Want to listen to MP3 files with Pocket Tunes over the original headset but the internal speaker does not mute and no sound comes through the headset. When I do a call, the headset works correctely and Pocket Tunes goes mute. I have the same problem when I put the Treo in the THB Bury car kit. No sound on the car loudspeakers and the Treo speaker goes mute only when I do a call.
Anybody experienced this before?
