+Subject: [PATCH] gst/pwaudiosink: set the default latency time (buffer size)
+ to be 21.3ms
+
+This is to solve underrun issues that seem to appear with the default
+10ms latency that GstBaseAudioSink has.
+Hopefully in the future we will have a better mechanism to pick
+the appropriate latency instead of hardcoding it here.
+
+Upstream-Status: Submitted [https://github.com/PipeWire/pipewire/pull/140]
