Bose Revolv Soundlink USB 输出无声音

Bose Revolv Soundlink USB 输出无声音

我正在尝试通过 USB 让 Bose Revolve Soundlink 工作(蓝牙和 AUX 工作正常)。在 Windows 上通过 USB 使用它也可以正常工作。

扬声器被正常检测到,但是当我更换到正确的输出设备时却没有声音。

我有两个输出配置文件可以在pavucontrol“模拟立体声”和“数字立体声 (IEC958)”之间切换。它们都不起作用。

我已尝试重新启动。

任何帮助都将受到赞赏。

答案1

对于遇到同样问题的人,我解决了自己的问题。

编辑/etc/pulse/daemon.conf并添加:

default-sample-format = s16le
default-sample-rate = 48000

我认为这里最重要的部分是将采样率设置为 48000。

另一个奇怪的提示:选择模拟配置文件后,只有音频确切地100%。一个好的测试方法是运行命令aplay /usr/share/sounds/alsa/Front_Left.wav
