+Subject: [PATCH] gst/pwaudioringbuffer: wait only for STREAM_STATE_CONFIGURE
+ when starting
+
+The CONFIGURE state is reached when the pw_client_node is exported,
+while the READY state requires the session manager to try and link
+the stream. If the SM does not want to link the stream due to policy,
+the client should not hang there forever.
+
+Upstream-Status: Submitted [https://github.com/PipeWire/pipewire/pull/140]
