So... after the 50 or something re-plug of the speaker, it suddenly works.... Don't know why but thanks
This would be a bit lengthy since I am trying to give out all the info and attempts I've tried, thank you for your patience in advance!
I have an almost 4-year-old Win 10 msi GE60 (upgraded from Win 7), Win10 ran perfectly and I have always used it to play music through USB speakers. Things all went well until yesterday...

In order to enable virtualization to run duo OS on my GE60, I updated my obsolete BIOS with the Win7 64 files and instructions provided on official support website. Though the new BIOS still did not have virtualization related options, it was enabled and my duo OS ran perfectly.

But then, when I tried to play some music through my USB speakers like what I used to do... nothing came out from the USB speakers after I plugged it in, music still came out from my laptop speakers. I went to "devices and printers" trying to tweak the default device but there was not much I could change. It seems to have something to do with NGIC USB Speaker driver as my "device manager" said the device is not installed. I tried every port on my laptop and manually installed the Realtek HD Audio driver and it did not work either....
