音频问题,Ubuntu 16.04

我在运行 Ubuntu 16.04 的系统上丢失了音频。

编辑:重新启动后,我注销并再次登录后声音似乎可以正常工作。

试过:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get remove --purge alsa-base pulseaudio
sudo apt-get install alsa-base pulseaudio pavucontrol
sudo alsa force-reload
reboot

sudo apt-get install pavucontrol
sudo apt-get install pulseeffects

aplay -l返回:

观察:我必须pulseaudio --start先运行,然后才能成功运行pavucontrol。之后pavucontrol我可以在声音设置中找到音频卡,但之前找不到。已取消静音alsamixer。音频之前可以正常工作,但我摆弄键盘控件时丢失了它。声音在 Windows 中可以正常工作。

任何帮助将不胜感激。

干杯!Jarle
