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
