Re: Focusrite Scarlett 18i20 2nd Gen mixer driver

Re: Focusrite Scarlett 18i20 2nd Gen mixer driver

I'm assuming the .h file has just the single snd_scarlett_gen2_controls_create function for now.

Re: Focusrite Scarlett 18i20 2nd Gen mixer driver

Re: Focusrite Clarett USB

I've returned the Clarett in favor of getting a Scarlett 18i8.

Re: Focusrite Scarlett 18i20 2nd Gen mixer driver

Looks like I can't send PM's yet, I have and 18i8 and I'd be happy to help. Should be pretty similar with limited dimensionality on the output matrix.
