I've got 2.6.24 with bluez libs/utils 3.25 I have successfully paired my headset and PC, I can l2ping it and get info. As soon as I try to play some audio (via mplayer) I get the following in the logs: audio[21835]: Registered manager path:/org/bluez/audio audio[21835]: Loading device 00:05:A1:08:00:B1 (headset ) audio[21835]: Got path /org/bluez/hci0 for adapter with address 00:18:F3:8D:AF:67 audio[21835]: Selecting default device audio[21835]: Setting 00:05:A1:08:00:B1 as default device audio[21835]: Accepted new client connection on unix socket (fd=9) audio[21835]: Audio API: received BT_GETCAPABILITIES_REQ audio[21835]: Audio API: sending BT_GETCAPABILITIES_RSP audio[21835]: Audio API: received BT_SETCONFIGURATION_REQ audio[21835]: config sbc - frequency = 0 channel_mode = 0 allocation = 0 subbands = 0 blocks = 0 bitpool = 0 audio[21835]: State changed /org/bluez/audio/device0: HEADSET_STATE_DISCONNECTED -> HEADSET_STATE_CONNECT_IN_PROGRESS NetworkManager: [1203182486.201530] nm_hal_device_added(): New device added (hal udi is '/org/freedesktop/Hal/devices/bluetooth_acl_5a10800b1'). hcid[21832]: link_key_request (sba=00:18:F3:8D:A3:67, dba=00:05:A1:08:00:B1) audio[21835]: /org/bluez/audio/device0: Connecting to 00:05:A1:08:00:B1 channel 1 audio[21835]: State changed /org/bluez/audio/device0: HEADSET_STATE_CONNECT_IN_PROGRESS -> HEADSET_STATE_CONNECTED audio[21835]: /org/bluez/audio/device0: Connected to 00:05:A1:08:00:B1 audio[21835]: State changed /org/bluez/audio/device0: HEADSET_STATE_CONNECTED -> HEADSET_STATE_PLAY_IN_PROGRESS NetworkManager: [1203182489.924061] nm_hal_device_added(): New device added (hal udi is '/org/freedesktop/Hal/devices/bluetooth_acl_ffffffffffffffff'). hci_scodata_packet: hci0 SCO packet for unknown connection handle 45 hci_scodata_packet: hci0 SCO packet for unknown connection handle 45 hci_scodata_packet: hci0 SCO packet for unknown connection handle 45 ........ force_scofix=1 doesn't help.
