Can't get A2DP to stick with bluetooth headphones

view story

http://forums.fedoraforum.org – I am new to Fedora with a fresh install of Fedora 11 x86_64. I am thrilled that I have my stereo bluetooth headphones working. They worked great in Ubuntu Hardy, but the dist-upgrade to Intrepid broke something and I haven't heard a peep out of them since. The only problem I have is that I can't get anything but monaural telephony. When they are turned on I can go into Sound Preferences and there is a drop-down showing a choice of High Fidelity Playback (A2DP) or Telephony Duplex (HSP/HFP). By default every time I open Sound Preferences they are set to Telephony Duplex. If I change it to A2DP it doesn't stick. There is only a Close button on the Sound Preferences window, no "OK" or "Apply" button. I never use these headphones for anything but music, so I want them to be always A2DP. My .asoundrc file says: pcm.bluetooth { type bluetooth device 00:1A:80:4E:84:BE profile "auto" } I've searched the forums and googled, but I haven't found the secret yet. Can anyone tell me how to get them working always as A2DP? (HowTos)
