Samples sometimes don't play.

[JaJitsu]

Recently I've been having problems loading samples. I am loading the file as a sound effect to trigger in an event, it will actually work, but sometimes will just not play.

I've tried looking around at other threads but nobody seems to have the inconstancy that i'm having. The sound does play sometimes so I know it's working, but for some reason it will not play other times. Again it's inconsistent, so I don't even have a pattern of when it works and when it doesn't.

I've also tried having a counter that will add one every time the sound should play. Just to make sure I put the "play sound" and "add to counter" in the same event.
The counter would add one every single time so the event was working fine, but the sfx would still not play some of the time.

Does anyone have any idea what is happening here?

Hmm. It seems like the other samples are effecting it.
One is example is trying to open a locked door. Pressing down has the character speak. Standing still always plays the speech sound but if I press down while running the footstep sound effect causes the speech to not play.

I might be having more luck with channels but i'm currently using channels for background music.

Advice?
