I have wanted this capability for quite some time. The Roku Media Player can display images or play audio, but not both at the same time.
I recently added a soundbar to my TV setup that can receive audio over bluetooth. Now I can display images using Roku Media Player while streaming music to the soundbar from a phone or tablet.
