--- Comment #2 from Riccardo Robecchi <sephiroth...@hotmail.it> --- I just noticed that the bug seems to trigger if I disable an output. In my case, I have a USB DAC and the GPU's HDMI output; if I disable the latter, the unknown device shows up. It seems then like the device is not removed from the list of the applet and therefore appears like an unknown device. -- You are receiving this mail because: You are watching all bug changes.
