I'm scratching my head on this one and have searched and searched but have been unable to find any topic similar to my problem.
My problem is that when using HDMI audio to my TV the sound is really really sketchy. For movies, if I start playing a movie the sounds is extremely distorted. It sounds like someone is blowing into a microphone or there is a jet engine in the background. After anywhere from 5-10 seconds the sound normalizes but it's out of sync with the video. Restarting the video by dragging the playback to the beginning fixes this and everything is right as rain.
However, if I close the video program(this case VLC, or any other video program-it doesn't matter) and reopen any file or even the same file it does the same thing EVERY time. Also, if I'm listening to an mp3 file and open another program, like say chrome to web browse, the sound gets extremely distorted as well. Sometimes it clears up but most times it doesn't unless I close chrome or whatever program.
Games on the other hand just don't work at all. The sound is always distorted. If I were to leave the speakers on my TV turned up I'm afraid they'd blow out because of how awful it sounds. On a rare occasion, sound will play normal for as much as a minute but will always revert back to being super distorted.
I've tried different TVs, different drivers, updating nvidia drivers, downgrading nvidia drivers. Clean windows install. Feels like everything and I'm at my wits end.
At this point I feel like maybe the card is defective somehow.
