Windows 7 update disabled audio
Here's my problem:
Error message: "No Audio Output Device is installed"
Windows 7 was working fine but then after one of its automatic updates the sound stopped working on the system.(i.e. Red "X" on speaker icon)
I have tried enabling the audio in normal, mode safe mode. The driver is up to date and I have even tried re-installing it.
System restore provided a temporary fix as after one normal use of the PC windows will re-disable the audio. (and yes I disabled auto updates....windows still manages to disable the audio)
I had the PC sent out under Manufactures Warranty to try to resolve the issue, but as the warranty only covers physical damage to the system all the service center was able to do was confirm that it was a software problem (they checked the hardware and found it to be working properly).
So I have determined that the audio is solely software related and that it must be disabled deep in the system as the usual enable/disable buttons have no effect.
Any suggestions would be greatly appreciated.
