Cause: Destroys / Recreates rendererinstance when other thread(s) are feeding data to it.

Also: Media Type negotiation is based on the device's supported formats. When the device changes the agreed media type may no longer be valid.

Easiest solution: Deny changing of audio device when connected.

Workaround: Stop playback and disconnect filter before changing device.
