我想问一下，我该如何调整扬声器的声音。现在声音听起来很刺耳，就像是从一个锡罐里发出来的声音。在 Windows 中，我没有遇到任何问题，但在 Ubuntu 中，声音听起来很糟糕。
为了寻找解决方案，我花了大约六个小时。我尝试重新安装 alsa 驱动程序，调整 alsamixer 中的设置，还尝试重新启动 pulseaudio。但对我而言，这些都不起作用。
当音轨（声音）中有人说话声音大一点时，可以听到关闭的声音。当有人正常说话时，情况会好一点，当我降低音量时，声音听起来更不刺耳，但仍然可以听到。
你有什么建议吗？
我在配备 Intel Core i3 的联想 Ideapad U510 上遇到了这个问题。我正在运行 Ubuntu 14.04。

您可以尝试使用终端的 alsamixer。您可以更改频道类型并更改扬声器的音量。
