Here.
You can't set the Sennheiser as default? If its "Ready" that normally says its available and can be set.
The only thing that changes when I click it is "Show Disabled Devices", "Show Disconnected Devices", and "Properties".
The only other thing I can think of is a complete uninstall, both the device and drivers. Start over.
Go to the Device Manager and RIGHT click on the Entry for the device and then LEFT click "Uninstall". Also uninstall drivers.
Disconnect the device and then restart the PC.
After Windows has started, do a new install following the manufacturers instructions (usually install drivers first and only connect it when the driver install tells you or after the driver install has finished). Usually, on device installs, if you connect the device first either the install will fail or incorrect drivers can be installed.
The only thing I can think of is, once again check and verify the connections and cables on the motherboard and tower.
