我的笔记本电脑上安装了 Kubuntu。音频无法正常工作。此外,我无法通过 HDMI 将其连接到外部屏幕,我找不到解决这些问题的任何帮助。昨天我安装了 Ubuntu 22.04。音频仍然无法正常工作。如果我转到音频设置,我可以看到 Youtube 视频中的音频级别(就像您在图片中看到的那样),但我听不到任何声音。如果我测试扬声器,我听不到任何声音。我关注了各种帖子,更新并重新安装了驱动程序,主要是在终端中复制命令行,但似乎没有任何效果。有人能帮帮我吗?
以下是命令 journalctl -k | grep -Ei "ALSA|HDA|sof[-]|HDMI|snd[_-]|sound|hda.codec|hda.intel" 的输出:
