![声卡突然无法被识别](https://linux22.com/image/903987/%E5%A3%B0%E5%8D%A1%E7%AA%81%E7%84%B6%E6%97%A0%E6%B3%95%E8%A2%AB%E8%AF%86%E5%88%AB.png)
就在一个小时前,声音还正常工作,我挂起了笔记本电脑,当我回来时,我不再有声音,并且我的声卡也无法被检测到。
Ubuntu 18.04,Thinkpad E570。我尝试使用耳机插孔和内置扬声器。
我将总结我已经尝试过的步骤(大致按时间顺序):
第一的:
pulseaudio -k && sudo alsa force-reload
然后重新启动。没有影响。
第二:
sudo apt remove --purge alsa-base pulseaudio
其次是
sudo apt install alsa-base pulseaudio && sudo alsa force-reload
并重新启动。没有影响。
第三:
sudo apt install build-essential linux-headers-'uname -r' alsa-base alsa-firmware-loaders alsa-oss alsa-source alsa-tools alsa-tools-gui alsa-utils alsamixergui
重启,无影响。
然后尝试安装驱动程序这里,重启,无影响。
希望有帮助的输出:
