Pulseaudio扬声器无声音

Mikicat 发表于 Dev

米奇卡特

好吧，我知道那里也有类似的问题，但是他们的答案都没有真正解决我的问题。我正在运行Debian 10（uname -a: Linux msi-debian 4.19.0-6-amd64 #1 SMP Debian 4.19.67-2 (2019-08-28) x86_64 GNU/Linux）

问题是，即使麦克风和耳机正常工作，我也无法使扬声器播放声音。

另一方面，当扬声器静音时，系统会检测到它们。这是有关我的计算机的信息：

我已经尝试了所有可能的配置文件组合pacmd set-profile-card，但我不知道该怎么做。此外，通过alsamixer检查，没有扬声器被静音（或者我没有一个被静音）：

Looks like it might be the same bug that is known in Ubuntu also:

https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1812693

This wiki has a suggestion for a workaround:

https://blog.kafaiworks.com/posts/arch-linux-audio-setup-on-msi-gp63/

The workaround is to edit the /usr/share/pulseaudio/alsa-mixer/paths/analog-output-speaker.conf file like this:

[Element Headphone]
switch = off
volume = merge
override-map.1 = all
override-map.2 = all-left,all-right

[Element Speaker]
required-any = any
switch = mute
volume = off

and then to restart pulseaudio (in Debian 10 it's implemented as a systemd per-user service):

systemctl --user restart pulseaudio.service

If I understand the workaround correctly, it looks like the volume/mute controls for the front speakers and headphones may be somehow miswired/cross-connected.

The hdajackretask tool in package alsa-tools-gui might be helpful too: if you can find working override settings for your laptop model, you should probably contact the Linux audio driver developers to report your findings, so the override can be made to apply automatically to that particular system model.

MSI GL73显然使用相同的ALC1220声音编解码器，并且在声音路由方面也需要与Clevo P950相同的修复程序。作为一个疯狂的猜测，您可以尝试添加一个/etc/modprobe.d/sound-fixup.conf包含以下内容的文件：

options snd-hda-intel model=clevo-p950

然后update-initramfs -u以root用户身份运行，以确保所做的更改也将在早期引导中生效，然后重新引导并查看是否带来了改进。如果MSI已将您的模型与GL73接线相同，则可能会解决该问题。如果不是，请删除该/etc/modprobe.d/sound-fixup.conf文件，然后update-initramfs -u再次运行以完全摆脱该选项。
