audacity使用 录音时出现“打开声音设备出错，请检查输出设备的设置及采样率”怎么办呢？

许多朋友经常需要对一些音频进行编辑，但是被音频软件复杂的界面和昂贵的价格搞得无所适从 现在，可以试一试Audacity( /bencandy.php id=77下载安装安装环境为红旗桌面4.1plus，因为Audacity需要wxwindows支持，但是4.1plus并不带wxwindows所以需要单独下载 下载Audacity的linux版本源码包，下载wxwindows的rpm包wxGTK 2.4.2 1.i386.rpm wxGTK devel 2.4.2 1.i386.rpm（如果下载的版本高会需要glibc2.4支持，而plus自带的gilbc2.3.2，如果升级glibc那就太麻烦了） 安装wxGTK*.rpm，编译安装Audacity Audacity运行时可能会提示初始化音频I/0层的时候发生错误，您将无法播放或录制音频，这个问题可以从以下三方面分析：1 Audacity 运行前，其他程序不能占用声卡 2 调节采样率试一下 3 可能alsa驱动不行，请换oss驱动 我没有换oss驱动，但是最后搞好了 但怎么搞定的现在也没有明白 首先关掉gaim，firefox，终端等，关掉所有可能出声的程序，然后重新配置了一下声卡 最后可以正常使用了 测试了播放，肯定没有问题 录音也没有问题 感觉界面比较不错，功能还有待完善，不过现在完全能满足要求 网上对于初始化音频I/O失败的解释* If you get an error like this Error Initializing Audio: There was an error initializing the audio i/o layer. You will not be able to play or record audio. Error: Host error. then audacity cannot access your sound card. Audacity cannot use the audio i/o layer when it is in use by another application. If you are using Gnome, KDE or another window manager, be sure to disable the system sounds before starting Audacity.** If this still happens when nothing else is using audacity then you may have a sample rate selected that your card does not support. You can alter this by changing the Project Rate at the bottom left of the screen.** Another possibility is that somehow, the link to /dev/dsp, or its permissions, were changed without your knowledge by an unknown process. What you should do (as root) is:$ rm /dev/dsp ln s /dev/dsp0 /dev/dsp #also try /dev/dsp1,2,etc.$ chmod 666 /dev/dsp0$ chmod 666 /dev/dspIf you are using udev in the 2.6 kernel then you may need to alter /etc/ud
