Victor's HP All-in-One speakers quit working after he upgraded to Windows 10. Leo says that it could be a software issue, but it could also be that the cable that comes from the speaker itself may have become unseated. Leo says it's more likely that it's a driver issue, though. Victor should try Windows Key + X for the Device Manager and look into the settings for his audio driver and see if there's an X or a triangle with an exclamation mark to indicate a driver failure. Victor says it doesn't show his speakers at all and he can't install the drivers to get it going.
