[Pkg-bluetooth-maintainers] Bug#588259: bluez: Repeated key problem with Sennheiser headset PXC 310 BT and MM 100

[Christoph Karg]

Package: bluez
Version: 4.66-1
Severity: normal

Hello,

first of all a big "Thank You" to the Debian team for their effort on providing such a great 
GNU/Linux distribution. 

Here is the problem, I am dealing for some days. I tried to connect the bluetooth headphone 
Sennheiser PXC 310 BT to my laptop. Using pulse-audio and blueman, anything worked right off 
the box. The only problem are the buttons of the headphone. The buttons are recognized 
correctly, but I get too many key presses. For instance, if the "Forward" button is pressed 
once on the headphone, usually more than 10 XF86AudioNext events are created. The same problem 
occurs, if a Sennheiser MM100 bluetooth headset is used. Both headsets work flawlessly with 
Windows 7 and my android phone. I tried to manipulate the keyboard repeat rate via xset and the 
KDE settings, without any success. Also the usage of an alternative linux kernel did not help.

Any ideas on hunting down this bug?

Thanks,
Christoph
