Recently purchased Plantronics BB903+ headset to use with TP. Can not figure out why some apps can be heard and some apps can't be heard. Talking about Iheart, tunein, and internet radio. I get sound in the headset from my Pre using tunein. I don't when I switch to TP tunein. The headset says connected, but no sound. Iheart, same thing. Internet radio, same thing. I can listen on the Pre, but not on the HP.

Am I doing something wrong or is there something I don't know?

HP Movie Store plays through the headset with no problems.

Thanks
