mplayer使用alsa播放wma音频文件时很卡

mplayer -ao alsa *.wma时，声音很明显的有一些停顿，还有一些错误信息：

如果用mplayer -ao oss *.wma就没有问题，这是怎么回事？
intel板载的声卡。

干嘛要用MPlayer搞这个？xmms、bmp、amaroK才是“专业”干这个的……

win32codecs中的wma引擎不好，建议使用xine引擎。

vlc 也不错

反正我现在用kaffeine播放什么文件都没问题。当然，加密的文件肯定是没法放了。

我喜欢在terminal下听，再开多个标签，这样容易隐藏
用mpg123等遇到rm或者wma,asf之类的就不行了，所以习惯用mplayer。
现在就是奇怪为啥放wma的时候用alsa卡，用oss或者sdl都问题。怀疑是不是驱动的问题。
