+Subject: bluetooth: Amend writeout to send more initial frames
+
+When bluetooth transport has both both sink and source, pulseaudio would
+synchronize writing out frames with reading frames from peer to make fair
+schedule of reads and writes. Pulseaudio allows two blocks of data to be sent to
+peer before synchronizing writes with reads just in case that peer implements
+similar write schedule.
+
+It could happen that first blocks are still missed by peer, which would cause
+pulseaudio writes to stall waiting for first frames from peer.
+
+Fix this by allowing more data frames out until data from peer is actually
+received.
+
+Closes: https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/issues/1424
+Part-of: <https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/merge_requests/777>
