Public bug reported: The Dell WD15 Dock incorrectly only has access to the Headphones output of the Thunderbolt / USB3.1c Dock. Users of other distributions have created a workaround profile which works well on my machine (only the directories slightly differ. It would be great if the reason for this issue could be found and either be fixed by this patch or even better by mitigating the original issue.
