I thought so and of course disconnected the Bassme. Didn't help. Seems more like activating the Tactile ouput can cause the problem? My very first test with the Bassme i connected it to the HP B output jack on the front and had no such problems. Either it has something to do with activating the Tactile output, which I didn't before or playing around in the Listening room settings while listening to this Room at the same time. Don't know yet.
