No sound in VR game for a customer

Digging up this issue as well. Customers QA claim to have issues related to audio not playing after lanuching the packaged project (VIVE only, Windows 10). I had experience with this kind of issue however I always clicked anywhere in the screen with a mouse to make the window active and been doing VR and Unreal on a range of PCs and laptops. Customer is claiming that this might be Unreal specific bug since other titles developed with Unreal seem to have it common. The titles being Brookhaven Experiment, Amazon Odyssey.

Sadly I’m not able to repor the issue since it is working fine on either the headphones plugged through jack and in-built monitor speakers. The project itself doesn’t use any kind of audio systems running in the background. I assume it might be the case with Windows itself and how Unreal apps are handeled, what I mean here is that sometimes the app upon launch is started in the backround (running as non active window). As I mentioned earlier simply clicking on the window seemed to solve it and audio was always running after that. Dunno whether it might be the case here but build is distributed over on Viveport, hasn’t been published on Steam yet.

Tagging [USER=“14973”]Chance Ivey[/USER] here, as you might have any kind of knowledge related to the issue. (yeah I tagged you over on Discord as well ;P)

So I am the customer referred to here. After months of hunting for the solution to this I have FINALLY hit upon the answer today and wanted to share…

It really is simple in the end. Today I hit upon a comment in a thread about the 202 compositor error. This turned out to be the answer.
“If you move the position of your “monitor” (HMD) in relation to the others it is less likely to happen (i.e. compositor issues) from other windows opening on it.”

Within display settings you have to drag the second display (ie in this case the HMD) from its default position on the right of display 1 to the left instead:As the post I read correctly suggested, after making the change, Unreal opened on display 1 and didn’t interfere with the Compositor on display 2! It literally seems that Unreal is set to default to whatever display in on the right?!

Finally have sound in Unabomber, Amazon Odyssey, Brookhaven etc.
