Hi, there. I think I already know the answer to this but I'm hoping I'm wrong. All of a sudden I have no sound on my laptop. My HP Pavilion just stopped making sounds and says I have no audio devices installed. Please don't tell me that I have to replace the sound card! I get so nervous when I have to work on these little guts. I replaced the fan in my ASUS mini notebook and I had to pull out everything to get to it. Well, let me know. I can take it!
