I have a Dell XPS 9310 recently purchased, it was working great till recently there was a windows update that affected the sound drivers. After the update, the sound on VLC takes around 7 seconds to load before I can play anything. I looked up the community topics here and found I had to reset my PC, and I did, around 3 times because every time a windows update happens, the same problem reoccurs.
