Sound Cue Limit?

Hi there,

In my map there are currently 39 Fire01 sound cues, as I am using them for torches in an underground cave. These 39 sound cues work fine, however when I add a 40th one and any more after, the sound cue stop working. You can’t even listen to it play in the content browser.

Is there an actual limit to the amount of duplicate sound cues in a level, if so how would I increase this limit?

Or is this a bug in 4.9, and is there a fix for it?

All feedback is highly appreciated as always!

Thank you

I am having the same or similar problem in 4.8, after adding a larger number of sound emitters with the same sound cue, they all stop working. I can still play the particular cue from the content browser however. I seem to hit a “roof” of how many cues can be added, even tho they should not play if ther are not in range of the player. This happens both in the editor and in the packaged game client.

edit: A temporary workaround could be to duplicate the sound cue and change half of the emitters to use the new cue.

There is a global MaxChannelCount setting per project that defines the total number of SoundCues that can be concurrent in a project; this is set in the Engine - Audio section of the Project Settings editor screen. Also, SoundCues use a Sound Concurrency of 16 by default; this is accessed in the main Output node of the SoundCue. You can set this number to any you like; also, there are rules that can be applied when the limit of sounds is reached, such as Prevent New, Stop Oldest, Stop Furthest, etc.

One thing you’ll need to do is create multiple SoundCues to spread out the concurrencies a bit. So, instead of 39 Fire01 cues, create 10 Fire01_a SoundCues, 10 Fire01_b soundcues, etc.

The latter- 32 SoundWaves would be the limit for a MaxChannelCount of 32.

I know this is a bit old, but: “There is a global MaxChannelCount setting per project that defines the total number of SoundCues that can be concurrent in a project”
I saw in another thread that it’s actually max number of wave files, not sound cues. So e.g. one sound cue with 32 different layers would reach the limit when played. Which one is it then please?

That was fast, thanks Zak :slight_smile:
