Sound Controller Driver for my SaviAudio Audio Hub is suddenly being reported as not signed in Device Manager.
However 'sigverif' shows that it is signed. This sends audio from the computer via USB to the Hub which transmits to my speakers.
I uninstalled all sound and USB drivers and reinstalled. This worked once, now it's not.
Appreciate any help - Thanks!

You need a self-signed certificate.

Microsoft probably have revoked that key on their OS'es because they shouldn't have installed a private key in the first place and later "fixes" didn't remove the private key from pre-existing installation. Later "fixes" only meant that the private key was not in the later driver packages --- but it didn't remove the private key that was already installed.
Nobody here is going to be able to help you because we don't have your rare hardware.
