Ubuntu 21.04新戴尔Inspiron 7700 AIO没有声音

Question

我刚刚买了一台新的戴尔Inspiron 7700 AIO电脑与第11代i7处理器。安装了Ubuntu21.04，它大部分工作正常。然而，我没有声音从内置扬声器，声音设置面板显示“虚拟输出”作为唯一的输出选择。

目前，我已经安装了一个蓝牙声音输出设备，并且正在成功地将它用于声音输出，但我更喜欢使用AIO内置的扬声器。

有什么我能查到的吗？

Ubuntu 21.04

内核5.11.0-36-通用

$ sudo lshw -C相关输出

修正是将以下内容添加到/etc/modprobe.d/alsa-base.conf并重新引导.
