音频错误：intel/sof/sof-cml.ri 的直接固件加载失败，错误为 -2

请注意，此问题是关于 X1 Carbon 7th Gen 的第十代英特尔 ( Intel(R) Core(TM) i7-10710U)。部分x1c7配备第8代intel，会出现不同的问题；lshw报告：

00:1f.3 Audio device: Intel Corporation Device 02c8 (prog-if 80)

我的音频无法正常工作。我没有收到任何声音或设备检测。在5.6.0-1-amd64内核上，我遇到了一堆错误sof-audio-pci

$ sudo dmesg | grep -i 'sof-audio-pci 0000:00:1f.3'

似乎它正在尝试加载一个不存在的文件，我没有得到任何信息

locate intel/sof/sof-cml.ri

我在包裹里也没有看到这个firmware-intel-sound，

唯一显示它是虚拟的输出源。是否有可能使用在启动时生成此日志的 X1 Carbon 7th Edition 获得正常运行的声音？

答案1

固件现在位于固件软签名包裹：

apt install firmware-sof-signed

答案2

请注意，这适用于：

lspci -nn | grep -i audio
Audio device [0403]: Intel Corporation Device [8086:02c8]

然后您需要启用它并设置配置文件，如下所示。

pacmd set-card-profile alsa_card.pci-0000_00_1f.3-platform-skl_hda_dsp_generic HiFi

答案3

您可能使用的是不稳定的 Debian。最近版本的 Linux 内核（5.5 及更高版本）已调整声音驱动程序，使其需要固件，而以前不需要，这是一个错误。然而，Debian还没有打包固件并且已知固件包落后。从 Ubuntu 的软件包中提取固件不起作用，因为它的 ABI 与 Debian 内核不匹配，无论如何加载都会导致挂起。

您需要降级到 Linux 5.4，说服 Debian 开发人员修复这两个错误之一，向 Linux 发送补丁以使驱动程序在缺少固件时不会失败，或者使用备用声卡（例如，通过 Thunderbolt 基座）。

答案4

我今天使用此配置遇到了同样的问题：

主持人：外星人 m15 R6
操作系统：流行！_OS 20.04 LTS x86_64
核心：5.13.0-39-通用
中央处理器：第 11 代英特尔 i7-11800H

不像芬·奥鲁普·尼尔森对于我的情况，我下载了存储库https://github.com/thesofproject/sof-bin/

$ git clone https://github.com/thesofproject/sof-bin/

警告

就我而言，我缺少的是 sof-tgl-h.ri 固件，这就是我复制 v1.7 文件夹的原因。

我将所有驱动程序安装在正确的文件夹中：

$ cd https://github.com/thesofproject/sof-bin/
$ cd thesofproject

# I created the following folders because they did not exist in my installation

$ sudo mkdir /lib/firmware/intel/sof
$ sudo mkdir /lib/firmware/intel/sof-tplg

# I copied the contents of the following folders into the folders I just created

$ sudo cp v1.7.x/sof-tplg-v1.7/* /lib/firmware/intel/sof-tplg/
$ sudo cp -r v1.7.x/sof-tplg-v1.7/* /lib/firmware/intel/sof-tplg/

现在重启后一切正常！
