I cannot enable the "windows audio service" at control panel, it appears as a check box, after cheking and restarting the check box appears unchecked.... At services.msc console the "Windows audio service" dont appear anywhere. The audiosrv.dll file is on my HD, but, it's like not exsting. I tried Registry mechanic, error fixer, etc, but not progress. All drivers are installed, already tried wih 2 sound card, the drivers appear installed and working at device manager. Any help will be highly appreciatted.
