I just got a new computer that already had windows 7 installed on it. The first day that I used it everything worked fine. Next day I turn the pc on and I have no sound. There is a red X over the speaker icon in my system tray and it shows I have no audio devices installed (showing both enabled and disabled devices). Troubleshooting detects no problems. However, if I restart the computer, sound will be back like normal. So this is what I have to do everyday to have sound; turn on the computer, let it be on for a few minutes, then restart it for sound to work. Sometimes it takes several restarts for it to work. Any ideas?
