Hi!,

**We’re wondering if (besides the FMOD license) we need to request any special Dolby or SRS license or display any logo or trademark for our commercial PS4 game.**

More info:

- We’d like to avoid any third party licensing issues other than FMOD.

- I’m manually setting the software format to FMOD\_SPEAKERMODE\_7POINT1  
to avoid the SRS 5.1 Surround Sound Encoder being used automatically  
(which is the only thing I’ve seen in the documentation that needs  
licensing).

- I’m initializing FMOD **without** FMOD\_INIT\_PREFER\_DOLBY\_DOWNMIX

**- Can I safely assume that forcing the speaker mode to FMOD\_SPEAKERMODE\_7POINT1 like that, any other speaker configurations the final user may have will be downmixed accordingly ?, what would be the impact of this?**

Thanks in advance!
