Hi everybody!

Just had my first look at btsco. I compiled the sources from CVS and 
everything seems to be fine as I get a connection with the headset and 
e.g. an event is submitted when I press the dial button.
Anyway, when I try sending a sound either directly to /dev/dsp1 or using 
aplay, a connection is obviously established but the only thing I hear 
is constant noise as long as the connection lasts.

As I've got no idea whether it simply doesn't work with the headset or 
there is another problem I try to post all possible information and 
maybe someone can help. Hope it's not an information overflow. ;)


    * Whether there is a hub between your computer and bluetooth adapter 
(you should avoid this especially if it's a usb 2.0 hub)
It doesn't work either with or withour a hub.


    * Manufacturer and model of headset and bluetooth adapter
SonyEricsson HBH-PV700 and Bluetooth USB Dongle BLUE Buffalo, Model: BB1005

          o If it prints "SCO mapping: HCI" then your adapter should work.
          o If it prints "SCO mapping: PCM" then you might permanently 
change the setting using a command like "pskey mapsco 0" using 
bluez-utils-cvs but this is at your own risk.
          o If it doesn't print either of those, you probably need a 
different bluetooth adapter (preferably "CSR" based)
Seems like it doesn't print either of those...? What exactly is the SCO 
mapping and do I really need another bluetooth adapter?

    * If you have a headset that can do a2dp, try both btsco and a2play 
(the significance is that the latter does not use SCO)
a2dp doesn't seem to work at all - don't know if my headset isn't able 
to do it.

<font size="-1">Hi everybody!<br>
<br>
Just had my first look at btsco. I compiled the sources from CVS and
everything seems to be fine as I get a connection with the headset and
e.g. an event is submitted when I press the dial button.<br>
Anyway, when I try sending a sound either directly to /dev/dsp1 or
using aplay, a connection is obviously established but the only thing I
hear is constant noise as long as the connection lasts.<br>
<br>
As I've got no idea whether it simply doesn't work with the headset or
there is another problem I try to post all possible information and
maybe someone can help. Hope it's not an information overflow. ;)<br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; o If it prints "SCO mapping: HCI" then your adapter should
work.<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; o If it prints "SCO mapping: PCM" then you might permanently
change the setting using a command like "pskey mapsco 0" using
bluez-utils-cvs but this is at your own risk.<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; o If it doesn't print either of those, you probably need a

Seems like it doesn't print either of those...? What exactly is the SCO
mapping and do I really need another bluetooth adapter?<br>
