某些应用程序的音频不起作用 - Ubuntu 20.04.06

我在某些应用程序中遇到了系统声音问题。它无法在某些特定安装的应用程序上重现任何音频（目前，我在通过 snap 安装的 Slack 和 Telegram Web-.AppImage 版本中遇到了这个问题）。其他同事也在 Ubuntu 上使用 Slack，没有遇到这个问题。

音频在通过 snap 安装的网络浏览器（Mozilla Firefox）、Spotify 和本地视频播放器上运行正常。

看起来与这些问题类似，但是他们没有得到任何有用的答案：

sudo lspci -v输出：

答案1

我按照以下步骤找到了解决方案。

  1. 首先，pavucontrol通过以下命令安装：
sudo apt-get install pavucontrol

  1. 打开它并运行pavucontrol。

  2. 转到Playback并在Show字段上选择Applications。

  3. 重现任何带有无法正常工作的音频的多媒体。pavucontrol应该显示正在重现的音频，它看起来应该像这样： pavucontrol 看起来显示了新的 Chromium 输出

  4. 如果扬声器按钮处于静音状态，单击该按钮即可取消静音。

希望这对你有帮助！
