First, sorry for not posting about gbtsco and Ubuntu Hardy or answering your comments.
As some of you may know I wrote a software called gbtsco a while ago (feisty or gutsy) that was acting as a frontend to a binary (btsco) which connected to alsa’s snd-bt-sco to connect to a Bluetooth headset.
With Hardy, btsco is now officially deprecated upstream and alsa’s own implementation of it is to be preferred. To have my Logitech headset to work with Ubuntu, all I had to do was to create a .asoundrc file in my home directory with the following content :
Then put my headset into pairing mode and start a software (twinkle in my case) and select the Bluetooth soundcard in the settings. I hope that we’ll soon have a way to do that graphically (ideally through the gnome-bluetooth applet).
I won’t continue working on gbtsco as it doesn’t have much work to do now and I don’t myself have the time to make it work with .asoundrc. I do really hope to see an upstream effort in implementing that in gnome-bluetooth or any other easy to use configuration tool.
