我是 Ubuntu 新手，正在运行13.10在外星人 M14x R2. 笔记本电脑配有“英特尔 Panther Point PCH - 高清晰度音频控制器”声卡（我找不到 Linux 驱动程序）。运行cat /proc/asound/card0/codec* | grep Codec返回“Creative CA0132”，我认为它在 Windows 中被识别为“Soundblaster Recon3di”。当我插入耳机时，没有检测到音频设备，并且声音继续从扬声器播放。我尝试运行 alsamixer 来禁用自动静音，但没有自动静音选项。我还尝试将“snd-hda-intel position_fix=1”以不同的语法附加到 alsa-base.conf 文件中。我尝试使用模型参数，但没有列出任何选项这里似乎兼容的软件都可以使用（例如“alienware”、“laptop”和“dell-eq”）。此时，我已经用全新安装清除了所有内容，以排除我可能犯的任何其他新手错误。任何建议都将不胜感激。
不幸的是，我没有足够的声誉点来发布图片。这是alsamixer 的屏幕截图。
pulseaudio --check没有返回任何输出。

那里曾是这里有区别。当我不戴耳机运行该命令时，输出显示Client Index: 22在第 5 行。
感谢您迄今为止的反馈。据我所知，我的耳机没有问题；我在其他设备上也用过它们。
编辑：耳机插入耳机插孔后即可被检测到。声音设置将显示“耳机”而不是“扬声器”，并且插入耳机后会短暂出现破音，但扬声器会继续播放。
