我有一台 HP All-in-one（HP Pavilion All-in-One 24-xa0xxx），除了内置扬声器之外，一切似乎都可以在 Linux 上运行。耳机插孔工作正常。我正在运行 Arch Linux，但这并不是因为 Arch，因为它在 Ubuntu 上不起作用。我尝试过编辑该文件，/usr/share/pulseaudio/alsa-mixer/paths/analog-output-speaker.conf但几乎没有任何作用。上pavucontrol，它只是说Speakers (Unavailable)。我也尝试过编辑/etc/modprobe.d/alsa-base.conf，但也无济于事。现在我有一些 USB 扬声器，它们工作正常，但很麻烦，因为它们占用了额外的 USB 插槽并且声音更差。任何帮助将不胜感激。所有教程或论坛帖子都没有帮助，而且答案也多种多样。
