Ubuntu 22.04
我在笔记本电脑上使用Razer Blade 14 (2022)
。当通过音频插孔连接外部扬声器时,无论我将系统音量设置得多大,也无论我在系统设置中设置了哪种音频输出,我都会一直听到这种持续不断的响亮噪音。(例如,如果我将音频输出设置为笔记本电脑扬声器:我会从笔记本电脑扬声器听到正常声音 + 从外部扬声器听到噪音。)
以下是一些观察结果:
- 当我启动
Windows
这台机器时,音频插孔工作正常。但是,当我关闭连接音频插孔的机器时,噪音就出现了。 - 当我拔掉电源时,噪音发生了一些变化,但仍然存在。(电源将高频噪音添加到已经存在的低频嗡嗡声中。)
pulseaudio.service
当我禁用和时,会出现噪音pulseaudio.socket
- 当我在 GUI 中更改电源设置时出现噪音(
Power Mode
,Power Saving Options
) - 如果我切换到音频插孔输出,那里什么都没有播放,无论扬声器的音量有多大,我都听不到任何噪音(我通过外部旋钮调整扬声器音量)
Headphones - Family 17h (Models 10h - 1fh) HD Audio Controller
当扬声器插入音频插孔时,就会有输出。

注意:我通过 USB 转 SATA 连接器从外部 SSD 启动。这个特定的操作系统最初没有安装在 Razer 机器上。我最初将它安装在另一台台式机上。现在我无法使用那台机器,但我需要在磁盘上创建环境来工作,所以我只是取出 SSD 并将其插入我的笔记本电脑。现在无法进行全新安装。
