P3D V4 Sound Stuttering on Long Haul Flights

Recommended Posts

I have been working on a new build and testing now that I have returned from Afghanistan and can get caught up.  I recently tried a series of test flights and I am not too sure if I might have a problem.  So short duration flights of under 5 hours with the PMDG 737 and associated FS2Crew program, has no issues.  However, long-haul flights appear to have major issues. 

First I have not tried either the B777 or 747 with FS2Crew on say cross-country flights, but I will give that a try to see if there is any difference.  What I have noticed on the long haul flights was FPS instability going from the mid 40's at the start to single digits.  I found the culprit being simlink form Navigaph and that problem no longer remains.  Instead now there appears to be severe audio stuttering with loss of audio via the FS2Crew application, however, the application still works you just don't hear anything.  The audio stuttering has no effect on FPS.  Whether or not I mute the audio, the aircraft still flies and functions normally with FPS in the mid 30's to mid 40's.  Both flights were able to be finished but with no audio.  I also tried to reset the audio via the FS2Crew Control Panel, but no avail.

Test Flight 1: PMDG 747 with FS2Crew from Flightbeam KSFO to Aerosoft EDDF

Test Flight 2: PMDG 777 with FS2Crew from Flightbeam KIAD to Fly Tampa OMDB.

That's a tough one.

Are you using "default" settings for all your audio hardware?  You're not changing the bit rate or anything, etc for your sound card.

Originally I had all default settings.  I did see a post on a forum to change from 16bit 48000hz DVD quality to 44100hz CD quality, but I have not tested it yet.  I have a Logitech G933 but I went and uninstalled the software just as a precaution.  Was going to try and redo a long haul flight tonight, to see if that does anything.  Also, side not sure if it matters but I did see in a couple of places not to use 7.1 within headphones.  I have DOLBY access and Windows Sonic which I use for movies and other games, not P3D.  I generally deactivate it, could that matter?

It could possibly matter.  There are 1000s of different possible hardware / driver/ user settings out there.  You may have to experiment a bit.

By Sonic you mean Sonic Studio?

OK so update, I was able to complete a cross-country flight today form KDEN to KIAD with the PMDG 777 with no visible issues.  However, after I landed and was unloading the sim didn't have a visible error, it just CTD with no error warning in any logs, that seems odd, might be some of my OC settings, but I would think while in flight with all kinds of calculations being conducted it would happen then and not on the ground.  I am going to keep the same settings and tomorrow conduct a flight during the day, but set the sim to dusk-night-dawn setting and do a flight from KIAD to either EGLL or EDDF and see what happens.  I did see that I had Windows FB enabled, so I turned that off, I turned the audio settings to 16bit 44100hz CD quality, plus my Logitech software had surround sound enabled.  I think that one of these three was the culprit.  I would say that if it was the SS, then that is sad, as the sim sounded a little more realistic with SS engaged.  I will let you know the results.

Finally was able to conduct a long-haul flight with absolutely no issues.  While I am unable to put my finger on the exact issue, I can say with high confidence it would have been one of the following area's; 

1. Incompatibility with Logitech G933 Software

2. Incompatibility with either headphone's set to surround sound settings and/or audio settings set to 16bit 48000hz DVD Quality vs. 16bit 44100hz CD quality

3. Finally, either P3D or PMDG or FS2Crew incompatibility with Core I7-8700k with Hyper-Threading enabled.

I think that the problem and/or bug is within one of these areas or possibly within multiple areas.  While I am not a computer programmer, I just found a difference here with having tried multiple flights from multiple locations with multiple aircraft and settings.  Of course, I could be way wrong.  I just thought you might like to know what I tried and did, and their result. Please feel free if you have any questions.

Thanks for your support and help through this process..
