如何同时播放声音？

jjj311

现在的情况是amarok播放音乐的时候Firefox打开豆瓣电台就放不了音乐了。。。
求解。。。是不是pulseaudio有问题呢？
我的kmix只有一个channel：Internal Audio Analog Stereo
声卡是Intel HDA
是不是alsa、oss、pulseaudio这几个USE的配置有问题还是？
这个问题困扰我好久了。。。

从来都是 -pulseaudio ，alsa混音也一直都工作得很好。

axlrose

pulseaudio 用了一下还不错，加上那个混音控制器，单独的软件音量控制
再说alsa不独占方式的话，也OK的啊
