I now have my A2DP headset working on Gentoo. You just need to emerge the latest version of bluez-utils (3.15) and follow the instructions in http://wiki.bluez.org/wiki/HOWTO/AudioDevices I put device in pairing mode for the Connect call and kbluetooth asked me the pin and then it was ready to work. Now I am using amarok to stream music to my headset. It’s probably to start thinking about getting the 3.X series stable.
It’s already done on x86. There are still a couple of fetch restricted packages in the dependency graph but I think that will be fixed when 6.0 get released and makes it’s way from the overlays to the main tree.
Here is a mail I just sent to gentoo-dev-announce and gentoo-dev
http://bugs.gentoo.org/show_bug.cgi?id=163262 Posting to announce because people might not have been able to use the hooks in their bashrc files because of us using them in our eclasses. Also if you see some weirdness with Java packages this might be the cause although the patch was extensively tested. Regards, Petteri
