Hello! I’m using a transceiver effect to play 2 different layers of a track in different locations. I have the main event set up with 3 tracks (one playing at all times) and I have a pre-fader transceiver set up on 2 of the tracks on channel 0 and 1 which get received by 2 “child” events that are set in their own emitters at the desired locations. Works great in editor but I get no sound from the “child” events. Made a dev build and there are no errors directly pertaining to the issue in the log.

Using Unity 2022.3.43f1, FMOD Studio 2.02.21, FMOD for Unity 2.02.21. Any help appreciated!

Hi,

What version of FMOD are you using?

Would it be possible get record a profiler session ([FMOD Studio - Profiling](https://fmod.com/docs/2.02/studio/profiling.html)) while connected via Live Update ([FMOD Studio - Editing During Live Update](https://fmod.com/docs/2.02/studio/editing-during-live-update.html).

What we will be looking for if the child events are behaving as expected, e.g. playing and producing audio. I have a hunch that they may be stopped by the `Stop Outside of Max Distance` ([Unity Integration - Settings - Stop Events Outside Max Distance](https://fmod.com/docs/2.02/unity/settings.html#stop-events-outside-max-distance)) behavior if they are spatialzied.

Would it be possible to set the following FMOD Integration settings:

and share the full player logs:

Sorry for the late reply on this! As stated, we’re using Using Unity 2022.3.43f1, FMOD Studio 2.02.21, FMOD for Unity 2.02.21. Attached is a profiler session and the player log. I entered the affected area at 50 seconds. Stop Events Outside Max Distance is NOT enabled.

Thank you for sharing the information, and sorry for the late response.

Unfortunately, with the info provided, I have been unable to reproduce the issue on my end using a similar setup.

Would it be possible to upload your project (or a stripped down version that still demonstrates the issue) to your [FMOD user profile](https://www.fmod.com/profile#uploads), so I can take a closer look at what might be going wrong?

Additionally, could you please try using [Studio::EventDescription::loadSampleData](https://fmod.com/docs/2.02/api/studio-api-eventdescription.html#studio_eventdescription_loadsampledata) to see if preloading the events resolve the issue?
