debian下解决mplayer没有声音的问题

liuwantao

本人是菜鸟,今天遇到了一个让我手足无措的问题:打开mplayer,奇怪竟然没有声音,捣鼓了半天还是不行,最后只有上论坛来求助,谢天谢地,得到了本版斑竹的帮助,顺利解决!现将解决过程整理如下,以备象我一样的菜鸟遇到同样问题能够顺利解决,也不用麻烦大侠们,让他们解脱出来去解决那些真正有难度的问题!!
1.发现播放电影竟然没有声音.
终端输出为:==========================================================================
It seems there is no Xvideo support for your video card available.
Run 'xvinfo' to verify its Xv support and read DOCS/HTML/en/video.html#xv!
See 'mplayer -vo help' for other (non-xv) video out drivers. Try -vo x11
==========================================================================
Opening video decoder: [realvid] RealVideo decoder
opening shared obj '/usr/local/lib/codecs/drvc.so'
Selected video codec: [rv3040] vfm:realvid (Linux RealPlayer 10 RV30/40 decoder)
==========================================================================
Building audio filter chain for 44100Hz/2ch/s16le -> 0Hz/0ch/??...
[AO OSS] audio_setup: Can't open audio device /dev/dsp: Device or resource busy
ao_nas: init(): Can't open nas audio server -> nosound
AO: [null] 44100Hz 2ch s16le (2 B/s)

2.执行命令xvinfo
显示:
X-Video Extension version 2.2
screen #0
no adaptors present

大家注意最后一行:no adaptors present

3.执行命令fuser
输出为:/dev/dsp:             3346

4.运行top找到3346

5.用kill 3346

到此开启mplayer,发现有声音了.
也许大家会认为这只是很简单的问题,是的现在我也觉得它很简单,但是今天上午发现这个问题的时候我真的一点头绪都没有,我还以为要重新配置声卡呢!!我写这篇帖子的目的只是想给跟我一样水平的人一点点帮助!同时也感谢斑竹法师给我的帮助.谢谢!
