After upgrading Twinmotion to the latest version 2022.2 Preview 1, a weird problem came up. When opening the application, as soon as the main screen appears with the basic ground surface, my speakers start buzzing with a static noise which is independent from my volume settings. Even if I mute the windows volume the sound is there with no difference in strength. Even weirder is the fact that the sound changes according the window size, or depending on the window being full screen or windowed, or even depending the view angle of the 3d model. Furthermore it changes if the path tracing is on or off. Yesterday before the upgrade the program was operating normally.
I should add to the above said, that if any other window inside twinmotion is opened (like the open - save file dialog) the noise stops.
Is there any idea about what may be causing the issue, or better what may be the solution?
Thank you for posting about your issue and it does seem very strange behavior. You can try to go in the Twinmotion settings and turn off the "All sounds" to see if that helped. If that did not make a difference go back to that same menu and change the footstep setting to another sound to see if it makes a difference.
There could be something else causing this problem and maybe looking at your drivers windows update to make sure they are up to date. If the problem persists please contact us directly by following this link: https://twinmotionhelp.epicgames.com/s/case-community-page
I tried all the above with no effect. It seems to be relevant with the workload of the gpu. The speakers are inside my monitor, so I thought it could help to try connecting the audio output with a separate set of external speakers. In this case the static is not present. Probably something is making interference when audio and display is on the same box.
Before that I tried enabling V-sync and seemed to help a great deal but not completely.
I hope this helps if anybody else having the same issue.
I'm here because I have the same exact issue through my external speakers. It's faint, and if I have music playing I really can't hear it. If there are no other sounds playing, I do hear it. It changes pitch as I move around the model, and ceases when any dialog pops up.
I was having the same problem running Twinmotion education 2032.1. Drawing the power for the speakers using the usb connection to my motherboard was causing the static feedback. I used my wall/home power board to power the speakers instead of the usb on the motherboard. Still wired to the motherboard through the audio port on the motherboard. This seems to work. The sound did seem to get louder in accordance with how hard the GPU (Geforce RTX 3080) was working but also my speakers are super old and super cheap so it could be them.
I am a year too late but maybe I can still give an answer for whoever is interested:
I had the same problem yesterday and found out that it does not have anything to do with the speakers but actually with the GPU. The strange noise is called coil whine and it happens when your graphics card draws a lot of power which basically results in components starting to vibrate. That also explains why it stops whenever you open another window. I have read that this is quite common among high end GPUs (personally I own a RTX 4070 Ti).
The solution that helped me was limiting the FPS for Twinmotion in the Nvidia Contol Panel in the 3d settings (guess there is also a way for AMD users). I do not know if I made a mistake before that but it seemed like Twinmotion would pull as much FPS as the GPU was able to produce which resulted in crazy high temps and that annoying sound even in the lowest settings. I personally limited it to 30 FPS and now everything is quite and cool.
Exactly the same behavior. But for me it only happened when using the speakers of the monitor. Now I use external speakers (old set from creative with a woofer) and the problem stopped. Probably the amplifier of the speakers cut off the noise. But is CPU or GPU related because it changes the pitch according the movement of the model.
