UE4.25 Audio Engine Bugs - Update from 4.22 - need help!

Hi Dan,

No. I think 32 is enough, and I find if set it to 128 may cause lag too on iOS. So I did some work to prevent it happens.

I find when I update to 4.25 **some but not all of **sound cue have a checked setting-override concurrency under Voice Mananement, I didn’t check this myself in 4.22. I didn’t know why they are turn on.

After many times of test on both iPhone and iPad, I did some change on iOS settings like this:

This changes worked, the problem has some improvement but still not good enough. Any Suggestion?

Base on this settings, go on tried a lot:

  1. turn off all sound cue Attenuation
  2. Prime all short sound cue
  3. Retain all short sounds wave
  4. PreLoad sound cue
  5. Use Stream Caching (Experimental)

After all, it is a little better but still not good enough. And the fixed result is not stable, that’s annoy. Some times iPhone gets right but iPad wrong.

I had a long struggle with this settings but stll not find a perfect fix.

Why it is all right on the windows Editor but laggy on iOS. Any body konws?

I can tell it must be something wrong on iOS settings, something like: buffer, memory, cache or something background method wrong.

I hope it could be found out and fixed soon.
