Audio cut-out on new GTX970 until screen ration changed

[Alan Hudson]

Hello all,
I've been having a problem with my gigabyte g1 gaming gtx 970. Each time my computer has to change what I assume is the resolution on say a game launch or a serious graphical alteration. I can rectify this by cycling through my display's (LG 37LF75) ratios but this is as you can probably imagine, becoming quite tiresome. I'm relatively sure it isn't my display as this never happened with my old R9 270x and I'm pretty sure it isn't driver related as I was careful to clean the registry using display driver uninstaller prior to installing Geforce drivers. Anyone have any ideas on this or is my display just on its way out?

*edit*
Forgot to mention this doesn't happen on all games, just certain ones i.e. Shadow of Mordor.

Post your build

CPU- AMD FX6300
MOBO- MSI 970A-G43
V-Card- Gtx 970 G1 Gaming
RAM- 16gb Avexir 2400Mhz
Storage-64gb SSD
1TB HDD
PSU- CX750

I can confirm also that it is definitely caused by a resolution change as altering the launch resolution for a game ordains whether the sound is audible or I have to jump through ratios again.

Is your audio coming out of the 970 via HDMI?

That is correct yes

'Each time my computer has to change what I assume is the resolution on say a game launch or a serious graphical alteration.' - why would it do that?

Leave the resolution at the native resolution of your monitor.

(sorry for the belated response have built a new pc in the meantime and have been slowly re connecting various accounts)

I always leave it and all games at 1920x1080p but I should say more accurately my tv likes to change from 'just scan' mode to 16:9 mode which kills any audio for some reason 🙁 looks like I'm just gonna have to buy an actual monitor.

Yep. Sounds a finnicky TV. A monitor would be good.

I've figured it out! After mucking around in the Geforce control center, i found that physX audio is set to either GPU or CPU by application, by forcing it to CPU the problem no longer persists! I assume the pc doesn't like the switchover or something? Cheers for your time i7Baby ^_^ have a best answer.
