Although air coupling the demodulated DRM Audio between the receiver speaker / headphone and the microphone input of the Smartphone / Tablet will work to some degree. Likely ambient noise will be introduced causing the decoding to be less than ideal. Holding the smartphone microphone near the demodulated DRM output is a quick way to check the SDC. A direct cable or even a filtered line may be needed to decouple Phone / PC / Receiver noise for a solid MSC and audio decode.
If you use a headphone / microphone multi pole plug (like the diagram below), the decoded DRM audio will automatically route to the Headphone jack, so an Audio Switching App (many available on google play store) can be used to route audio to the main speaker of the phone.

Let us know if you use this in your tests... And how it works...
