[alsa-devel] [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.
