新的 22.04 安装无法在扬声器上播放声音

  • 772

我全新安装了 Ubuntu 22.04。Bang & Olufsen 扬声器不播放声音。

我已经浏览过https://help.ubuntu.com/stable/ubuntu-help/sound-nosound.html.en但没有任何帮助。

我可以通过耳机听到声音，但是当我拔出耳机时，即使音量设置为最大，声音也消失了。

Speaker - sof-hda-dsp在设置中显示为已识别，但未使用。当我拔出耳机时，Output device开关。

sudo lspci -v给出：

00:1f.3 Multimedia audio controller: Intel Corporation Device 51ca (rev 01)
    Subsystem: Hewlett-Packard Company Device 8bdd
    Flags: bus master, fast devsel, latency 32, IRQ 204, IOMMU group 15
    Memory at 601d1d0000 (64-bit, non-prefetchable) [size=16K]

    Kernel driver in use: sof-audio-pci-intel-tgl
    Kernel modules: snd_hda_intel, snd_sof_pci_intel_tgl

同样，我有一台旧笔记本电脑，其设置几乎相同，实际上可以工作：

lspci -v | fgrep -m1 -A19 '00:1f.3'

给出

   00:1f.3 Multimedia audio controller: Intel Corporation Comet Lake PCH-LP cAVS
    Subsystem: Hewlett-Packard Company Comet Lake PCH-LP cAVS
    Flags: bus master, fast devsel, latency 32, IRQ 154
    Memory at b431c000 (64-bit, non-prefetchable) [size=16K]
    Memory at b4000000 (64-bit, non-prefetchable) [size=1M]
    Capabilities: [50] Power Management version 3

    Kernel driver in use: snd_hda_intel
    Kernel modules: snd_hda_intel, snd_sof_pci_intel_cnl

也许切换正在使用的内核驱动程序是关键？如果有帮助的话，我该怎么做？

声卡未检测到并且命令sudo apt-get install build-essential linux-headers-uname -r alsa-base alsa-firmware-loaders alsa-oss alsa-source alsa-tools alsa-tools-gui alsa-utils alsamixergui没有解决问题。

如何为 HP 笔记本电脑安装 Bang and Olufsen 音频驱动程序？未能解决我的问题。

ubuntu（及其变体）上带有 sof-hda-dsp 音频的耳机没有声音也失败。

当耳机连接或断开连接也没有帮助时，音频输出不会切换。

Ubuntu 20.04 - 没有声音也失败

cat /proc/asound/cards产生以下输出：

 0 [sofhdadsp      ]: sof-hda-dsp - sof-hda-dsp
                      HP-HPEnvyLaptop17_cw0xxx-Type1ProductConfigId-8BDD



sudo gedit /etc/modprobe.d/alsa-base.conf

并添加

options snd-hda-intel model=generic

正如建议的Ubuntu 20.04 - 没有声音也失败了。

按照未检测到声卡 - Ubuntu 20.04 - sof-audio-pci 的建议使用 sof-bin也失败了。

我也得到了

[    0.475866] pci 0000:00:07.0: DPC: RP PIO log size 0 is invalid
[    0.476486] pci 0000:00:07.2: DPC: RP PIO log size 0 is invalid

在启动过程中。这是否与我的扬声器不工作有关？

我也做了标准sudo apt update && sudo apt upgrade但无济于事。

当我 grep 中的音频时dmesg：

我也尝试添加snd-intel-dspcfg.dsp_driver=1，/boot/grub/grub.cfg但没有改变任何东西https://bbs.archlinux.org/viewtopic.php?id=275737

cat /proc/asound/cards给出输出：

                      HP-HPEnvyLaptop17_cw0xxx-Type1ProductConfigId-8BDD

sudo aplay -l

给出输出：

如何让扬声器发出声音？

  1. Best Answer

    事实证明，这是一个众所周知的问题，目前还不容易解决。详细信息请参见此处。该帖子中提到的笔记本电脑是 HP ENVY x360 15-ey0xxx，它也使用 Bang & Olufsen 扬声器。这篇问答帖子非常活跃，截至撰写本文时的最新回复日期为昨天（2023 年 7 月 25 日）。我做了一些挖掘，似乎你有两个选择：

    1. 如此回复所示，将您的 Linux 内核版本更新到 6.3.2 。为此，您可以按照此处的说明进行操作。但是，正如这些答案中所解释的，不建议这样做。因此，您可能需要安装非 LTS 版本的 Ubuntu，例如发布的 23.04 或 23.10。
    2. 正如此回复中所指出的，您可以按照此处的说明安装可修复该问题的 DKMS 模块。但是，对于此选项，请注意回复下的以下警告极其重要：
    Thanks for the patch, but note that this change can't be taken.
It's dangerous and may burn speakers on other machines that don't use
this configuration.

For now, those info relies on the BIOS ACPI setup with _DSD entry, and
vendors should fix it with BIOS updates.

There have been already discussions how to deal with vendors who don't
cooperate well.

    我认为这两个选项都不理想，我个人会等到这个问题在 Ubuntu 的未来版本中得到解决。
