Hi,

I'm trying to set an audible warning for my vision application. I'm using the `system.util.playSoundClip` function to play a `.WAV` file. My question is: where do I need to save my `.WAV` file to ensure it can be played on all clients?

Currently, I'm using this function in an **On Change** tag **Client Event Script**. My `.WAV` file is located on the gateway, but the script is not working. I wonder if the issue is related to the file location.

Yes, Vision runs directly in the client, and expects to find the file there. You should use a project startup script that looks for the files you need locally, and if not there, use `system.util.sendRequest()` to retrieve the file bytes from the gateway and then write them locally.

Thanks for your reply.

I found the code below in an Ignition manual. I figured out how to save the WAV file into the project database, so now I can query the file from the database and play the sound on every client. I tested it, and it worked for me!

```python
# This code would pull a sound clip out of a BLOB field from a database,
# playing it asynchronously at half volume.
  
query = "SELECT wavBlob FROM sounds WHERE type='alert_high'"
soundData = system.db.runScalarQuery(query)
  
system.util.playSoundClip(soundData, 0.5, 0)

```

You probably should use a Named Query for that, with caching enabled, as all of your clients will make that same request every time that alarm fires.

You could also stash a [Sound Player](https://www.docs.inductiveautomation.com/docs/8.1/appendix/components/vision-components/misc/sound-player) component somewhere, e.g. on an always present docked window. The Sound Player embeds the audio directly inside the project, so as long as your audio file isn't too large it's a useful alternative if you want something without any external dependencies.
