解决Linux系统下声卡独占的方法

A much better way of getting esd to work with non-esd-aware apps is to make alsa use its software mixer.

让alsa用它自己的软件混合器一个更好的方法来让esd和不是esd识别的应用程序在一起工作

$ sudo /etc/init.d/alsa-utils stop $ sudo gedit /var/lib/alsa/asound.state

(add the following text verbatim to the start of this file)

$ sudo /etc/init.d/alsa-utils start

# This text should be added to the beginning of

# /var/lib/alsa/asound.state. You only need to add

# it once -- it is saved across reboots.
