Hello,

I am struggling to get the FMOD Studio profiler to playback in API mode. It works fine if API mode is turned off but if I click the API button and then press play I always get silence.

The way I understand it should play back from the API capture. I can see all this information in the API capture but the events just don’t seem to play.

Does it work for anyone else? Any ideas what I am doing wrong?

Thanks

API capture playback depends on the built banks for the Desktop platform being available in your project’s build subdirectory. Have you tried rebuilding your banks for all platforms?

I finally worked out what I had to do.

If anyone else gets this issue in the future try manually dragging the timeline off zero before pressing play. I only needed to move it forward by a tiny amount (50ms) and it started working.

I have this issue, too. I press play and no sound plays. I have to click anywhere in the timeline with the mouse, then the sound starts. Seems like a bug to me.

Also, when profiling, it would be nice seeing all the action in the FMOD Studio editor. Seeing the playhead / cursor move and see the position, see how parameters are changed and the automation they drag with them. It would help seeing what’s going on a lot better than looking at graphs.
