I have Win 10 Pro. That is the one that was upgraded and caused the audio loss. Windows support says it is too late to reset. It is version 2004 or nothing. I might suggest you call Microsoft Support at 206-429-6176. After you get out of voicemail jail and get to a warm body, file a complaint and you will be issued a case number. That will give you an opening to keep after them to get a solution. On the initial call, a technician will update all drivers, etc, but will be unable to fix the problem. The case number will give you access to keep some pressure to get a patch. The creators of this mess are the only ones who can fix it. There is no way now to return to the previous version. They are getting daily emails from me and several others that I know of. I don't know what else to do. I wish you luck. let me know if you make any progress. OK?
Thank you.
