1/14/2022 - The Windows level 2 tech found 2 updates located in the Advanced Options on the Windows update window. These updates are for the wi-fi and bluetooth drivers. After a restart, all of the applications affected by the audio issues are now working properly. Hope this helps.
1/15/2022 - 10:00am Well, this morning - less than 24 hours later - after the updates - we are back to square one. The delay is back on all programs needing audio/video playback. Back to contacting Microsoft.
1/15/2022 - 4:00pm - After an exhaustive day with MS I was transferred to Dell support. They were not able to fix the problem, so the end result was to reinstall Windows 10. All audio/video issues are now resolved. The lesson learned from this is to wait a year before updating to a new operating system. Sorry I could not give you better news.
Ok Norma, thanks a lot for feedback. I will stay this way with Windows 11. When these guys have it resolved in a main update, I´ll let you know after several weeks of using it.
