Hello,
I try to cast a song from my Jellyfin library to a Google mini with Home assistant but in log i have this error :

Additional information
I've made some test by command line :
~ catt -d 192.168.1.109 cast 'http://192.168.1.27:8096/Audio/d4b9c789040125ced2dc7b6e275b0962/universal?UserId=0943ef1a1eec410dbaeac7a5857d797c&DeviceId=f042a4873f36637f135601383905b2fb&MaxStreamingBitrate=140000000&api_key=<hidden>'
Casting remote file http://192.168.1.27:8096/Audio/d4b9c789040125ced2dc7b6e275b0962/universal?UserId=0943ef1a1eec410dbaeac7a5857d797c&DeviceId=f042a4873f36637f135601383905b2fb&MaxStreamingBitrate=140000000&api_key=<hidden>...
Playing "universal" on "Google mini"...
But no sound, but connection is OK
another test with broken api_key :
~ catt -d 192.168.1.109 cast 'http://192.168.1.27:8096/Audio/d4b9c789040125ced2dc7b6e275b0962/universal?UserId=0943ef1a1eec410dbaeac7a5857d797c&DeviceId=f042a4873f36637f135601383905b2fb&MaxStreamingBitrate=140000000&api_key=<broken_key>
ERROR: [generic] Unable to download webpage: HTTP Error 401: Unauthorized (caused by <HTTPError 401: Unauthorized>)
Error: Remote resource not found.
So it's the good server that answer
and last test :
~ catt -d 192.168.1.109 cast http://192.168.1.27:8096/Items/adb7a26ebda39ee2396ded4c2513d916/Download?api_key=<hidden>
Casting remote file http://192.168.1.27:8096/Items/adb7a26ebda39ee2396ded4c2513d916/Download?api_key=<hidden>...
Playing "Download" on "Google mini"...
And here the song was played
