答案1

根据我通过搜索internet找到的内容,你必须编辑alsa基础声音配置文件,并添加dell-s14dell-vostro-3500,因为只有两个选项可供选择,所以选择dell-s14

打开终端,并键入:


sudo touch /etc/modprobe.d/alsa-base.conf.bak


sudo cp /etc/modprobe.d/alsa-base.conf /etc/modprobe.d/alsa-base.conf.bak # backup alsa-base.conf


sudo nano /etc/modprobe.d/alsa-base.conf 



向下滚动到alsa-base.conf的底部,并将此新行添加到底部:


options snd-hda-intel model=dell-s14



按键盘组合键Ctrl+O,然后按Enter键保存对alsa-base.conf所做的更改,按键盘组合键Ctrl+X退出nano。

接下来运行以下命令:


sudo alsa force-reload 




答案2

我将用户添加到'audio'组,在重新登录后,修复。


usermod -a -G audio $USER



使用帐户列出:


aplay -l 



aplay: device_list:268: no soundcards found



它没有看到声卡,但当使用root (sudo )列出时:


aplay -l 



**** List of PLAYBACK Hardware Devices **** 


card 0: Intel [HDA Intel], device 0: ALC892 Analog [ALC892 Analog] 


Subdevices: 1/1 Subdevice #0: subdevice #0



看到它们了。


答案3


sudo modprobe snd-hda-intel




答案4

以下命令帮助我:


pulseaudio --kill


sudo alsa force-reload


pulseaudio --start




sudo alsa force-reload




答案5

这些都不适合我

我从http://12244.wpc.azureedge.net/8012244/drivers/rtdrivers/pc/audio/0001-LinuxPkg_5.18rc8.tar.bz2下载驱动程序,并安装它。

一切正常。
