I had a working setup and played a siren sound to my sonos from a local file in my www folder.
It stopped working and can get it to work anymore. When i got to the file with the file editor it says" ‘utf-8’ codec can’t decode byte 0x89 in position 490: invalid start byte"
Is stil normal and can someone check what they are seeing? I have also done a fresh install of HA and just added the file and same issue.
