Bose Soundlink Mini II - 如何输出高品质声音？

我有一台运行良好的 Bose Soundlink Mini - 我可以将它与 Kubuntu (14.10) 配对，并将其设置为 Phonon 中视频的音频播放设备。听起来很棒。:)

我刚买了一台 Soundlink Mini II，现在遇到了麻烦。扬声器似乎没有通过蓝牙使用相同的高质量音频模式。听起来很糟糕。以下是摘录自

索引 1 是新款 Soundlink Mini II

正如您所见，新扬声器的样品规格仅为单声道@8kHz。:(

这是否意味着我需要设置 pulseaudio 以使用 A2DP 来支持此设备？我该怎么做？我很乐意编辑配置文件，但我不知道从哪里开始。

谢谢。

答案1

我在 Ubuntu 14.04 上使用 bose soundlink mini 2 时也遇到了同样的问题。当我安装 BlueDevil 程序并使用它连接到 bose 时，问题就解决了。建立连接后，您需要打开声音设置，然后您就可以切换到 A2DP 配置文件 ;-) 希望这会有所帮助，因为我不是计算机专家。祝你好运！
