Speedbrake sound glitching

[Cjayster13]

When opening the speedbrake, the sound is stuttering and glitching. 

Thanks

Indeed, I hadn’t flown the F-4 in a few months so I wondered if it was a new addition…

But that sound is exactly the same regardless of airspeed, even on the ground

Yes me too!

Hey there. It appears that since some update our (still correct) sound is overlapped with some DCS default speedbrake sound that pops in/out at high frequency.

Not sure yet why, but this DCS default noise is the offender, creating the flapping sound. It wasnt there before and now its suddenly there. Probably gotta poke ED about it, cheers.

Thanks. I think Cobra already contacted them and provided internal details :)

For me it's still like pulsating sound of turbulent air.

My sound is glitching as well in the F4E. It doesn't seem to be related to the speed brake since it starts a soon as I load into the aircraft even with the engine off. I tried reinstalling but didn't make a difference.

That is because you have not received this build of the F-4E yet. It is fixed internally but not available to the public yet

Could you perhaps record it on a quick video or something? Potentially you are doing something wrong or it is correct behavior. Hard to guess based on that. For example, with wind even on a cold aircraft you will hear the engine blades making noise depending on which direction the aircraft is facing.

Here is a recording and a track file of the sound issue. I just a made a mission with a cold start and nothing else in it. I removed all mods, reinstalled the F4E

and repaired DCS. Flew the F4 about a week ago without issue so not sure exactly when it started. Same noises with engine on. Not occurring with any other modules so far.
