I wouldn't say it has nothing to do with drivers since it is completely useless without them. I know some people used sound card DACs with Spaghetti and had a ton of success. I know of some others who never could get it to work. The drivers make or break the experience. Hopefully, you are adding the capability to have full ILDA output voltages +-10V. You should consider clamping the outputs so that they can't overdrive the laser and amps. I know that adds complexity to the correction amp but not too much.
