Re: No sound on headset

hello again
I have compiled linux-2.6.22...with all support needed for Bluez...
Now when i again try to play asong to my headset using

[Pramod@localhost src]$ mplayer_install/bin/mplayer -ao alsa:device=headset 1.mp3
The popup comes on system when i enter "0000" the application waits and connects to
headset. One beep is heard on headset...After that system hangs with the monitor all white..

As system is hanged i cant see the /var/log/messages nor the hcidump...
Someone please help me this...

You 
should 
at 
least 
use 
a 
modern 
kernel 
for 
the 
best 
chance 
at 
getting 
this 
to 
work. 
The 
current 
version 
is 
something 
like 
2.6.24 
last 
time 
I 
looked, 
so 
2.6.15 
is 
very 
old 
and 
possibly 
vulnerable 
to 
a 
number 
root 
exploits 
if 
not 
patched.


-> 
After 
this 
one 
beep 
is 
being 
listened..
-> 
What 
may 
be 
the 
reason 
for 
this 
???

There's 
not 
enough 
info 
here 
for 
me 
to 
tell. 
Try 
running 
the 
daemons 
in 
debug 
in 
the 
forground 
(hcid, 
sdpd). 
Maybe 
run 
hcidump 
during 
the 
time 
you 
try 
as 
well.


-> 
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.....?

Just 
download 
the 
latest 
kernel.. 
Build, 
install.
