Hi, I have a problem with 2 random nodes combine mixer node.
It’s simple sound cue for footsteps.

As you see, simple footsteps with surfaces through mixer node.
I want these two sounds play on just same time, but there has very little delay.
It’s played one by one.(very little latency about 0.2ms though)
and when I clicked play cue button several times for play all sound waves in 2 random nodes, and then It works. Played just same time.

(I also tried prime on load at the sound cues, but dosen’t work.)
(It’s not only happened on sound cues, but also happen on editors)

It’s because I put on too many sound waves on random node?
If so, how many waves are enough for prevent this problem?
I can’t find same problem with me in this community.
So If you know how to fix it, Plese let me know.

Take a look at your waveforms in an external editor, like ‘audacity’, you’ll find that some of them have a small piece of silence at the start, probably.

Thanks for reply.
I checked all waveforms again and it isn’t.
and if so, it will happen always but after played all random nodes,
these two random nodes play on just same time.

Hmm, not sure. You could always zip them up ( the waves ) and attach here, and I’ll take a look.
