Sound crackling distortion

[Bozdog 63]

Hi does anybody get this at all just occasionally   sound gets distorted for a second or two this can be the ambient sounds or the air traffic control voice only happens for about a second seems to have a slight pause the same time and flying on the VR headset it actually seems to crash the VR and I have to reload the headset does also occur in 2-D as well though. On Windows 11 just wondering if it’s an MSFS or /driver issue or a hardware issue no sound issues reported if I run  any performance checks on Windows 11 and all drivers up-to-date. 
 

New PC so I’m always a bit paranoid that the hard ware is faulty 

It’s very intermittent

thanks all

I recently upgraded to Windows 11 and noticed this too. It didn't happen with Windows 10. It could be driver issues

I'm on Windows 10 and noticing the same at about every flight after SU8 (with no VR, haven't tested with VR). I thought I had my doors open.

I get the same since upgrading to win 11, to be honest I'm relieved that others are also experiencing this weird phenomenon, i thought it was my PC. I get it occurring on YouTube as well.

It's a Windows 11 issue. I've rolled back to Windows 10 for the foreseeable future.

It might be a ground loop issue that occurs when your gpu is under load. I've had it and it has gotten progressively worse to the point of it being unbearable.

Strangely enough, mine has got better over time, to the point where I hardly notice it at all and only on very rare occasions. I have however been delving into the reg in order to get better performance in MSFS.

Was having this intermittently as well, and wanted to share a suggestion that ended up being a permanent fix (on my system at least).

What I realized is my speakers had a digital optical input, so I swapped out the analog and replaced with a toslink instead, then changed the audio output in Windows and the sim to the the digital - lo and behold no more crackles and pops, and the associated stutter was gone as well.

I'm guessing, but perhaps this has to do with the DAC on the sound device, particularly if the GPU is saturating the BUS (creating latency and noise); that's why a digital bitstream bypasses this issue.   

Hope this helps

I'm using Windows 10 and having the issue.

I tend to agree on this.

I had the same issue many moons ago running Windows 7 64 bit with FSX.  This was on a newly built PC.  It turned out that the Bios needed updating.  This is far beyond my pay grade and was done for me, but fixed the issues.  Just a thought for you guys.

I'm getting this with Win 10. I've got an optical speaker connection but I'm not prepared to sacrifice my connection just for a little blip very occasionally. It gave me a fright the first couple of times but it's easy to ignore now.

Brilliant guys thank you very much for your comments although  I guess it’s not brilliant for you as well  but I am relieved  I am  not the only one having the problems. 
 

I just get a bit paranoid whenever I buy something new that if there’s a 1 in a million chance of a faulty part I always seem to be that 1!  If only it was the same with the lottery🤣😂🤣

I’ve just re-installed  the latest sound driver for my motherboard so fingers crossed it might improve if not I’ll just try and make myself put up with it!  I am a bit ocd about getting everything to work perfectly😬

Thanks again  👍

Let me guess - you’ve got an on-board Realtek sound device?

I used to have this problem, but after disabling the Realtek sound device and switching to the sound device on my 3090 no more problems 🙂

Yes that’s the one.  My speakers not compatible with a graphics card.  They are about 20: years old before HDMI. DP even invented got an old sound blaster in loft maybey should  fit  that and my old 33k modem    😎
