I recently came across this strange issue. audiodg.exe uses up high CPU resources for no apparent reason, even when not playing any music. I'm using Windows 8 (64-bit) on an Acer laptop.
Your help will be greatly appreciated. Thank you!
UPDATE: Forgotten to mention, sometimes music/sound doesn't play for some strange reason.
