I keep randomly losing sound on my workstation, and it's driving me nuts.

Self built PC in early 2016 (building PCs since the '80's, so this ain't my first rodeo lol) and relevant-to-the-discussion components are a Gigabyte GA-990FX-Gaming mainboard (introduced Jan 2016) feeding into a soundbar+subwoofer via mb optical out and an XFX Radeon R9 380 feeding into a Seiki 4K (2nd gen) via HDMI.

Sound drivers as listed in Dev Mgr. are:

1. AMD High Def Audio Device (Catalyst ver. 15.8 ...not fond of current AMD drivers & control center, tho' have tried - via removal/uninstall/reinstall/new install - about every AMD offered driver version for the R9's).

2. Realtek High Def Audio (driver v6.0.1.7889, 18 Jul 2016 ...fresh update, supposedly W10x64 Anniversary edition version)

I only use the optical out feed on the mainboard to the soundbar. Optical out provides good sound to the soundbar/woofer, and the speakers on the Seiki obviously aren't in the same league so I never use the HDMI feed to the Seiki's speakers. (Why would I lol?)

If I delete the AMD audio driver, it will come back on restart or scan. It's presence or lack thereof doesn't matter, really though, because sound-through-optical can work fine whether the AMD driver is disabled, enabled, or deleted.

The issue: Windows 10 randomly "loses" all sound. Dunno why. It just does. No rhyme nor reason. It's working fine ...until it's not. Lather. Rinse. Repeat.

It's not after [all] patches. It's not a driver problem. It's just some random "tic" in Win 10 that surfaces on the odd occasion.

Again. When sound is working, it works just fine.

To get sound back, I might end up futzing for several minutes to a couple of hours, and ...sound starts working. Sometimes because of one thing, sometimes another (i.e., in connections, or restarts, or power cycles, or settings ...and/or some combo of events???).

WTF.

I'm soo tired of this. And yeah, it just happened again, and I thought I'd throw it out on the TH forum to see if it's a familiar issue to anyone.

(Googling has not been productive ...my madd search skillz are up to it, but search results aren't ...generally ...helpful ...too many non-relevant, general-purpose threads to wade through.)

Anyone?

 
If you're audio on all device's is nullified then this is the first I'm reading of it otherwise it's common occurrence with any system that is powered by a Realtek Audio chip being run under Microsoft's Windows 10 platform.

I must ask though, have you made sure your BIOS is up to date? Have you made sure that the default audio output device is, in Sound Manager, set to the optical output? Is the same issue being seen with drivers sourced from Realtek's download site?

Last effort would be to try a repair install.
