That my last desktop with a realtik HD Audio is not using the realtek at all when I connect with HDMI and send audio over HDMI. I recall I disabled that in the BIOS and still got sound over HDMI. Confusing but since sound is all digital, I would not be looking at Realtek.
But the way drivers hook in like that, plus you solved it I won't disagree with the fix.
Windows has a long history of us having to turn things on and off to fix stuff. This has lead to some leaving Windows forever.
I have 2 desktop computers running 64 bit Windows 10, connected to a 3 way A/V switch to select which signal I would like to send to a 32in. flat screen and a set of speakers.
Both computers have the Realtec High Definition Audio but different motherboards.
Well after the last big MS update the audio on both computers has been cutting in and out and I thought it couldn't possibly be the comps as they are pretty new (you guys helped me build them) , Device Manager said everything was working fine on both .
Ran Ubuntu and everything was fine.
Booted Windows back up and ran the Troubleshooter on the Realtek High Def Audio and it came up with "Disable Enhancements".....So I disabled them even though no enhancements were being used on both and I be damned if it didn't fix it on both computers.
Now , That's what's bugging me here,
How can I have to disable enhancements on 2 different computers in Realtec Audio after the Windows update, especially since I don't have Windows install drivers , so what's the connection here ?
