+Subject: [PATCH] Allow sample rate pass through on Linux.
+
+Requiring the native output sample rate to avoid glitching appears
+to have just been an issue with a poor tlength choice.  xians and
+I resolved this prior to turning PulseAudio on by default, but left
+the native sample rate requirement in at the time.
+
+Since "native sample rate" can change on the fly with PulseAudio
+our approach of specifying FIX_RATE was incorrect.  Allowing Pulse
+to handle resampling lets us remove the FIX_RATE flag.  It also
+improves CPU usage in cases where Pulse can configure the output
+device to match the requested sample rate.
+
+BUG=229918
+TEST=extensive manual checks for glitching.
