No sound from any sound device.
The sound on my HP Envy Pheonix 810-135qe was working fine yesterday, turn on the machine and there is no sound from any device at this time. I cannot get sound from the monitor speakers, external PC speakers or the headphone jack. Also I cannot see the speakers in the device manager. Would a system restore to a previous date correct the problem? I have performed all the tests that Windows provides, but to no avail. Any help will be greatly appreciated.
