Hi guys
I have some problem in Ubuntu sound card since I upgraded the latest 4.4.0-128-generic version of the Ubuntu kernel.
Here is my computer’s information:
Linux home 4.4.0-128-generic #154-Ubuntu SMP Fri May 25 14:15:18 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

HDA Intel PCH at 0xef220000 irq 130
My computer worked well until the kernel was upgraded, after upgrading the kernel to Linux 4.4.0-128-generic, while I start the computer, sound card is unable to work(there is nothing in sound setting output
).
I try to restart alsa, but:
sudo alsa force-reload
[sudo] password for jay:
Unloading ALSA sound driver modules: snd-hda-codec-hdmi snd-hda-codec-realtek snd-hda-codec-generic snd-hda-intel snd-hda-codec snd-hda-core snd-hwdep snd-pcm snd-seq-midi snd-seq-midi-event snd-rawmidi snd-seq snd-seq-device snd-timer (failed: modules still loaded: snd-hda-codec-hdmi snd-hda-codec-realtek snd-hda-codec-generic snd-hda-intel snd-hda-codec snd-hda-core snd-hwdep snd-pcm snd-timer).

Then I try to reinstall the driver modules in Ubuntu like this:
sudo apt-get -y --reinstall install linux-sound-base alsa-base alsa-utils lightdm ubuntu-desktop linux-image-`uname -r` libasound2
And killall the process
sudo killall pulseaudio
The sound card began normal work now.
Also I founded a lot of error log in /var/log/kern.log like this:
Jun 16 14:47:57 home kernel: [ 3494.077340] pcieport 0000:00:1c.0: AER: Corrected error received: id=00e0
Jun 16 14:47:57 home kernel: [ 3494.077357] pcieport 0000:00:1c.0: PCIe Bus Error: severity=Corrected, type=Physical Layer, id=00e0(Receiver ID)

Jun 16 14:47:57 home kernel: [ 3494.077372] pcieport 0000:00:1c.0: [ 0] Receiver Error
So is this the reason for my device or some bugs in the kernel driver?
