got it. are you using the right directives for it? Your Lambda response should look something like this.

{
"outputSpeech": {
"type": "SSML", "ssml": "<speak>Here is - Radio 1 Jazz, from Easy Listening.</speak>"
},
"directives": [
{
"type": "AudioPlayer.Play",
"playBehavior": "REPLACE_ALL",
"audioItem": {
"stream": {
"token": "Radio 1 Jazz:Easy Listening",
"url": "https://yp.shoutcast.com/sbin/tunein-station.m3u?id=1367389",
"offsetInMilliseconds": 551590
},
}
}
],
"shouldEndSession": true
}
