Manage Audio Devices takes a full minutes to open window

[NineLives]

if you go to control panel>hardware and sound>manage audio devices, it takes a minute for it to appear, but last night when I opened it it took less than a second to open. I recently installed mumble, but I opened it last night to stop sounds from my game being lowered when someone was talking. Why does it take 1 minute to open on my desktop and 1 second on my laptop?

help lol.
