使用 Debian sid 升级到 4.18 Linux 内核后，我一直在处理一些升级前没有的声音问题。笔记本电脑挂起后，大多数时候（但并非总是）声音不起作用。我要么必须完全关闭机器，要么使用killallpulseaudio/pulseaudio--k命令，这些命令只有在我执行六次后才起作用。

另一个最令人恼火的问题是，当使用 pavucontrol 将输出设备从扬声器切换到耳机然后再切换回扬声器时，音量完全混乱。声音变得非常响亮且语无伦次。当我在 alsamixer 中取消静音和静音耳机输出时，也会发生同样的情况。
猫 /proc/asound/cards:
0 [broadwellrt286 ]: broadwell-rt286 - broadwell-rt286
HP-HPSpectrex360Convertible--802D
1 [HDMI ]: HDA-Intel - HDA Intel HDMI
HDA Intel HDMI at 0xb2210000 irq 48
答案1
我通过编辑解决了这个问题
/etc/default/grub
在下面一行我有
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
保留该行上的任何命令，但将其添加到引号内
acpi_backlight=vendor acpi_osi='!Windows 2013' acpi_osi='!Windows 2012'
这就是我正在使用的
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor acpi_osi='!Windows 2013' acpi_osi='!Windows 2012'"
然后
sudo update-grub
之后我的声卡名称改变了
0 [HDMI ]: HDA-Intel - HDA Intel HDMI
HDA Intel HDMI at 0xb2214000 irq 49
1 [PCH ]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0xb2210000 irq 46
我不再收到任何系统日志错误，并且在暂停后我的音频仍然有效，但是出现了一个问题，那就是插入耳机后扬声器输出不会恢复到原始音量。耳机已静音，但扬声器保持为 0，这意味着即使禁用自动静音，您也必须手动转到 alsamixer 并将其调高。解决这个问题的一种方法是
/usr/share/pulseaudio/alsa-mixer/paths/analog-output-headphones.conf
和编辑
[Element Speaker]
switch = off
volume = off
到
[Element Speaker]
switch = off
volume = merge
现在到目前为止一切都很好。
