我的笔记本电脑是戴尔 Vostro 5490，在通过 Ubuntu 软件中心进行固件更新后，扬声器没有声音，但使用 USB 耳机/麦克风时可以听到声音。

我也尝试过重新安装 alsa 和 pulseaudio，但没有效果。
我尝试通过 Ubuntu 软件中心多次更新，但每次都会出现这种情况

Devices that were not updated correctly:
• System Firmware (1.3.0 → 1.23.0)
Devices that have been updated successfully:
• BC511 NVMe SK hynix 512GB (11001101 → 11004101)
如果我重新启动，我会看到 BIOS 版本是 1.23.0
我已经使用 live usb 启动了 ubuntu 22.04 或 23.04，但仍然有虚拟输出并且没有声卡。
有任何想法吗？

我能够使用此处提供的解决方案解决问题
https://askubuntu.com/a/1295435/1072868
添加 /etc/default/grub 如下：
GRUB_CMDLINE_LINUX="snd-intel-dspcfg.dsp_driver=1"
然后执行
sudo update-grub
