Alexa Skill C＃不会播放音频

我有一个Alexa技能，我想在发布时播放一首歌 . 我正在使用VS2017与AWS Toolkit和AWS Lambda函数 . 我已经配置并构建了我的Alexa技能并发布了我的Lambda函数，并通过Alexa控制台测试和我的Alexa Echo验证了所有这些功能 .

当我从我的SkillResponse中的返回文本更改为使用AudioPlayerPlay（来自Alex.NET Nuget包）返回音频指令时，我得到了看似格式正确且正确的JSON，但是Alexa控制台测试说它是一个不受支持的设备和我的Alexa Echo什么也没做 .

这是AWS Lambda测试中的JSON .

{
  "version": "1.0",
  "response": {
    "shouldEndSession": true,
    "directives": [
      {
        "playBehavior": "REPLACE_ALL",
        "audioItem": {
          "stream": {
            "url": "https://music.amazon.com/my/albums/You+Get+What+You+Give/YOU+GET+WHAT+YOU+GIVE/ZAC+BROWN+BAND?ie=UTF8&albumAsin=B00438BTJ6&playNow=1&trackAsin=B004386MMU",
            "token": "scrumstartsong",
            "expectedPreviousToken": null,
            "offsetInMilliseconds": 0
          }
        },
        "type": "AudioPlayer.Play"
      }
    ]
  }
}

这是Alexa Console测试中对Directive：AudioPlayer.Play命令的输入

            }
        },
        "playBehavior": "REPLACE_ALL"
    }
}

我已经为令牌尝试了不同的（和没有）值 .

我已经通过让Alexa播放它来验证我可以访问我的Echo上的歌曲 .
