I’m having issues connecting to Unity 2022.3.13f1 on Mac.
My colleague who is on Windows has no issues, and my other projects in 2.02.23 are working with various Unity versions.
The platform specific and Editor settings look fine, with live update is enabled and the sockets set to default on both ends. We tried specific settings for macOS just in case, but it’s still not working. I’ve also tried deleting the bank files and rebuilding them, also doesn’t help.
The connection error in FMOD says:
Studio was unable to connect to «localhost» as a connection error occurred: Connecting.
I’ve gotten this error twice, but it doesn’t happen every time:
```auto
[FMOD] FMOD_OS_Net_SetNoSignal : setsockopt SO_NOSIGPIPE failed 22
#0 GetStacktrace(int)
#1 DebugStringToFile(DebugStringToFileData const&)

#13 FMOD_Studio_CommandReplay_SetUserData
#14 FMOD_Thread_SetAttributes

#17 thread_start
```
We’ve tried everything we can think of now, so hope someone can help!

Hi,
There have been some fixed to Live Update since 2.03.07, would it be possible to update to [2.03.09](https://fmod.com/download#fmodstudio) and let me know if the issue continues?

Hi, thanks for the fast response!
I’ve updated to 2.03.09 now, but I still have the same issue. I even re-cloned the whole repo just in case, but the popup about the connection error appears.

Thank you for testing that!
I have intermittently been able to reproduce the issue but FMOD is still able to reestablish a connection. I will pass on my findings to our development team to investigate further. Thank you for bringing this to our attention.
Are you able to reproduce the issue in an new Unity project with a very simple FMOD set up?

I have the exact same issue and errors (both in FMOD and Unity). I’m on a Mac M1, Sequoia 15.6.1. I’ve downloaded the latest FMOD version 2.03.09 and updated to the same version in Unity for FMOD. It’s currently setup very simple with the standard “example.fspro” project in a new game project in Unity.

Thanks for the info.
We are still investigating the issue, I have added your interest and I will update the thread when I can.

Hi!
Sound designers and musicians are reporting issues with live update since updating across multiple projects…
- Unity 6000.0.56f1 + FMOD 2.03.07
- Unity 6000.0.51f1 + FMOD 2.03.08
They have issues with both MacOS and Windows FMOD Studio.
Any progress with investigating this issue? Anything I could provide from our side to help?
Kind regards,
Dario

Hi,
Thanks for the info. Would it be possible to test `2.03.09` and let me know if the issue persists?

Hello,
Not sure if this helps much, but after upgrading from 2.03.08 to 2.03.09 sound designer has reported that issue still occurs sometimes, but much more rarely.
Cheers,
Dario

FYI, our next release (2.03.11) will contain a few fixes for live update issues.
