Hi,
I have an i7 build with the EX58-UD5 motherboard and am using the on board (realtek HD) sound card. I tried to play a movie in mkv format but was getting no sound. Other formats such as avi work, I also confirmed the mkv had sound by playing it on my laptop. I was wondering if anyone else has had this problem and knows of a driver I need. Oh yeh I am running Windows 7 (64-bit)
Many Thanks
