The*_*ark 5 audio macintosh intel
我的 2019 iMac (18,3) 在运行 Linux 时通过扬声器/耳机没有声音，也没有麦克风：它在 OSX 上按预期工作。
我在这里发帖是因为这似乎是一个 Linux 问题，因为我安装了三个不同的发行版——Manjaro（内核5.6-x86_64（虽然我也尝试过 6.0））；Fedora 31（内核5.1.20-300）；和Ubuntu 19.10（内核5.3.0-45-generic）——它们都没有产生声音或从麦克风录制。
该Audio Device从lspci是Intel Corporation 100 Series/C230 Series Chipset Family HD Audio Controller (rev 31)。它似乎还控制 PCI 桥接器和 USB 控制器。我在这里发布了更多信息。
我已经查看了pavucontrol和alsamixer，但没有发现任何迹象表明操作系统认为音频设备无法正常工作。只是没有发出声音。在 中pavucontrol，Configuration设置为 HDMI 关闭，并且Built-in Audio作为Analog Stereo Duplex- 尽管它们都不会改变结果。在 中alsamixer，Chip 标识为Cirrus Logic Generic，这是不正确的，并且除了 PCH 之外没有扬声器/耳机/任何列。
正如此线程中所建议的，我尝试/etc/modprobe.d/modprobe.conf通过添加options snd_hda_intel model=intel-mac-auto和其他各种迭代来解决（例如，options snd_hda_intel model=imac27请参阅此处了解原因）。安装 XFCE 并修改那里的设置对我不起作用。
有一些关于听不到较新（2017 年后）iMac 声音的类似帖子，最好通过在 Google 上搜索snd-hda-intel imac 18,3. 问题跨越所有发行版（Fedora；LinuxMint；Ubuntu；Manjaro）表明内核或驱动程序问题。
任何想法（A）如何修复或（B）我可以在哪里发布这个让某人将此音频设备构建到内核中？
添加dmesg. 最近没有journalctl与声音相关的条目。这是针对运行 5.6.5-1-MANJARO 的 Manjaro 20.0。
