From: Eric Wong <normalperson@xxxxxxxx> This patch has been added to the 3.18 stable tree. If you have any objections, please let us know. =============== [ Upstream commit 2f80b2958abe5658000d5ad9b45a36ecf879666e ] 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.
