From c032044e9672408c534d64a6df2b1ba14449e948 Mon Sep 17 00:00:00 2001 From: Cyan Nyan Date: Tue, 3 Sep 2024 19:52:29 +0900 Subject: ALSA: usb-audio: Add quirk for RME Digiface USB Add trivial support for audio streaming on the RME Digiface USB. Binds only to the first interface to allow userspace to directly drive the complex I/O and matrix mixer controls.
