+Subject: [PATCH] context: make driver runnable when we add a runnable node
+
+Explicitly make the driver runnable when we add a runnable node to it.
+
+We have to do this because the runnable node might not be directly linked
+to this driver.
+
+In the case of the echo-canceler, for example, a playback stream
+can be linked to the sink before the echo canceled virtual sink.
+All echo-cancel nodes are added to a source driver, which would not be
+activated because there is no direct path from the playback stream
+to the source river.
+
+Fixes #3145
