Ubuntu系统无声音,PulseAudio守护进程启动失败及权限异常问题求助
各位好,我在其他帖子里找不到这个问题的解决方案,现在Ubuntu系统完全没声音了,想请大家帮忙看看!
我已经卸载并重新安装了pulseaudio,但执行相关命令时仍然遇到报错:
- 尝试启动pulseaudio:
$ pulseaudio --start
返回错误:
E: [pulseaudio] main.c: Daemon startup failed.
- 尝试终止pulseaudio守护进程:
$ sudo pulseaudio -k
返回权限相关错误:
E: [pulseaudio] core-util.c: Failed to create secure directory (/home/louisro/.config/pulse): Permission denied E: [pulseaudio] main.c: Failed to kill daemon: Permission denied
我检查了系统中是否有pulseaudio进程在运行:
$ ps -ef | grep pulse
输出结果显示没有相关进程:
louisro 8703 3418 0 21:45 pts/10 00:00:00 grep --color=auto pulse
尝试查看音频设备信息时,提示pulseaudio守护进程未运行:
$ pacmd list-cards
输出:
No PulseAudio daemon running, or not running as session daemon.
我的硬件音频控制器信息如下:
louisro@-ThinkPad-T400:~/.config$ lspci | grep -i audio
输出:
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)
另外,我还尝试过彻底卸载并重新安装alsa-base和pulseaudio,但这会破坏系统参数,我不得不运行sudo apt-get install ubuntu-desktop来恢复系统。具体操作和报错如下:
$ sudo apt-get remove --purge alsa-base pulseaudio $ sudo apt-get install alsa-base pulseaudio $ sudo alsa force-reload
返回的卸载模块错误:
Unloading ALSA sound driver modules: snd-seq-midi snd-seq-midi-event snd-seq snd-rawmidi snd-seq-device snd-hda-codec-conexant snd-hda-intel snd-hda-codec snd-hwdep snd-pcm snd-page-alloc snd-timer (failed: modules still loaded: snd-hda-codec-conexant snd-hda-intel snd-hda-codec snd-hwdep snd-pcm snd-page-alloc snd-timer). Loading ALSA sound driver modules: snd-seq-midi snd-seq-midi-event snd-seq snd-rawmidi snd-seq-device snd-hda-codec-conexant snd-hda-intel snd-hda-codec snd-hwdep snd-pcm snd-page-alloc snd-timer.
希望大家能给我一些解决思路,谢谢!
