I have MSI ntel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz, turbo boosted to 3.4 GHz, Nvidia 1070, 16GB RAM .FSX SE 

When flying planes like PMDG 777/747v3, Aerosoft, etc. I get micro stutters when ATC callouts are playing and when callous/ touchdown sounds are playing as well as some button and switches sounds. Its all random and happens randomly throughout the flight. It was not like that in the beginning when I installed FSX and the payware add-ons. I guess something must have happened. I use Nicks Nvidia profile inspector settings with V sync Off. Unlimited frames set.

Please Help

 

Thank you

You did not indicate a sound card or whether you are using the on-board sound.  A dedicated sound card might help.  In any case, you should make sure the drivers are up-to-date.  I use Driver Booster to update drivers for my hardware but there are many driver update programs.  The on-board sound drivers are frequently updated.  Go into sound settings and make sure your card is recognized.  Sound is not perfect in FSX or FSX-SE but you should not be seeing micro-stutters.

Best regards,

I am using on board Realtek HD Audio driver and it is up to date.

I've noticed the same thing on my system.  From time to time, on an initial flight, when ATC initially plays, I've gotten micro-stutters as well.  It eventually goes away, as the flight progresses.

I also am using an on-board Realtek HD Audio driver and it also shows as being up to date.

I did notice that "Nvidia HD Audio" also appears under the Sounds tab in the Device Manager.  Could there possibly be some type of conflict? 

Also, perhaps it has nothing to do with the sound, but I've noticed micro-stutters when taking off and landing, when the aircraft is roughly around 200 Feet  or lower in altitude.  It's like the flightsim has to load something quickly, so freezes for a split-second, then continues normally. 

Exaclty the same thing. AND I have Exactly the same Nvdia HD Audio driver and Realtek HD Audio Driver on board. Did you fix the problem by any chance? I tried disabling the Nvidia audio driver but same thing happens. I dont think its the confilct. If you have VLC player installed, try deleteing it. 

I haven't made a flight in a while.  Will try it again to see if still an issue. 

I'm not sure what VLC player is, though.

Hi folks!  Long time, no post for me...

"Sounds playing causes brief lag" doesn't surprise me, especially nearing touchdown. A lot going on, loading sounds and animations not that are not already memory resident.

I remember long stutters whenever landing on a runway facing a big city skyline (e.g. KSEA RW 34*).  But with today's systems this may be greatly reduced or go unnoticed.
