系统声音/ gnome shell(不播放或弹出);应用程序声音正常;

系统声音/ gnome shell(不播放或弹出);应用程序声音正常;

软件版本

Ubuntu:20.04.1

GNOME 版本:3.36.3

脉冲音频: 13.99.1

ALSA:k5.4.0-48-通用。

问题的问题/症状

  1. 系统声音/gnome shell 声音无法播放或者发出噼啪声/爆裂声,例如在终端中按 ESC
  2. 进入正常设置/声音时 - 单击每个扬声器上的测试按钮均无响应。既无视觉响应,也无音频响应;
  3. 正如问题标题所示,正常的应用程序内声音工作正常,例如 Chrome、VLC 和 Rhythmbox 等

背景/历史

这些问题出现的时间相对较近,是在上周发生特定事件之后。有一些更新(不知道是什么软件包/库)之后,我的板载声音无法正常工作。以前也发生过这种情况,但基本上运行alsa force-reload就可以解决问题。这次没有。除板载音频设备外,所有其他 USB 和 HDMI 声音设备都工作正常。我尝试了几种方法,从重新安装 Pulse 和 ALSA 开始。没有奏效,过了一段时间,我开始考虑可能是硬件坏了,并启动了 Windows 以检查它是否还能在那里工作;它确实可以工作!!!重新启动 Ubuntu 后,它奇迹般地工作了。然而,上述症状已经出现。从那时起,我尝试了解决方案这个问题没有成功。

答案1

在音频配置面板中,有一个名为“系统声音”的选项。这似乎很明显,但你有没有激活它?你可以尝试:

sudo killall pulseaudio; pulseaudio -k; sleep 10; pulseaudio --start

然后转到设置并确保输出到正确的设备(HDMI 显示器、前置或后置计算机插孔)。

顺便说一句,我建议你提到的原始帖子有一个错字。

sudo sed -i 's/SOUND_POER_SAVE_CONTROLLER=Y/SOUND_POER_SAVE_CONTROLLER=N/' /etc/default/tlp

应该:

sudo sed -i 's/SOUND_POWER_SAVE_CONTROLLER=Y/SOUND_POWER_SAVE_CONTROLLER=N/' /etc/default/tlp

我添加了一条评论,希望他们能够解决。

否则,它不会禁用声音中的省电功能。

干杯
