我正在使用 Ubuntu 20.04,遇到了一个问题。无论使用哪种输出设备,只要启动 Ubuntu,声音就不起作用。这种情况发生在所有应用程序和网站中,所以我很确定声音驱动程序出了问题。为了有音频,我必须拔下设备并重新插入。这种情况在更新后开始发生,这也弄乱了我的图形(我现在已经修复了)。
编辑:我尝试卸载 alsa 和 pulseaudio,然后重新安装 alsa。现在我的问题已经解决,但又出现了另一个问题:我无法重新安装 pulseaudio,这意味着我无法访问声音设置,而且我的声卡似乎无法被识别。
安装 pulseaudio 时我收到的错误消息是:
sudo apt install pulseaudio

The following information may help to resolve the situation:
The following packages have unmet dependencies:
pulseaudio : Depends: libpulse0 (= 1:13.99.1-1ubuntu3.8) but 1:13.99.1-1ubuntu3.12 is to be installed
Depends: pulseaudio-utils but it is not going to be installed
Recommends: rtkit but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

好的,看来我的问题已经解决了。我订阅了仅限安全的软件包更新。更改此设置后,我只需升级软件包,pulseaudio 就会自动重新下载。对于我的第一个问题,我运行了以下命令:
rm -r ~/.config/pulse; pulseaudio -k
之后我重新启动并且所有端口的音频都能够完美识别。
(我在这篇文章中找到了上述命令:未检测到声音设备)
