Is it possible on the Note 10.1 to keep the Internal Speakers on while simultaneously having sound from a device which is plugged into the 3.5mm headphone jack socket? I have a small, battery-portable Bass Rich speaker (Wowee One) which I think would work very well as a sub-woofer, together with the Note 10.1 internal stereo speakers, for both Music and Video Sound. As people seem to have had this happen, in error, as a "problem" on various other Android devices, it would seem that it should be possible for an App to control the Internal/External sound in this way. I have looked at lots of Apps - particularly those controlling headphone buttons - but nothing which does just this. Does anyone know of a way?
