Hi.  
We would like to ask you about changing FMOD\_CHANNEL ORDER from FMOD\_CHANNEL ORDER\_DEFAULT to FMOD\_CHANNELOR\_WAVEFORMAT because the speaker configuration we think is different.  
[https://www.fmod.com/docs/2.02/api/core-api-common.html#fmod\_channelorder](https://www.fmod.com/docs/2.02/api/core-api-common.html#fmod_channelorder)

1. I would like to ask you where I can modify FMOD\_CHANNELORDER.

2. If we proceed with the modification with FMOD\_CHANNELORDER\_WAVEFORMAT, we would like to ask you when we need to modify it.

Thank you.

You can change `FMOD_CHANNELORDER` when creating a sound with [`System::createSound`](https://fmod.com/docs/2.02/api/core-api-system.html#system_createsound), by setting the `channelorder` in the [`FMOD_CREATESOUNDEXINFO`](https://fmod.com/docs/2.02/api/core-api-system.html#fmod_createsoundexinfo) exinfo struct.

`FMOD_CHANNELORDER_WAVEFORMAT` is for internal use only and will not work with exinfo. If you want to match the speaker layout of `FMOD_CHANNELORDER_WAVEFORMAT` then you can use a [Channel Mix](https://fmod.com/docs/2.02/api/effects-reference.html?search=mixer%20dsp) dsp to assign each input channel to an output channel/speaker of your choosing.
