Hi everyone,
Please forgive me if this is not the right place for this kind of
request for help, but i've sent this same message to the bluez-users
mailing list two weeks ago and got no reply, so that's why i'm
retrying on bluez-devel this time.
I'm new to both lists, so please bear with me if i'm not exposing my problem
the right way, and let me know how to improve myself ;-)
I've recently got my hands on a Plantronics M2500 headset and i'm trying to
make it work on my laptop (HP Compaq nc8230).
* I'm running debian unstable with a stock 2.6.22 kernel:
$ uname -a
Linux phugues 2.6.22-1-686 #1 SMP Mon Jul 23 13:23:02 UTC 2007 i686 GNU/Linux
* I'm using sbc & plugz from CVS.
* My /etc/asound.conf file contains the following:
pcm.headset {
@args [BDADDR TIMEOUT]
# The Bluetooth device address for target headset, used for Audio Gateway (PC) initiated connections
# Please note that this value is ignored when the connection is Headset initiated
@args.BDADDR {
type string
default "00:03:89:64:73:40"
}
# This value represents how long we will try to reach the headset, until we give up.
# Value is in milliseconds
@args.TIMEOUT {
type integer
default 6000
}
type sco
bdaddr $BDADDR
timeout $TIMEOUT
}
ctl.headset {
type sco
}
# Simplest a2dpd possible
pcm.a2dpdsimple {
type a2dpd
}
# More complex a2dpd, not yet recommended but worth a try!
# This entry allows the plugin to appear in mixer applications
# This way, the sound level can be controlled by software outside the player
# This worked very well last time! 2007-jun
pcm.a2dpd {
type plug
slave.pcm "a2dpdsoftvol"
}
pcm.a2dpdsoftvol {
type softvol
slave {
pcm "a2dpdplug"
}
control {
name "Bluetooth Headset"
card 0
count 1
}
}
pcm.a2dpdplug {
type a2dpd
}
* I've started a2dpd using the following command:
$ sudo a2dpd --verbose --debug

* i've also started headsetd with:
$ sudo headsetd -n
headsetd[20822]: Bluetooth headset daemon version 0.5
* then when i'm trying to send a WAV file to my headset with:
phugues$ aplay -D headset /usr/share/wengophone/sounds/ringin.wav
i get the following answer:
Playing WAVE '/usr/share/wengophone/sounds/ringin.wav' : Signed 16 bit Little Endian, Rate 11025 Hz, Mono
Warning: rate is not accurate (requested = 11025Hz, got = 8000Hz)
please, try the plug plugin (-Dplug:headset)

i also get the following traces from headsetd

headsetd[20822]: Nobody uses SCO channel anymore, closing it.

My questions are the following:
- is there something i'm doing the wrong way ?
- if not, what does the "please upgrade your Kernel !" message really mean ?
I doubt that my kernel my be not current enough, but maybe i should compile/install some
additional module in it ?!
I thought that a2dpd did not need any kernel module added contrary to the btsco, but
perhaps i was wrong ?
Any help or advice would be greatly welcome.
Thanks in advance.
