I had this problem with 2 computers that I upgraded with cloned MX500 drives. Both are about 9 years old. One an HP notebook, the other a desktop with an ASUS P6T motherboard. Both are running WIN 10. Here are the steps I eventually tried to fix the problem in WIN 10. 1. DO NOT download any drivers. 2. Open Device Manager ( press windows button and X. Select Device Manager) 3. If you have the above problem, there is no SOUND, VIDEO and GAME CONTROLLERS in the device list. 4. Expand 'System Device' and search for a sound device that is in error. Hopefully you locate this. 5. Right Click and select 'PROPERTIES'. 6. Select 'DRIVER' tab. 7. Select 'Update Driver'. 8. Select 'Browse my computer for driver software' 9. Select 'Let me pick from list of available drivers on my computer'. 10. It should quickly return with a list of drivers. 11. Select your sound card driver and complete whatever prompts appear. 12. Within seconds your missing 'SOUND, VIDEO and GAME CONTROLLERS' should appear and the speaker in tray (bottom right) will now be functional. Hope that works as it did for me.
