After the latest WD15 dock update there are two bugs:
1. The Dell Dock Update 'Updates Complete' popup continually appears when any device is connected to the dock or the attached XPS 15.
2. All audio is lost whenever any USB device is plugged into either the XPS 15 or the dock itself. Audio continues to play (ie through spotify) but there is no sound. Unplugging the audio jack on the WD15 and reinserting appears to fix this bug.
I have the same problem with respect to the "Updates Complete" pop up. :/ Super annoying.
I have the exact same problem requiring to unplug and replug the audio jack. Very annoying
