Sound is not playing when using launch on Shootergame sample

I am running on a fresh installed copy of UE4, and a fresh downloaded sample FPS project.
When I do simulate or play in editor, everything works fine.
But, when I “launch” game, there is no sound. windows mixer shows that volume is always at max, but I could hear nothing. I’ve done it twice and results are same.
Has anyone encountered same situation?
I am using Windows 7 64bit, and an Mbox 3 as audio interface.
I will provide more detailed system specs if need be.

Hey besthsq,

I wasn’t able to reproduce this issue on my system. Are you doing this via Launch button on Toolbar? Can you give us output log after doing your Launch game? Thanks!

Yes I did it via Launch button on toolbar. This time I did a full restart of my computer. It happened again. log is to big to paste here though. In what better way can I hand it to you?

You can copy log and paste it into a text file and attach, or simply grab log from your project’s Saved\Logs folder and attach that. Thanks!

You should double check in your Editor Settings under Play that no sound option hasn’t been accidentally checked.

log file is too big (~2.5M) for attachment.

no sound option was not accidentally checked.
Again like I said audio output appears to be always at max in mixer. Looks like some kind of audio glitch to me.

Hey besthsq,

Just wanted to check and make sure: are you still experiencing this issue? Does this happen with any other projects or is it just ShooterGame?

I’m sorry I am unable to provide further feedback, as haven’t been doing anything with UE4 recently. Did you find any clue why this happened?

Not so far, sorry. It might help to see if we can narrow cause down a bit. I’d like you to try and see if this happens in a new project as well as other projects from Marketplace. I would also be interested in a step-by-step guide you can follow in a new project that causes issue, if possible.

It would also be good to get your dxdiag, if you don’t mind.

I understand if you can’t get to it right now, but I’ll keep an eye on this thread for whenever you can. I appreciate your patience so far, and I want to get this resolved for you or at least entered in our bug database as quickly as we can.

Thanks!

Hey besthsq,

We haven’t heard from you in awhile, so I’m going to mark this thread as resolved. If you get a chance to look into what I suggested above, please feel free to update thread and mark it as unanswered and we can look into it further.

Best,

I was also having this issue, but managed to fix it. Apparently Sound Classes weren’t specified in Project Settings.

Make sure these are selected:

Project Settings:

  1. Default Sound Class is Master
  2. Default Base Sound Class is PSM_DuckEnvironment

Thank you for information. I will give it a try.
