[FZH] F16升级后的几个问题，主要是声音

[flyreach Lin]

大家好，我从fedora15升级到fedora16后遇到了几个问题，DVD.iso优盘升级安装，google和baidu后都没得到解决，麻烦大家看看
一、声音问题
    刚从F15升到16的时候声音没问题，前2天yum upgrade一下，升级了kernel，gnome3下的程序如mpg123、mplayer就没声音了
    gnome3的设置中都找不到声卡
    kde下的程序如juk，amarok和konqueror都能播放音频，也能找到声卡,yum reinstall pulseaudio无效
    alsaminer：ALSA lib pulse.c:229:(pulse_connect) PulseAudio: Unable
to connect: 拒绝连接

               cannot open mixer: 拒绝连接
    alsaminer -c 0 正常
     而且在tty2下，也就是纯命令行模式下会看到：
    1308.084261] ALSA sound/usb/clock.c:227 3:3:3: cannot set freq

     的错误输出

我的本是Dell xps M1210,带罗技的摄像头，我怀疑是摄像头的音频设备和声卡音频冲突了
这个问题出现之前摄像头程序可以使用，之后就提示找不到摄像头了
还有就是在fedora15的时候我就发现mpg123等程序播放音频明显爆音，而kde程序不会，amarok（xine和gstreamer后端）音质非常好，
上网搜索得知mpg123的口碑非常好，所以应该不是mpg的问题，我怀疑还是硬件识别的问题，不知道有了解这个问题的没有。
二、grub升级到grub2的问题
在grub的时候要想开机不进入Xwindows只要在kernel /vmliuz。。。后面加3就好，
升级到grub2后这个不行了，我试过在grub.cfg中加text和修改
/etc/default/grub中GRUB_CMDLINE_LINUX="quiet rhgb text"
后grub2-mkconfig -o /boot/grub2/grub.cfg都不行
三、gnome-shell问题
fedora15的时候就存在，用开源驱动能进入gnome-shell，yum install kmod-nvidia或yum install
akmod-nvidia后就只能进入备用模式
三种驱动都能识别显卡，nv go 7400
在gnome-shell下使用search就马上崩溃。。。
四、ibus-pinyin
ibus-pinyin无法使用ibus-sunpinyin正常

几个问题麻烦大家了，e文不好没法在FedoraForum.org上发。。。谢谢了。。。
