Re: [Bluez-users] pairing plantronics M3000 with my laptop SOLVED

[Laurent Lesage <laurent@lesagepono.be>]

Hi Brad,

In fact, it works.... something to do with reboot... A service to=20
restart??? I just restarted the computer, after a small reboot with XP=20
to use the headset for Skype :-(. Just "modeprobed" snd_bt_sco and=20
emu10k1 and ... the sound was here! I just use /dev/dsp1. XMMS works=20
fine (in mono). just a small (half a second you said?) delay when I use=20
the volume control on xmms. I also used my IAX client, to record=20
parameters for voicemail box : no problem (in fact, that's the only=20
recorder I used on Linux). Used with skype : first "echotest" trial gave=20
horrible recording. Second trial ok (??). After that, ok.

So, I will redo all the trip on another computer and try to describe all=20
the steps for a config like mine. Finally, as often, the job made  by=20
the Debian team is really great. Every tool is easily installed and,=20
thank to the job of  bluez, blue-alsa, it works well.

I don't see if alsa is necessary, because I installed alsa afterwards=20
and continue using OSS in the sound applications. But I don't know if it=20
is integrated in the kernel. As the debian packages are available=20
separately, I suppose it is not, but I'm not sure.

I will try later the project with bluetooth channel and asterisk.

see you soon
