Just did the following experiment. Listening to an MP3 file with TCPMP. I have a PPC-6700 and I have a Sony Ericsson HBH-DS970 BT headset. It's streaming to the BT Headset just fine.

So I start File Explorer and run this btaudio.exe (I have not put it into the Start Menu or a button or anything). Playback stops and the Voice Tag application runs then says there are No trained voice tags and then goes to the Voice Speed Dial screen for me to add a voice tag.

Switch back to TCPMP and there is no sound going to the BT headset.

OK so I try running btaudio.exe again hoping that it will re-establish the BT headset audio connection. Same deal. Just starts the Voice Tag application. Never re-establishes the BT audio.

I attempt to reset this by turning off the BT headset then back on. Sometimes this works. This time it doesn't. Instead the phone is hung and I have to reset. Wonderful.

Repeat test. Same results but the BT headset comes back this time and plays that little sound. Except TCPMP does not just start broadcasting to the BT. I have to restart it. Restarting TCPMP now plays through BT.

Hitting the call button on the BT headset does roughly the same thing, stops TCPMP, calls up the Voice Tag thing and never re-establishes the audio stream to BT for TCPMP.

Probably not related but for some reason I cannot tap the X or OK button in the upper right hand corner anymore! For any application! The OK button works but I can't tap it with the stylist. I can tap Start and other areas of the top bar just not the X/OK button.
