ALSA: usb-audio: add the initial mix for Presonus Studio 1824c
A reasonable initial mix for the 1824c is the one that Presonus Universal Control calls bypass. It mutes all the physical inputs, and connects Daw channel 1 to Line out channel 1 (left) Daw channel 2 to Line out channel 2 (right) Daw channel 3 to Line out channel 3 (left) etc. To get the most out of the 1824c a mixer application like Universal Control is needed. One is available for linux Link: https://github.com/royvegard/baton Signed-off-by: Roy Vegard Ovesen <roy.vegard.ovesen@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
