I'm experiencing very bad sound stutters & puses when flying in FSX & other sims like FC2 etc. They last for 1-3 sec & are very severe when landing & you hear the RA call-outs 30, 20, 10....makes smooth landings impossible, but they also are present at altitude. They are worst when flying an heavy addon like PMDG NGX w Fs2crew & Coolsky DC-9. The thing is when I press Q & mute the sound the stutters are gone &  everything is smooth.

It started 3 weeks ago since then I have done:

-an complete computer system reinstall with fresh FSX install.

-updated all drivers, added newest Realtek HD Audio driver from their's site.

-tried different Nvida drivers & all kinds of pc system & sound setups, like sound through speakers vs headset, downgrading sound quality, checked HD for errors, turning off/on services in msconfig  etc.

-deleted fx_skidmark.fx from effects

-called Asus support several times & searched the net for solutions.

None of the above has helped I'm out of ideas?

 

Any help highly appreciated:) 

 

My system: Asus G73JW-TY190V - i5 460M (Gaming laptop)/ 4GB / 500GB / 17" TFT / Nvida GF GTX 460M /Win7 H.

Sound: Built in Stereo speakers , Microphone, Subwoofer, Realtek HD Audio.

1. Reduce sound quality to 16 bit CD quality or similar

 

2. Lower FSX priority or affinity

In the FSX sound menu (Settings > Sound), does it say "Default Primary Device" or the name of your sound card (eg. Realtek audio, or with me it says "Asus Xonar DX")? You need to make sure you have the Realtek sound card selected instead of the default primary one. Also, with the Nvidia GTX 400 series cards and up, they have onboard sound built into the video card. This was causing sound stuttering in other games I had played at the time.

 

If you go into the Device Manager, and go down to System Devices, and select the one which says "High Definition Audio Controller" (RealTek Sound is listed under "Sound, video and game controllers" if I recall when I had mine installed, so it shouldn't affect it). Right click on the High Definition Audio Device under System Devices and click disable. There may be more than one of them, so disable them all.

 

That seemed to fix my sound stutters.

I was having bad audio/video cutouts not too long ago. Traced it to a DPC Latency issue stemming from my wireless network adaptor, updated driver fixed the problem.. Hope this helps.

Thanx for the suggestions guys!

As it turned out it was mine HD, the HD check programs could not detect this specific failure as I found out on Asus forums. I've replaced it with an Kingston SSD & the stutters & puses are gone :rolleyes:

I guess my former HD, with all the moving parts inside just gave up...like an engine..anyway I'm very happy with my new SSD, it makes my w7, bootup, files transfering, games loading much faster, the performance in FSX is the same though.
