No sound when launching on Android device

Hi, I develop one demo in UE4.10.1. And play it in PC, it has game sound(i put one soundcue in the scene).
However, when i lanuch the game in Android device try to play the game, i found that all the other game elements are working same as on PC, except there is no sound(a mute game).

Anyone knows why this thing is happening?

Hi ZORRO.JB,

  • What steps are you taking to package your project?
  • Have you checked to ensure that your SDK is up to date?
  • What device are you packaging to?

Hi ZORRO.JB,

We have not heard from you in several days. I am marking this as answered for tracking purposes. If you are still experiencing this error, please comment with the requested information.

Hi I seem to have the same issue deploying on OnePlus One. All sounds work just fine within editor, but I can’t hear any sound while the project is launched on the phone. I’m using the UE 4.11 and AndroidWorks from the installer coming with UE. I simply click the Launch button and select my device to launch to. I’m using the blueprint “Play Sound 2D” nodes and the UMG feture of button press sound. Any ideas what can be wrong?

Hi Kaspi,

  • What device are you attempting to deploy to?
  • Does the sound work in a project packaged directly to windows or is this error limited to the device?
  • Have you checked to ensure your SDK is up to date?
  • What steps are you taking during packaging?

i’m running into this as well. sounds on an S4 are fine, but testing on a Note 4, certain sounds are missing. i thought it might be the sound sample rate on newer devices, but one sound at a low rate does play fine, even though others at a low rate don’t play. all other sounds at a higher rate also play fine. low rates are important though, as it saves a considerable amount of packaging size. will update more info as i test more…

[edit] ok, tested different sample rates. 16khz and up seems ok. anything lower than 16khz on a newer device cause the sound sample to drop out (older devices were ok though). ‘retro’ sounds don’t really need anything more than that, so kinda wondering why 8khz wasn’t working.

  • Do you have any specific sound files that aren’t working or is it any sound lower than 16khz?
  • Does this occur in a clean, blank project with no additional content or is it limited to one project?
  • What steps can I take to reproduce this on my end?

Solved! You should package all resources under content once, after that when you launch the game on andriod device, sounds will come back to your game~~
