virtualbox 用 alsa 找不到设备

isflyer

virtualbox的声音设备一直用的alsa，想想，昨天好像升级了几个模块好像是 qt  sdl 还要两个什么
现在虚拟的xp用oss有声音，用alsa确不行，希望得到大家的帮助

是升级sdl包的问题，以解决

isflyer

有没有什么办法能查到我昨天升级的模块？如果能，怎么还原呢？
谢谢

怎么降级呢？

coderoar

还原得用pacman -Q找出包的repo，再到你mirrorlist里设置的网站上手动下载老的包，用pacman -U安装。

谢谢你，我找到了mirrorlist，
其中一个 http://archlinux.unixheads.org/
可里面是的extra都是最新的呀，旧包不知道在哪里保存

coderoar

好像还真找不到了。

那个，virtualbox用alsa时能选择设备文件吗

isflyer

选择alsa时，启动会出现这个警告，用oss时正常


虚拟电脑运行可能碰到下面问题，您可以忽略这个信息，但建议您检查虚拟电脑设置以避免这个问题再次发生。

No audio devices could be opened.Selecting the null audio backend with the consequence that no sound is audible.

错误ID：HostAudioNotResponding
严重：警告

Same problem here with VirtualBox too, neither alsa nor oss working. Pops up "HostAudioNotResponding" error.

很郁闷，archlinux很爽，可就是软件更新后会出现奇怪的问题，今天又有好多要升级，都害怕了 呵呵;不过这里氛围很好
