推荐答案

否，这是不可能的.您能获得的最接近的是在用户系统上安装回送音频设备，例如OSX上的Soundflower，并将其用作默认音频输出设备.没有本地配置更改是不可能的.

No, this isn't possible. The closest you could get is installing a loopback audio device on the user's systems, like Soundflower on OSX, and use that as the default audio output device. It's not possible without local config changes.
