This is patch loader for EMU10K1 (EMU10K2) for ALSA.
This disables AC3 passthrough on SB Live.

There are two parts:
Server - ld10k1 - running as service - it is storing driver state - it must run
under root or by setuided
Client - lo10k1 - controls server and dump loader dl10k1 - loads dumps
previously created with lo10k1 & ld10k1.

ld10k1 will clear card DSP program and you will hear nothing.
You must load some patches to route sound from inputs to outputs (use
audigy_init script for audigy 1, 2 or init_live for sb live).
After loading patch check and set oss mixer emulation through proc file
(/proc/asound/card/oss_mixer)

In directory setup are some patches which I use on my Audigy for testing.
With this you will have exactly same mixer as with original driver (+headphone
control, not tested AudigyDrive inputs and outputs, AC3 passthrough).
Use as10k1 compiler from alsa-tools package to compile patches.
