/dev/dsp: Device or resource busy

mystérieux

                                                                用realplayer播放了几个文件后，发现/dev/dsp被占用了，除非重启，否则再也放不出声音。
realplayer的提示如下
ALSA lib pcm_dmix.c:1008:(snd_pcm_dmix_open) unable to open slave
mplayer的提示如下

想把声卡驱动卸掉重装，但会报告驱动在使用中，为了找到原因，还是不要强行卸掉，搜索了一下外国人的论坛 www.linuxforums.org/forum ，上面有个贴子说是firefox 占用的，但我的firefox 上面没有开视频网页，而且关掉浏览器以后还是不行，后来用了lsof来查，先查的是dsp，无结果，后来又查了pcm，发现居然是scim占用了，
# lsof |grep pcm
scim-laun 4500       saga   13u      CHR     116,16       0t0       2777 /dev/snd/pcmC0D0p
scim-help 4504       saga   13u      CHR     116,16       0t0       2777 /dev/snd/pcmC0D0p
scim-pane 4505       saga   13u      CHR     116,16       0t0       2777 /dev/snd/pcmC0D0p
scim-brid 4507       saga   13u      CHR     116,16       0t0       2777 /dev/snd/pcmC0D0p
杀掉scim进程，声音恢复。
