Computer does not output any audio.
Hi, my brother's pc (which I'm using right now) does not output sound, and says that there is "no audio output device installed", even though I've checked on device manager and the realtek HD audio driver is installed, running, and as far as windows knows, it is updated. I've tried rebooting the driver and service and still nothing. I've ran AVG a couple of times and the outcome is always the same: No viruses and Malwarebytes Antu Malware says the same.
When I log on, Dolby Theatre says that it doesn't have a driver installed and can't run, that may be the source of the problem but I can't find the driver for this* pc!
I'm guessing this is the result of careless web browsing by my brother, since it is not the first time he has had problems with his computer, but this time the situation is more serious than the usual "my pc is slow/I tried changing my facebook appearance and now my internet doesn't work"
Also: Even though this computer is connected to a wi-fi network, the taskbar icon says that it is not connected and that there are wi-fi networks available. But this is a minor problem, since I'm able to access the internet without any problems whatsoever.
*This pc is a Sony Vaio SVE14A1S1EB, running the original Wondows 7 Homepremium 64-bit.
