Asus TF101 - Audio Jack & Bluetooth at the same time

[Yungoso]

Hi,

With the TuneIn radio app, I'm listening to internet stations, in connecting an asus TF101 with an amplifier in using the audio jack of the tablet.

At the same time, I would like to connect the jambox with Bluetooth, so that the radio plays on both devices: the amplifier and the jambox.

It seems as if this is not possible: only one device at the time seems to work.

Does anyone know how to get them both to work at the same time ?

TIA.
