RCA CAMBIO - Audio troubleshooting - How I fixed it

I had yesterday the same problem with my RCA CAMBIO Windows 10.  I researched what other ppl have done.  Nobody had the answer.  I was going to reset my tablet, but before I did the following:

1)  I checked in CONTROL PANEL, if any device had a conflict.  (yes, there was an unknown device).  I Uninstalled it.

2)  In Ctrl Panel the Bluetooth had many devices, I disable them.

3)  I deleted my device in Sound.........it was good and not

4)  After deleting my device in sound, I thought that if I checked for new devices the Windows will reinstall any new devices........No!  It installed again the device with conflict......

5) What i did is to installed devices  in Control Panel -> Device manager -> Install legal SW (software)

6) I installed first driver from Intel Speaker (Even though mine was Realtek as I have seen, but my hubby RCA Cambio had Intel).

7)  It didn't function.  Then I downloaded the Realtek drivers and installed them through step 5)

8)  After that in my Control Panel Audio Devices appeared intel and Realtek devices

9)  I didn't get a sound in that moment....But

10)  I check the Sound Icon in the left bottom corner of my table, Selected the playback device and there appeared 2 of them. I selected Speakers (Intel SST AudioDevice (WDM)).....AND NOW MY TABLET HAS SOUND.

Hope my experience is of any help for you!

p.s.  The problem happened after updating windows 10
