+Subject: [PATCH] media-session: only check passthrough when available
+
+When none of the nodes have a valid passthrough format, don't check if
+passthrough is possible.
+
+Without the check, it is possible that a node has a common format with
+the peer that is not a passthrough format, like a raw audio format.
+
+Fixes #1587
