probably a good idea to remove drivers that nobody use 
anymore (and probably bug rotten anyway).

Here are the drivers that could go in my opinion:
esd: no longer maintained, last release in 2008, replaced by PulseAudio
fmod: not sure about this one, but apparently it's some no longer 
developed library that's also proprietary.
sdl: is broken 
(http://lists.nongnu.org/archive/html/qemu-devel/2015-05/msg02198.html), 
and we have native drivers for almost all platforms
winwave: DirectSound should be a superior choice on windows (even though 
it's also deprecated)

alsa needed on Linux, oss on BSDs, coreaudio on Mac, dsound on Windows; 
spice and pa are also needed.  wav is probably useful for debugging.

Do you guys have any objections about removing the above mentioned audio 
drivers in the near future?

Thanks,
Zoltan
