I'm using version 0.9.10, on Ubuntu 8.10

I have module-volume-restore enabled in the config, but it doesn't stop the
reverting behaviour. Even hitting stop and then play on the streaming
application is enough to have the stream reverted to the default sink.

I had noticed module-stream-restore was introduced in 0.9.11, but i figured
this sort of feature would have existed in earlier versions as well.
