hi All
I want to play audio from my system on my BT headset..
I am able connect to it, pair it, but when i run command
[Pramod@localhost ~]$ mplayer_install/bin/mplayer -ao alsa:device=headset 1.mp3
It gives one beep and waits for few seconds and again comes out with this error.....

[AO_ALSA] alsa-lib: pcm_sco.c:277:(sco_headset_hw_params) Unable to set number of SCO buffers : please upgrade your Kernel !
[AO_ALSA] Unable to set hw-parameters: Invalid argument
Could not open/initialize audio device -> no sound.
Audio: no sound
Video: no video

After this one beep is being listened..
What may be the reason for this ???
I tried adding patch from plugs from Bluez CVS....But its not compatible  with my kernel
2.6.15 fedoraCore-5....
Which patch i should add for upgrading my kernel....?
I also tried installing BlueZ 3.25(libs and utils)...but no change...
Can anyone help me please..????
Thanks in advance....
Pramod
