Game hangs up for a sec when using programmer sound.

Unreal Engine
1

So I’m trying to use fmod for handling the voiceover. But as soon as I set the programmer instrument name and play the game hangs up for a sec and I get this error message.

Anyone got a clue?

Hi Zsombor,

Can you provide the code or blueprints for how you’re setting this up? It’s hard to tell from this callstack alone.

Thanks,
Richard

Hi Richards,

Of course here you go.

Hi Zsombor,

Your blueprint looks fine. Could you confirm which version of FMOD Studio you’re using? There was a fix in 1.10.05 for programmer sound creation flags which would improve performance. Could you also try recording a Profiler session to see if there’s any RAM/CPU issues being recorded?

Its UE4 4.20 with 1.10.08. I don’t think its that its related to RAM/CPU since I’m getting this ERROR only on the first play. If I restart the level its all good.

Moreover, the game we’re working on is crashing on level restart and unfortunately we’re getting this error.

Have you ever encountered this error message in unreal?

Hi Z,

We can’t really understand much from these callstacks. Could you zip up your Unreal project and upload it? Go into your profile page, click on the Upload tab and upload your project there. It should ping support once it’s done.

Hi Richard!

Not sure if that’s a viable option since the game is pretty hefty in size 40+gb. Any idea about the restart crash? The log snippet is the very end of the crashlog.

Hi Z,

The callstack only says it’s crashing at the “setListenerPosition” function. My only thoughts are that an invalid value is being passed into it once the level resets but this shouldn’t cause a crash.

If you zip up the project only containing the Config, Content, Plugins, and Source folder, does this help reduce the size by much?

Hey Richard,

Thanks for helping out. Turns out it wasn’t fmod that was causing the crash after all. And the programmer sound bug was solved by modifying the sourcecode of fmod by our programmer.

Thanks for the update Z.
