Unplugging / replugging the audio-device helps but is annoying, I do not think this is the way it should be. Reproducible: Always Steps to Reproduce: 1. connect USB-audio device to the computer 2. wait .... 3. audio device becomes disconnected Actual Results: Audio device needs unplug / replug operation to work again Expected Results: No device disconnection .... -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
