rso*_*oto 6 sound lenovo 20.04
我刚刚安装了 Ubuntu 20.04，除了声音之外，一切都运行得很好。奇怪的是，当音频被触发（由系统声音、静音/取消静音）时，会发出奇怪的蜂鸣声（听起来像是放气的东西）。当使用有线耳机时，只有静电。我猜蓝牙耳机可以工作是因为它是另一个接口？
我尝试过升级内核，我也研究了其他一些类似的问题，但似乎这是不同的。

看来您使用的驱动程序是sof-audio-pci. 据此，您可以尝试使用snd_hda_intel. 简单复制一下程序：
编辑grub
$ sudo gedit /etc/default/grub
改变
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
到
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash snd_hda_intel.dmic_detect=0"
更新grub
$ sudo update-grub
重启
您可以检查是否检测到声卡
$ aplay -l
如果这不起作用，如果您发布以下输出可能会有所帮助：
$ cat /proc/asound/cards
$ lsmod | grep snd
$ dpkg -L linux-modules-<kernel version>-generic | grep snd
$ inxi -SA
$ lspci -nnk | grep -A 4 Audio
$ uname -a
$ aplay -l
$ dpkg -l | grep alsa
$ grep intel /etc/modprobe.d/alsa-base.conf
