Way to save DSP resources on the emu10k1

[James Courtier-Dutton <James@superbug.demon.co.uk>]

Hi,

I have thought of a possible way to save DSP resources on the SB 
Live/Audigy etc.

Instead of having DSP code actually in the emu10k1 source code, have it 
in small user land files on disk.
When the snd-emu10k1 modules is first loaded, it will contain no DSP 
code. When alsa-lib detects an emu10k1 DSP, it would scan the user land 
files, and then present the mixer api/user with a list of switches, to 
enable or disable a feature, then, only the features the user actually 
wants and needs would be loaded into the DSP, and thus save on DSP 
resources.

This would also allow for special extra user designed modules, in much 
the same way that emu-dspmgr works on the oss driver.

Then the user could have an almost unlimited amount of DSP modules to 
choose from, and only be limited by how many modules can be loaded at 
the same time.

I am sure thise sort of feature would also me useful on other sound 
cards that have DSPs on them.

Cheers
James
