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. [{"id":"43091b5c.d97da4","type":"tab","label":"Flow 2","disabled":false,"info":""},{"id":"a17b9ea9.6a949","type":"cast-to-client","z":"43091b5c.d97da4","name":"","url":"","contentType":"","message":"","language":"en","ip":"10.10.7.20","port":"8009","volume":"50","x":800,"y":140,"wires":[[]]},{"id":"24563bf6.d167e4","type":"inject","z":"43091b5c.d97da4","name":"Play","props":[{"p":"payload","v":"","vt":"date"},{"p":"topic","v":"","vt":"string"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"","payloadType":"date","x":250,"y":140,"wires":[["3f5f4775.a5e218"]]},{"id":"3f5f4775.a5e218","type":"trigger","z":"43091b5c.d97da4","name":"tts + reset volume","op1":"{\"url\":\"http://10.10.7.6/home/mike/web/pi/tmp/wavenet_test.mp3\",\"contentType\":\"audio/mp3\",\"volume\":70}","op2":"{\"volume\":50}","op1type":"json","op2type":"json","duration":"7","extend":true,"overrideDelay":false,"units":"s","reset":"","bytopic":"all","topic":"topic","outputs":1,"x":540,"y":140,"wires":[["a17b9ea9.6a949"]]}]

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 << 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 , 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.

try this [image] How to cast videos General 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 ? do you get anything? PS - it works for me...

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 :slight_smile:

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 [image] Configuration : Node-RED

[image] E1cid: You can also place the files in the http static folder of node-red, 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.
