Hi,  
I’m using the code below to forward to Audio to FMOD and it works as espected.  
[https://www.fmod.com/docs/2.02/unity/examples-video-playback.html](https://www.fmod.com/docs/2.02/unity/examples-video-playback.html)

My issue is that I’m unable to reset fmod correctly and being it able to reproduce another video after the first. (The audio is muted the second time)  
How do I reset everything?  
For every video I repeat the init process, but it doesn’t seem to work.

Hi,

What version of FMOD Integration are you using?

When you mention `reset` are you shutting down the FMOD system ([FMOD Engine | White Papers - Getting Started](https://fmod.com/docs/2.02/api/white-papers-getting-started.html#shut-down)) or would it be possible to see the code you are using to reset your system?

Would you be able to expand on the init process you are using as well?

```auto

            Player.Play();

//on stop (loop reached)
            Player.Stop();
            fmod_mChannel.stop();
            fmod_mSound.release();

Hi,

Thank you for that.

When you are trying to play the second time are you seeing any FMOD errors in the console with the FMOD Integration logging level set to `Warning`:  
 ![image](https://canada1.discourse-cdn.com/flex036/uploads/fmod/original/2X/4/48d346abb72d0059c30e32620304cd151ffbf1d1.png)

It may be an issue with the sound or channel.

If you have followed our scripting example I would suggest adding some `FMOD.RESULT` checks ([FMOD Engine | Core API Reference - Common](https://fmod.com/docs/2.02/api/core-api-common.html#fmod_result)) which will also provide some more information where it is failing. Most FMOD functions will return an `FMOD_RESULT`.
