我在 Ubuntu 14.04 上安装了 Logitech C270 网络摄像头,用于 Skype (4.3.0.37)。网络摄像头视频播放完美,但声音总是需要大约 5 分钟和/或其他一些事情才能正常工作。
我发现声音起作用了一次:
- 我进入了 Skype 选项->视频设备 - 这将打开网络摄像头的绿灯
- 我进入声音设备,打开 PulseAudio 设置,更改网络摄像头的音量或点击其他任何按钮
- 仍然会存在至少 2 分钟的等待时间延迟。
我不能使用这个答案:罗技 c270 网络摄像头和 Skype由于网络摄像头未出现在音频设备中,因此只有 pulseaudio 出现。

我不确定我是否在 wine 中运行 skype。查看 ps -ef 的输出:
ps -ef |grep skype

我甚至看不到这里的网络摄像头?
有什么想法可以让我进一步诊断这个问题吗?
答案1
首先,我建议你使用Linux 版 Skype而不是葡萄酒。
Wine 是一个模拟器。因此,从网络摄像头捕获音频时出现高延迟是意料之中的事情。
其次,确保您的麦克风音量不超过%100。
第三,确保阿尔萨米克斯捕获供给左、右零。
