Speaker settings surround sound

Hi everyone,
I was searching for an answer regarding surround sound speaker setup. After much research unfortunately I couldn’t find any, so here my question:

I’m using the internal sound card (Realtek on Asus board) but I can’t get the rear and center loudspeakers to work in UE4.
Using the VLC player with a 5.1 wav file all loudspeakers are playing correctly. But after importing the dedicated mono files *_fl, *_fr, *.fc…etc (sound is imported correctly as 5.1 file) I can only hear left and right loudspeakers. Same is true for mono files from actors in the scene…
Am I missing something? Do I need to initialize the loudspeaker setting in UE4? Or do I have a driver problem with Realtek? Or anything else?

Any answer or hint even is appreciated.
Thanks

Hi Gero,

We aren’t immediately aware of known issues with this. We will do some testing to investigate.

Can you also attach your Dxdiag?

Thanks

Hi Stephen,

thanks for your fast response.
I attached the dxdiag file. Maybe you see something interesting I could not.

Question: should UE4 be able to use the default windows setup without hassle?

Hi Gero,

Would you be willing to share your audio assets? I’d like to use consistent conditions to test between us.

Thanks

Hi Stephen,
yes, of course I can send you a sample of my file.
How? (It’s too big to upload)
Thanks in advance

If you haven’t tried already, place your files in a Zip file, and attach that.

If it is still too large, let me know, and we will come up with another option.

Thanks

Hi Stephen,
Unfortunately, zipped the file has about 7MB, so it’s still too big to upload.
Another option would be welcome.
Thanks

Hi Gero,

My apologies for the delay. I am going to send you an email in a few moments with some information. Please be on the lookout for it.

Thanks

An update that I have successfully imported the files. Thanks! Now I just need to get my hands on a surround-sound setup to continue the test.

Hi Stephen,
Great! Enjoy listening in surround. I hope you can get it to work.

Hi Gero,

Due to the nature of the audio file, and the 7.1 surround sound headset we’re using for testing, I have had a bit of difficulty discerning which channels may or may not be playing. I did speak with one of our audio engineers though, and he let me know that there was a known surround sound issue which caused some channels to not play, and has already been addressed for the final 4.4 release.

The 4.4 release should be occurring soon, I suggest for you to test your issue again when it is released, and let us know if the problem is or is not resolved. If not, I’ll pick up the investigation.

On the plus side, while I was investigating your issue yesterday, I stumbled upon a crash which we are currently working to address for the release.

Cheers
