/dev/dspx should be an oss device like /dev/dsp0.
In the old version of BlueZ there was a plugin called snd-bt-sco and 
created an entry under /proc/asounds/cards.

With that the oss emulation created a dsp-device of the alsa device. But 
the wiki tells that this is no longer needed.

I use a 2.6.26 kernel with "ALSA for SoC audio support" (I know SoC is 
not ScO, I think this is not what I'm need).

My problem is now, that I can't use the aoss command cause there is no 
card entry for the headset and so no /dev/dspx will be created.

I searched around the internet but find nothing about it. So I don't 
know if it a mistake from my side or bluez does not have such a feature.

The man page of aoss told me that I can "fake" such e device with
"pcm.dsp0 {      type plug      slave.pcm "headset" }"
in ~/.asoundrc.
But this will not work, there is no such routing to the bluetooth device.

Manuel
