bluez-4.69: bluetooth headset stops working

[boba_911]

Hi all, I've updated bluez package to the version 4.69. Now my headset doesn't work. Last version that worked was bluez-4.63. Now when I start mplayer with params "-ao alsa:device=bt_headset", where bt_headset in ~/.asoundrc is:

pcm.bt_headset {
type bluetooth
device 00:07:A4:F2:D9:75
profile "a2dp" #optional, supported profiles are: auto, hifi and voice
}

mplayer hesitate for awhile, and than I see:

[AO_ALSA] alsa-lib: audio/pcm_bluetooth.c:1607:(audioservice_expect) BT_GET_CAPABILITIES failed : Input/output error(5)
[AO_ALSA] Playback open error: Input/output error
Failed to initialize audio driver 'alsa:device=bt_headset'
Could not open/initialize audio device -> no sound.
Audio: no sound

What is wrong?
Best regards,
