    No sound after Windows 10 Update




      I have just had an automatic update on Windows 10. After the update there was no sound from my laptop although everything else seems to work. My laptop has a message advising that "No audio output device is installed"


      I have restarted my machine but this doesn't have any impact.


      When I check the Sound Control Panel it states that "No output nor input devices are found".


      However, when I check the devices its states that there is an Intel (R) Display Audio and advises that it is working properly. It also states that there is an Intel High Definition Audio however it advises that "The drives for this device are not installed (28) and that there are no compatible drivers for this device. When I try to update the driver it states that Windows cannot find a driver for this device?


      I'd appreciate any assistance and advice to help me get sound back on my device.
