Hey! Im getting this error while trying to build for PS5. It says that it’s missing the libatrac9.dll plugin. I seem to be missing the PlayStation SDK (the “SCE” folder inside of my “program files” folder is missing) that I need. I tried reinstalling FMOD Studio 64 bit to see if somehow it got missed in the install but nothing appeared. Where can I find that plugin in order to copy it next to the FMOD Studio executable? ---

The PlayStation SDK can be downloaded from the Sony developer wesbite. ---

Thanks for responding so quickly! I’m on the dev website but I don’t see a place to download anything for PlayStation specifically. ---

Ok, well someone on your project must have access to the PlayStation SDK so I suggest you contact them for assistance. ---

Hey Andrew! Sorry about the massive gap there but we ended up pivoting away from console builds at that time so my problem was no longer a problem. We’re now back to releasing on consoles though and I have a continuation of this issue. I’ve secured the SDKs from Sony for PS4 and PS5 but they dont include the .dll file that FMOD says I need. Instead there are alot of .prx files and .a files which, from my understanding, the .prx files should work very similarly to a .dll. All in all I need a little help figuring out which files I need to put where. ---

The relevant docs are here : [https://www.fmod.com/docs/2.03/studio/getting-events-into-your-game.html#compression-and-encoding-settings](https://www.fmod.com/docs/2.03/studio/getting-events-into-your-game.html#compression-and-encoding-settings) The specific section is here : ![image](https://canada1.discourse-cdn.com/flex036/uploads/fmod/original/2X/c/c714d46928a6dde5323a550684a3d570ade89ac5.png) Make sure you get the “External Tools” package as specified here ^^^. When you’ve installed an SDK that includes that package, you’ll find the relevant file in this folder : C:\Program Files (x86)\SCE\Common\External Tools\ATRAC9 Windows Library\at9
