怎么调整pc喇叭音量，或者静音？

我在办公室跑linux，使用TAB等，经常搞得机器乱响，影响别人工作，希望能得到解决办法。

PC speaker is enabled by default. This is not a bug but if you dont like this. There are two ways to circumvent the noise:

    * Reduce its volume to a acceptable level or completely mute the PC speaker in alsamixer with the setting for "C Speak".
    * As root user disable the PC speaker system wide by runing the following command in a console.

    modprobe -r pcspkr ; echo "install pcspkr :" >>/etc/modprobe.conf
