Ubuntu中文论坛

前日，同学新买一台Compaq Presario CQ45-203TX，其请我帮她安装些常用软件，我劝说她使用Ubuntu，她同意了，于是卸载原装的Vista，改装Ubuntu，可安装好后，发现声卡不能工作。
花了2个小时进行系统升级，升级后问题依旧。
用lspci -v | grep -i audio检测，结果为：
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)
到这一步就不知道接下来该怎么弄了，请高手赐教。
解决方法见10楼链接

是不是音量小的问题

My laptop is compaq CQ45-124TX. I have installed ubuntu for nearly a month. But I still cannot fix the problem of sound.
The sound card really can work. But when I stop the play, it will always repeat the last piece of sound.

我重新安装了声卡驱动，已经有声音了，但也存在与阁下一样的问题，只要一停止Mplayer，就会一直重复最后一段声音，好烦~~
I re-install the sound card drivers, have a voice, but there are also the same with you, when stop Mplayer, it will always repeat the last paragraph of the voice, very vexed~ ~
而且使用Audacious、RealPlayer无法播放MP3等格式的音乐，Linux游戏也没有声音...
And the use of Audacious, RealPlayer, and so can not play MP3 music format, Linux has no voice of the game ...

Yes, I have searched the internet, it has been submitted to ubuntu as a bug. But I forget the web site now.

据说是由于BIOS的原因，可以下载

然后刷上

我的compaq cq40-101tu也是遇到声卡的问题。
我的问题是开机login就开始发出“咚咚咚”……不停！
当我开mp3歌是系统显示声卡在忙着……并叫我关掉相关的软件在执行mp3播放！

刷BIOS。我的是这样解决的

出了刷bios之外，还有没有别的方法？比如：update driver之类的。
刷bios我不在行……怕刷了死机就糟了！

啊？我还以为发了不刷机解决声卡的方法就没人翻这帖了，没想到还是有人进来啊~
