No sound with Minecraft

I've read others post this problem and then the thread is locked before a solution is given. Bottom line, Minecraft does not load the information on the screen when it first starts and there is no sound in the game if Norton Family (not premium) is running on that profile. If I disable NF then everything works great immediately. What's the fix? Machine is Windows 7 and everything else, Norton Family, Java, Minecraft, etc., literally everything is the most recent version, updated today. This seems to be a known issue between NF and some Java programs and I would like to know the fix if there actually is one. Thank you.
