+Subject: [PATCH] output/PipeWire: call pw_stream_flush() in Cancel()
+
+Clear not only MPD's ring buffer, but also libpipewire's buffers, to
+avoid playing some audio from the previous song after a manual song
+change.
+
+Fixes part 1 of https://github.com/MusicPlayerDaemon/MPD/issues/1354

+Subject: [PATCH] output/PipeWire: after Cancel(), refill buffer before
+ resuming playback
+
+Deactivate the stream in Cancel(). This fixes stuttering after a
+manual song change by refilling the whole ring buffer before
+reactivating the stream.
