From 2f80b2958abe5658000d5ad9b45a36ecf879666e Mon Sep 17 00:00:00 2001 From: Eric Wong Date: Sat, 30 May 2015 09:15:39 +0000 Subject: [PATCH] ALSA: usb-audio: don't try to get Outlaw RR2150 sample rate This quirk allows us to avoid the noisy: current rate 0 is different from the runtime rate message every time playback starts. While USB DAC in the RR2150 supports reading the sample rate, it never returns a sample rate other than zero in my observation with common sample rates.
