![Ubuntu 20.04 上没有耳机音频](https://linux22.com/image/1194449/Ubuntu%2020.04%20%E4%B8%8A%E6%B2%A1%E6%9C%89%E8%80%B3%E6%9C%BA%E9%9F%B3%E9%A2%91.png)
我有一台运行 Ubuntu 20.04.1 的旧电脑,耳机里没有声音。我不确定扬声器输出是否有问题,因为我目前没有可用的扬声器来测试它。
我尝试过以下命令:
echo "options snd-hda-intel model=generic" | sudo tee -a /etc/modprobe.d/alsa-base.conf
alsamixer
sudo alsa force-reload
pulseaudio -k && pulseaudio -D
alsactl restore
sudo apt remove --purge alsa-base pulseaudio
sudo apt autoremove
sudo apt install alsa-base pulseaudio

-- 更新 -- 我升级到了 22.04 并应用了所有更新
在设置/声音/输出/输出设备中,唯一可用的项目是“虚拟输出”
我按照这里给出的说明进行操作: 从 21.10 升级到 22.04 后未列出声音输出设备
并运行以下命令:
sudo touch /usr/share/pipewire/media-session.d/with-pulseaudio
systemctl --user restart pipewire-session-manager
设置/声音/输出/输出设备已正确更新,但即使选择“耳机 - 内置音频”也没有声音。
接下来,我运行了以下命令:
pulseaudio --kill && pulseaudio --start
sudo alsa force-reload
sudo alsactl restore
没有成功。
