I have been trying to set up a way to cast my weather. Everything works until I try to play any audio to a google mini. If I cast an audio from my web server, it all works, but nothing from the pi device, itself. I get the following in the debug panel:
Not able to load media:Load failed Not able to load the media.
Any help would be appreciated.

I see you are sending `http://10.10.7.6/home/mike/web/pi/tmp/wavenet_test.mp3` to the device.
Can you verify this file is available at that URL by putting the URL in a browser?
Also, is this IP accessible to the cast device?
A good test would be to click this \>\> [http://10.10.7.6/home/mike/web/pi/tmp/wavenet\_test.mp3](http://10.10.7.6/home/mike/web/pi/tmp/wavenet_test.mp3) \<\< on your phone or a tablet on the same SSID as the google cast device to verify is URL is accessible across your wifi.

You can also test the rest of the flow by replacing `"url":"http://10.10.7.6/home/mike/web/pi/tmp/wavenet_test.mp3`
with
`"url": "http://www.orangefreesounds.com/wp-content/uploads/2018/11/Ding-dong-doorbell-rings.mp3",`
and see if it works

10.10.7.6 is the pi that node-red is also on. I changed the permissions to 777 on the mp3 file just in case. My webserver is not local, but on a hosted machine. I tried the url above for the doorbells, and they work. The 10.10.7.6 from the statement above doe not. I have tried to place the mp3 file in different locations, from root /tmp , /data , home/pi/tmp , and others.
When I try to use a browser to get to [http://10.10.7.6/home/mike/web/pi/tmp/wavenet\_test.mp3](http://10.10.7.6/home/mike/web/pi/tmp/wavenet_test.mp3) , it shows not found. It's funny I can write an mp3 file to the system, but cannot read it

Do you have a web server running on port 80 hosting the file?
You do know you cannot just access via http without a web server right?
You can however, present the file via a http endpoint in node-red.

> I'm not certain what home-assistant has to do with this? I cant imagine what setting up a URL to host an MP3 has to do with anything outside of node-red. The first test in my mind is - can you access the MP3 in your browser? If you cant, then there is no way the cast device is gonna. On the same machine where node-red is running, what happens if you point your browser at [http://localhost:1880/endpoint/alavp](http://localhost:1880/endpoint/alavp) ? do you get anything?

Wellll, Something I never thought of. Time to remove the apache2 server. Thanks for all the help

Its really amazing what you can achieve with just node-red 🙂

You can also place the files in the http static folder of node-red, and the url would be `http://ip_of_node-red:1880/wavenet_test.mp3`

I assume that would only work if you have left your http endpoints unsecured.

And there-in lies the problem. I uninstalled apache2, but it still does not allow for reading of the file. I can be saved, just not read. I think I'll reinstall the OS on the Pi and start again.

I have tried all the solution provided. I cannot list an file under the 10.10.7.6:1880, or any folder in the .node-red folder.
I did something to foul this up. I added Peter Scargills' script a while back, and am starting to wonder if some setting, somewhere, has changed. I checked the settings.js, and all the settings are at default.

ok, follow this...
1. copy your mp3 to `~/.node-red` folder & name it `bell.mp3`
2. paste the below flow into node-red (ctrl+i)...
```auto
[{"id":"d5a6dd33.a0e28","type":"http in","z":"553814a2.1248ec","name":"","url":"/bell","method":"get","upload":false,"swaggerDoc":"","x":260,"y":1200,"wires":[["d59c8c4.b480d7","e7ed07e7.97da58"]]},{"id":"d59c8c4.b480d7","type":"file in","z":"553814a2.1248ec","name":"","filename":"bell.mp3","format":"","chunk":false,"sendError":false,"encoding":"none","x":500,"y":1200,"wires":[["87b9c5b8.526558","49056e53.5a32b"]]},{"id":"87b9c5b8.526558","type":"http response","z":"553814a2.1248ec","name":"","statusCode":"","headers":{"contentType":"audio/mp3"},"x":730,"y":1200,"wires":[]},{"id":"e7ed07e7.97da58","type":"debug","z":"553814a2.1248ec","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","x":370,"y":1240,"wires":[]},{"id":"49056e53.5a32b","type":"debug","z":"553814a2.1248ec","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"payload","targetType":"msg","statusVal":"","statusType":"auto","x":610,"y":1240,"wires":[]},{"id":"b72151a6.617e3","type":"cast-to-client","z":"553814a2.1248ec","name":"","url":"","contentType":"","message":"","language":"en","ip":"","port":"","volume":"","x":730,"y":1300,"wires":[[]]},{"id":"2dbcc2cc.94f80e","type":"inject","z":"553814a2.1248ec","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"{\"ip\":\"10.10.7.20\",\"url\":\"http://10.10.7.6:1880/bell\",\"contentType\":\"audio/mp3\",\"volume\":50}","payloadType":"json","x":250,"y":1300,"wires":[["b72151a6.617e3"]]}]
```
1. Double click the `INJECT` node & set ip / url accordingly...
e.g..
```auto
{
"ip": "10.10.7.20",
"url": "http://10.10.7.6:1880/bell",
"contentType": "audio/mp3",
"volume": 50
}
```
ip - this should be the ip of the google device
url - this should be ip of your PI
if you follow the above correctly, you should get the mp3 by clicking this \>\> [http://10.10.7.6:1880/bell](http://10.10.7.6:1880/bell) \<\<

You must not have the file in the right place.
Can you list your directory...
```auto
cd ~/.node-red
ls
```

changed settings.js to force userDir: /home/mike/.node-red just in case

I re-built the pi, with only node-red and a web server. With the mp3 files under /var/www/html/ directory, I can access those audio files
