几个星期以来，我在声音方面遇到了一些麻烦，只是在我的系统上没有产生任何输出。我尝试提交错误报告，但是启动板没有答案，错误的重要性尚未确定，并且未分配给任何人。我以前使用过Ubuntu 18.04，但声音没有问题。
因此，我决定重新安装Ubuntu，希望此问题得以解决，但这没有发生。我真的很想解决问题，但我不知道如何解决。我检查了很多东西并尝试了它们，但没有任何效果...
我尝试过的事情:
options snd-hda-intel dmic_detect=0添加到/etc/modprobe.d/alsa-base.conf blacklist snd_soc_skl添加到/etc/modprobe.d/blacklist.conf 我恳请帮忙。
我在下面发布相关输出:

/etc/libao.conf包含脉冲作为默认驱动程序(default_driver=pulse)$ systemctl --user enable pulseaudio.service pulseaudio.socket不产生任何输出$ systemctl --user status pulseaudio输出:但是仍然没有声音。
最佳答案
对于Pulseaudio
default_driver =脉冲
[或编辑或创建本地.libao(注意点作为第一个字符)文件，
主目录(将优先于系统范围内的/etc/libao.conf文件)
systemctl-用户启用pulseaudio.service pulseaudio.socket
检查脉冲音频:
systemctl --user status pulseaudio
据报道
speech-dispatcher有时会中断音频尝试编辑
/etc/default/speech-dispatcher将RUN=yes更改为RUN=no要么如果您不使用它，请将其删除。
另请参阅:https://askubuntu.com/questions/1218058/ubuntu-19-10-audio-driver-issue
通过编辑
