I've been having an issue with audio on my system. When watching certain videos (I've only seen this on YouTube), the sound cuts out intermittently. After a lot of experimentation, I've discovered that it only happens on videos where speech is interrupted with moments of complete silence. At the beginning I hear, "Please understand that there is a huge difference [ ] TES5Edit merge patch [ ] merging mods. Merge patch is a patch that is created [ ] records..." and so on. It is always the first word after a pause.
I have found that if I run another video in the background that provides constant sound (like playing a music video in VLC), it doesn't cut the words out. It almost seems as if the sound hardware is going into a 'sleep' mode or turning off when there is complete silence, and it takes a split second to reactivate when sound starts again, cutting off the first word.
I've tried every troubleshooting technique related to software that I could find: enabling and disabling hardware acceleration for the browser, disabling Flash, trying three different browsers.
I discovered that it plays fine if I plug in my USB headphones, bypassing the NVIDIA hardware entirely.
My current setup looks like this: video card ---> HDMI cable ---> HDMI splitter ---> TV ---> sound system (no, I don't have a receiver, and can't afford one.) It works beautifully for anything that doesn't have complete silence.
I've also tried switching out the HDMI cable, using a DisplayPort cable, bypassing the HDMI splitter, and using a different HDMI plug on the TV. None makes any difference.
It seems really likely at this point that the culprit is the card itself, or a setting for the card, and some sort of low-power/sleep feature seems likely, too. Any help would be appreciated.
