Q: Windows 10 Sound Not Working.
I finally was able to successfully install Windows 10 on My iMac Late 2011 21.5 inch. Everything is working fine, the keyboard and everything, BUT THERE IS NO SOUND, yes, I have installed the latest Boot Camp Drivers to my USB and repaired/installed them multiple times, YES, I have the latest OSX right now, what else can I do this is very frustrating everytime I press the volume buttons they give me Circle with a line thru it symbol and I can't do anything about it, Please help, I will provide any information necessary.
iMac, OS X El Capitan (10.11.6)

You 2011 Mac does not officially support Windows 10. However, you can upgrade from W7/W8.1 to W10. It preserves the BIOS/MBR installation that is necessary for Sound to work.
Please also see No Sound after installing windows 10 on MBP 2012 .
