插孔音频服务器最近停止在我的电脑上工作。我现在在网上搜索了大约2个小时,我找不到任何解决方案来解决我遇到的错误。这是错误日志:

如果有帮助,这是我的uname -a输出:

Linux Sean-Lappy 4.4.0-53-generic #74-Ubuntu SMP Fri Dec 2 15:59:10 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

我能想到的唯一冲突是我最近安装了LMMS并使用sudo apt-get autoremove删除了一堆旧内核

非常感谢任何帮助。

更新(2016年12月14日):

我还没有找到解决这个问题的方法。我在杰克的来源中挖掘并在JackLinuxFutex.cpp的第114或124行查明了错误

以下是完整的详细插孔输出:http://pastebin.com/1FbNwCJU

我也从源头安装千斤顶无济于事。

如果有人知道修复,那么考虑到我目前无法在笔记本电脑上使用任何音频设备,这将是非常好的。

1 个答案:

答案 0 :(得分:0)

我终于解决了这个问题。这是我使用的步骤:

  1. 卸载与声音相关的所有内容

    sudo apt-get purge jackd qjackctl cadence pulseaudio pulseaudio-module-jack alsa

  2. 重新启动

  3. 重新安装除插孔

    以外的所有内容

    sudo apt-get install alsa alsa-firmware-loaders alsa-tools alsa-tools-gui alsa-firmware alsa-utils pulseaudio pulseaudio-module-jack cadence

  4. 重新启动

  5. 下载并解压缩jack源代码

    sudo apt-get install unzip

    wget https://github.com/jackaudio/jack2/archive/master.zip

    unzip master.zip

  6. 安装依赖项

    sudo apt-get install libasound2-dev

  7. 使用--alsa标志

    从源代码编译插孔

    cd jack2-master

    ./waf configure --alsa

    ./waf build

    sudo ./waf install

  8. 我不知道这是不是最好的方法,或者它是否会在其他任何人的机器上运行,但我可以告诉你,jack现在已成功运行,我正在再次听音乐。
