Hi all,

Just wondering... If I play the same sound file (from a wav, loaded in with LoadSound) rapidly, in quick succession, it sounds just fine. But if I try and play various sounds in rapid succession (but not so rapid that more than 5 are playing at any one time) I get quite a bit of audio distortion and "clicks" on-device.

Assuming that the rapid-play of overlapping sounds is a necessity to what I'm doing, is there a way to better manage my sound instances to minimize or avoid this anomaly altogether?

I've not tried it myself but it could be the device mixer not handling short sounds very well. If this is on Android then try making all your sound files at least 200ms in length, even if some of it is silence, and see if it makes any difference.

Interesting. I hadn't actually considered it might be device specific. I'll give this a shot and see how it goes! Thank you!

Alrighty, so I finally found time to test this out and I thought I'd try one last thing... Switching back to MP3 music, rather than using OGG.

Doing so completely fixed the issue with the WAV sounds for some reason...

Interesting, the OGG system uses the sound subsystem to play music, it decodes the OGG into WAV in chunks plays it like a sound, so it will be mixed with the sound effects. Whereas MP3 uses the device hardware decoder so it should put less pressure on the system. M4A should have the same effect as MP3 as it also uses the hardware decoder, but has less license issues, so I'd recommend M4A instead.

No I used MP3 files for my music in the game rather than OGG files (and their relevant commands) and the issue with PlaySound fixed itself.
