June 22, 201213 yr I recently upgraded my video card from the 460 to a 670 and everything is running pretty awesome, for the exception of the sound. I connect my monitor to the video card via HDMI, and I realized that the sound was crackling and having static problems. I found that this was due to the video card driver installing an actual Nvidia sound driver that was conflicting with the onboard sound. I disabled the HDMI sound via the nvidia control panel and device manager, and then reinstalled the latest version of the PZ68-V chipset audio driver and it was ok for a while. I did a flight from KMSY to KDAL and noticed toward the latter part of the flight that I still noticed the crackling in the sound. However, when I alt-tab out and play some music on itunes, it sounds fine. Does anybody know what the problem might be? My cpu is overclocked to 4.4 ghz at 1.29v, running fsx at high 50's and low 60's, I also have the video card clocked to +95 mhz for a total of 1180 mhz, and +300 memory offset via Precision X. The temps on the card don't go over high 40's or mid 50's while flying. I'm also running the 301.42 drivers. R. Dawson
June 22, 201213 yr The last time I had this happen I deleted the FSX.CFG file and let FSX build a new one and the sound problems went away...might be worth a try.

I did that as soon as I installed the new video card to get rid of any potential problems, but I'll try another flight, if the sound happens again, I'll try getting a new cfg in there. Was it the same problem that I'm having? R. Dawson

June 22, 201213 yr Author I think it I might've been because I did it when I had first installed the new video drivers, not when I installed the actual on board sound, that just might be the fix, thanks. R. Dawson
June 23, 201213 yr Author Update: No cigar on the new FSX.cfg, I did manage to finally get my video/inspector settings up to par and it's running butter smooth now, but the static feedback is still there. I poked around and saw that my microphone was sending feedback which is what was making the crackling noise. When it's disconnected, the feedback stops. I haven't tried a compete flight yet to see if that completely stops the crackle/static. Does anybody have an idea of why my microphone would be sending feedback through my speakers? It was working fine with the 460. R. Dawson
June 23, 201213 yr Call nvidia if you have some issues with the GTX 670. I did and they sent me a new firmware that I updated it with. It seems to have solved some issues (So far I don't know if I have the sound problem or not since I just have headphone. Manny Manny Beta tester for SIMStarter
