From 74dc71f83e500b2c6bb0d01a947e1b7231456dd8 Mon Sep 17 00:00:00 2001 From: Nobutaka Okabe Date: Fri, 23 Mar 2018 19:20:00 +0900 Subject: [PATCH] ALSA: usb-audio: FIX native DSD support for TEAC UD-501 DAC There are two versions of TEAC UD-501, the normal version and the vendor updated version(UD-501V2). They have the same VID/PID, but the num of the altsetting is different, UD-501 has 2 altsets for stream, and UD-501V2 has 3. So, add the logic to distinguish them by the Product Name, not by the PID.
