how can I turn 
up 
the

sound? can you just give me some hint?
Shall I really try Btsco way?
Else I replace my BT adapter?? But I have three. Two are Broadcom and one is silicon wave.
Only one is working to the maximum is the current one which is broadcom.
Which one shall I try now?
Sorry for too many Ques???
Have a nice time ahead.

Thanks and Best regards 
Pramod

That's

press

then 
it 
does 
the

That's 
odd. 
Never

like 
that 
before...

According 
to 
the 
Gentoo 
Wiki, 
your 
HS 
does 
work 
with 
modern 
kernel/bluez. 
BTW, 
last 
time 
when 
everything 
looked 
right 
but 
you 
didn't 
hear 
anything, 
did 
you 
remember 
to 
turn 
up 
the 
alsa 
sound? 
When 
I 
reboot, 
alsa 
is 
always 
set 
to 
0.. 
I 
use 
rexima/aumix 
to 
turn 
up 
the 
volumn. 
That's 
a 
common 
oversight. 
Other 
than 
that, 
I 
really 
don't 
know 
why 
it's 
working.

-> 
As 
you 
said 
there 
might 
be 
a 
incompatibility 
issues 
in 
one 
of 
them(HS/dongle)

The 
headset 
seems 
OK, 
from 
the 
wiki. 
You 
might 
look 
up 
the 
dongle, 
if 
you 
didn't 
already.


-> 
Can 
it 
happen 
that 
I 
might 
require 
to 
play 
the 
audio 
with 
certain 
frequency, 
rate 
or 
parameters 
which 
are 
supported 
by 
my 
HS(Its 
a 
Sony 
Ericsson 
HBH-602)?

Not 
totally 
sure, 
but 
mine 
didn't 
require 
them. 
I'm 
assuming 
it 
used 
the 
defaults 
in 
that 
case.
