Playing 2 audio sources simultaneously topic

Is it possible to stream 2 completely different audio sources via different outputs, as an example:
1 via the Bluetooth headphones and 1 via the 3 mm headphones jack.

On the same subject, is it possible to play same audio source via 2 outputs.
Same song can be heard on the Bluetooth headset and from the 3mm headphone jack/phone speaker?
