Hi Greg,
It's been a few weeks now, and I have a workaround for the problem, although I wish it would resolve completely. Every day I boot up my computer, the problem resurfaces, so I alternate installing the Realtek High Definition Audio driver and the (Windows) High Definition Audio driver and restart my computer. For example, yesterday I reinstalled the Realtek driver, so today I installed the Windows audio driver and restarted, and the audio began working perfectly. At the end of the day I shut down my computer, and the next day I boot it up and the problem comes back, so I install the other driver. It truly seems like a Windows 10 issue now, so if there is anyone that can assist with this problem I'd highly appreciate it.
Thanks,
Monet
