ubuntu 19.04更新后无法检测到声卡

我使用过软件更新。之后就没有声音了。花了几个小时阅读类似的问题后，我意识到它们（包括重新安装 alsa 和 pulseaudio）都对我不起作用。

使用

lspci -v | grep -A7 -i "audio"

我得到以下结果：

00:1f.3 Audio device: Intel Corporation Cannon Lake PCH cAVS (rev 10)
    Subsystem: Micro-Star International Co., Ltd. [MSI] Cannon Lake PCH
 cAVS   Flags: bus master, fast devsel, latency 32, IRQ 11  Memory at
 a4430000 (64-bit, non-prefetchable) [size=16K]     Memory at a4100000
 (64-bit, non-prefetchable) [size=1M]   Capabilities: <access denied>

 00:1f.4 SMBus: Intel Corporation Cannon Lake PCH SMBus Controller (rev
 10)
 -- 01:00.1 Audio device: NVIDIA Corporation Device 10f8 (rev a1)   Subsystem: Gigabyte Technology Co., Ltd Device 3fff     Flags: bus
 master, fast devsel, latency 0, IRQ 10     Memory at a4080000 (32-bit,
 non-prefetchable) [size=16K]   Capabilities: <access denied>

 01:00.2 USB controller: NVIDIA Corporation Device 1ad8 (rev a1)
 (prog-if 30 [XHCI])    Subsystem: Gigabyte Technology Co., Ltd Device
 3fff

看来，尽管声卡确实存在，但系统无法安装正确的驱动程序。以下https://help.ubuntu.com/community/SoundTroubleshooting 我尝试安装 snd-hda-intel 驱动程序但它返回：

sudo modprobe snd-hda-intel
modprobe: FATAL: Module snd-hda-intel not found in directory /lib/modules/5.0.0-29-generic

然后我去参观https://code.launchpad.net/~ubuntu-audio-dev/+archive/ubuntu/alsa-daily/+packages 但我不知道如何安装正确的 .tar.gz 作为驱动程序（可能是 oem-audio-hda-daily-dkms_0.201907080246~ubuntu19.04.1.tar.gz？）有人可以帮我解决这个问题吗？谢谢！

更新1 dkms status什么也没有返回。已尝试sudo apt update但upgrade无法解决问题。

以下是

lspci -knn | grep Audio -A3

返回：

它对我有用

以下是原文的副本希望者

sudo vim /etc/default/grub
Find GRUB_CMDLINE_LINUX_DEFAULT and add snd_hda_intel.dmic_detect=0 to the end 
of it. (ex: GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 
snd_hda_intel.dmic_detect=0")
sudo grub-mkconfig -o /boot/grub/grub.cfg
Reboot the system.
