Hi I've installed bluez 4.9 and linux kernel 2.6.27-rc7 and I still cannot get any sound out of my Jabra JX10 bluetooth headset connected via a Cambridge Silicon Radio Bluetooth Dongle (0a12:0001). Bluetoothd says "connect: Operation not permitted" and aplay "Unable to install hw params". What should I try next? I think that I'm missing something stupid. thanks for any help (or requests for more information) Stuart PS BTW, if use bluez 4.4 & linux 2.6.26, aplay works, if I use bluez 4.7 and linux 2.6.26, aplay fails.
