First, look here: https://github.com/smilingthax/alsa-driver_scarlett/commit/7a77707b66ee476dbf2b87c18fde6a2ea4ded1ec?diff=split (This patch is now inside the mainline kernel; I did not write it) If your second-gen has identical controls to the first-gen 18i20, then you would have to simply insert your USB ID there and it would just work. That is, in sound/usb/mixer.c around line 2395, create another 'case' - case USB_ID(0x1235, 0x8201): /* Focusrite Scarlett 18i20 2nd-gen */ And in sound/usb/scarlettmixer.c after line 1226, insert case USB_ID(0x1235, 0x8201): info = &s18i20_info; break; Line numbers might not be 100% identical depending on your kernel version. That should treat your device like a first-gen 18i20, if I didn't miss anything. No guarantee it will work, but it might. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
