From 9f35a31283775e6f6af73fb2c95c686a4c0acac7 Mon Sep 17 00:00:00 2001 From: Alexander Tsoy Date: Thu, 13 Feb 2020 02:54:50 +0300 Subject: ALSA: usb-audio: Add clock validity quirk for Denon MC7000/MCX8000 It should be safe to ignore clock validity check result if the following conditions are met: - only one single sample rate is supported; - the terminal is directly connected to the clock source; - the clock type is internal. This is to deal with some Denon DJ controllers that always reports that clock is invalid.
