how can I turn
up
the
alsa
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

You

you

That's

planning

with

hci_event.c

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.
