This developed post update to 24H2 and I'm perplexed as this wasn't happening pre.  Since 24H2 update a few days ago I have tried installing the latest AMD chipset drivers as well as RealTek's very new drivers that may be related to this 24H2 update.  I thought the chipset driver update may have fixed it but alas on my last flight it's back.  I also did a clean reinstall of the latest NV driver for my GPU.  I had something similar 3 or 4 months ago and disabling all other sound devices helped but not this time so I'm perplexed.  Doesn't happen in other games.

If you can relate to this and found a cause/cure jump in.

This is a duplicate request for insights in the hopes of finding someone using 2020 who has had this issue crop up.  I posted it 4 days ago in the Win 11 subforum and despite 110 views no replies as yet.

Thanks

I don't have any solutions but you could possibly look into running LatencyMon while you fly and experience these cutouts. Perhaps it's due to high DPC latency which is an age old issue that is known to cause audio problems, might narrow it down to a specific driver or function. 

Might want to add your question in the Windows forum.

For example in this area:

do you still hear the UI sounds?

No solutions, except for reinstalling the SSD (Win10) I had cloned before recently installing that version of Win11. Win11 has been terrible with 2020, doing exactly that: audio and graphic stutters which at times is unacceptable to fly with. After 5 days of searching and trying some things, 40 minutes ago I reconnected the Win10 SSD. I'm flying smooth as silk again.

Also I saw a thread on the microsoft flight sim forums from early October discussing this problem. No one had a fix it seems, blaming it on Windows 11 and waiting for something from MS...

15 minutes later, just finished the flight and it was perfect. I'll stash that Win11 SSD away until someone figures this out.   

I did three things and so far in this flight no audio hitches but i'm only halfway to arrival so we're cautiously optimistic.  Instead of what I've always used, Windows Default, as the sound device for both streams, I used the one assigned to the specific output, in this case my studio monitor headphones.  The next thing I did was remove a RealTek Audio Console or Controller or whatever it was called.  And finally, just reinstalled the latest Realtek driver from my mobo's website, which I had previously installed.  If this doesn't end up resolved I did DL LatencyMon and can start there next.  Anyway 🤞  

Well, off we go to see if LatencyMon can help pinpoint the issue as they're back again in today's flight though not super frequent.

Sorry Brocky, yes I hear everything that should be there.

Well, cautiously optimistic again.  LatencyMon didn't show anything meaningful other than clearly I should not be having cutouts from DPC latency as am roughly 10x lower than what is suggested as required to have no cutouts.

What I did do was move my 2nd screen over to the motherboard's graphics chip instead of out of the 4090.  I did the exact same flight done earlier w/ cutouts, probably 25x during a 90 min flight, down to zero cutouts.  One test flight doth not confirm the fix but does look hopeful!

Appreciate you reporting your results Noel. I did reinstall the Win11 drive and updated the Realtek drivers, disabled any other sound devices that were listed; no joy.

Back in WIn10 land I just flew flawlessly for 2 hours.

I can easily swap the C drives back and forth if there's something new to try, but I don't think I have any other graphic ports available for monitor number 2.

Anyway, good luck! 

 

Well, thought we were good but again today same thing is happening.  I had been getting very  rare cutouts since the last post but today, lots n lots, pretty much constant.  Latency Mon during the current flight says everything ought to be fine.  I wonder now if 24H2 was a red herring and that perhaps it's a hardware related issue, bad cable, bad port, something like that.  I will try moving my 2nd display to the mainboard's GPU and see if that helps, wiggle various cables etc.   

 

Hmmm. 

I started to notice the same thing in recent flights Noel but it is only happening on the ground and predominantly while GSX is active in drone view.  Not saying it is a GSX issue but i have noticed from time to time sounds will cut out while I am in drone view before or after the flight.  No issues in flight however I've definitely noticed the sounds cuts.  Are your happening consistently throughout the flight and losing all sound altogether? 

I am on Win10 but similarly just had the 2H24 update and Intel chipset with a 4090.  Nothing to your extent of them happening constantly though.  

I wish I could offer help but I don't think you are alone... 

Those experiencing audio cutouts is there a lot of traffic present, and does it happen mostly at large airports?

I have experienced audio cutouts mostly at Flightbeam Denver-KDEN, and if I reduce traffic (PSXT/AIG/FSLTL) it eliminates the cutouts. In my case it seems to be related obviously to traffic, but I suspect it's objects in general. I'm going to try a test at KDEN with traffic with and without GSX to see if it's more of a general object issue.

I also suspect in my case the real cause is limited hardware resources, namely, memory speed, CPU horsepower, bus bandwidth etc. and that limiting traffic reduces workload that's overwhelming limited resources.

In my case yes and the other culprit I found were when the airports themselves had sounds.  For example, DD KEWR's terminal sounds were actually causing my PMDG cockpit sounds to cut out, especially the speed call outs... 

Disabling the sound files in the scenery resolved the issue.

If running GSX, shut down coualt in the task manager after pushback and see what happens.
