I have a cheap old bluetooth headset that worked great with my Q9c. Now I want to use it with the DX for podcast. It paired and connected just fine. And I can make phone call with it. However, it won't play any media audio (Google Listen, Pandora, etc.). In bluetooth setting the device is connected to phone audio. Does it need to be connected to something like "media audio"? Is it just the limitation of my BT headset or I can work around it by tweaking a setting on the phone? Thanks!
