[Bluez-users] problem using skype + BT headset, Linux OS

[Laurent@lesagepono.be]

Hi all,

back again with a persistent problem. It seems specific with this 
"assembly" (?) : Linux OS + BT headset + skype. In fact there is no 
problem when I use the headset to listen : the problem is when I use the 
microphone. The first time I set up btsco, and use Skype (or other phone 
client), the micrphone creates a terrible noise. I hangup. I reconnect. 
Generally, this is OK. (don't know why it doesn't work the first time). 
But with skype, the problem appears again. I can place one or two calls, 
then the noise appear and my peer does not hear anything he could 
understand. After that, I often get this error with "btsco -v"

while with hcidump, nothing is visible. I just see the dump of the last 
call:

I remeber someone had a similar problem a few days ago. Any idea? A bug?

thanks

yes, there is a "noisy microphone" bug in our sourceforge list. I 
suspect it's happening somewhere other than btsco (the daemon) and btsco 
(the kernel module)
