No Audio Device Installed. in Driver Booster 8 Posted August 18 Did you try the solutions in the post by Cicely. Do you have a restore point on any of the computers for a time before the update issue occurred. Do you have any computers which are not affected by this issue. Did you only update audio drivers, or did you update multiple drivers. If so do you know what other drivers were updated. You are assuming that it is an audio driver issue, but it may be another driver causing the problem.
