Sound randomly Changes

[Cael]

Since i i started using my new MSI (TwinFrozr Series) GTX 760 OC , my sound fluxuates up and down randomly sometimes its so lil people in my house think its just me then theres times watching a twitch cast it almost goes total muted. I never had this w/ my XFX Radeon HD5750 (Yes i use HDMI Out for my audio)

i know the issue is HDMI Audio related as this doesn't occur when i use my Onboard Realtek Sound or USB Headphone DAC

i have disabled loudness Correction, yes i do have skype i have disabled Auto Volume control on Communications, but i don't know how to stop Skype for windows' Auto gain control.

what can i do to stop this? and is this common with HDMI Audio on Nvidia cards? at first i thought it was the Differences in TV's i tend to swap from every few months, (after while i move back to my rom and for a few weeks every handful of months i use the livinroom 47'HDTV) but wasnt till i noticed it never happened to onboard sound i knew it wasn't something w/ the big screen hdtv, (i know it has its own AGC but this occurs w/ my 22' HDTV which has no AGC)

As this is apparently a new Video card, that apparently has never worked correctly, I would be looking at the video card (and possibly as defective) rather than anything else.

Reseat the card - with the PC powered off, remove the card then reinstall making sure its fully and correctly seated.

If reseat doesn't help, I would suspect the video card.
