iOS OpenAL memory leak when playing Sound many times

EricCarr

Memory testing my platformer and noticed every time two sounds (.wav) play together (or even the same sound over and over in a short period of time), it a creates memory leak when monitoring in the Instruments app.

OALSource:AddPlaybackMessage

This was happening on an older player (2017.11?) so I updated to the latest (2018.6.3) and the issue still is there. I'm guessing it's been there since the switch to openAL.

This url suggests a possible fix:

Other details: In my platformer (similar to mario), there are tons of sounds playing, so it adds up quickly.

Usually after a few hours of testing, after leaving the app and returning to it, sometimes no sounds will play and I have to kill the app to get sounds working (mp3 playing in the background works fine).

I cache all sounds into a global variable and issue : play() on them as needed.

Thanks,
Eric

you should also add it on github as an issue.

Yeah, nice catch @EricCarr, add it to Github! Do you have a minimal example of the bug? Does it only happen on iOS?
