Hi everyone,

I’m facing an issue where I can’t have sound on consoles.

I’m having this error :

- Maximum XMA DSP codec pool size is 256 (for X1)
- Maximum AT9 DSP codec pool size is 256 (for PS4)

Does that sound familiar to you guys ?

Best regards,

Alex

The UE4 integration will set the codec pool size to the same value as the `RealChannelCount` as each real channel will require a codec. Because of this, RealChannelCount on Xbox One and PS4 cannot exceed 256.
