| |
4.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eric Wong <normalperson@yhbt.net>
commit 2f80b2958abe5658000d5ad9b45a36ecf879666e upstream.
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.
