When the laptop is powered on and I log in there is no sound. If I restart the device the sound will then work. The drivers are current and the test in the properties even shows that sound is coming out. But nothing is. If I log out the next user does not have the same problem, the sound will remain working till the laptop is turned fully off. Once off and then back on the next user will need to restart to get the sound to work. Any ideas, suggestions would be appreciated. I have uninstalled and reinstalled the drivers with the same results.
