+Subject: [PATCH] audioadapter: perform setup again after a PortConfig
+
+After the ports are reconfigured, we need to perform the setup again so
+that buffers and processing can happen with the right settings.
+
+This fixes an issue when autoswitching between A2DP and HFP with
+bluetooth headsets when there is also a stereo capture device available.
+The input stream of the browser is quickly reconfigured between stereo
+and mono with only a Pause command in between, clearing the setup state
+is enough to redo the setup when going back to Playing.
+
+Fixes #2764

+When we try to play data but the ringbuffer is full, we need to start
+the device or else we will stay in this situation forever and stay
