Comment 60 for bug 1875199

@Kai-Heng,

Short version - Audio output is now working properly using the test kernel you provided. However, I am not quite sure if I did the update correctly.

More detail:
------------

- I downloaded all of the kernel *.deb files you provided and tried installing them all using this command:

sudo dpkg -i *.deb

When I did so, all but one of the packages installed properly. I have provided the full text of the error in the attached file 'installation_error.txt'

Despite this error, I rebooted the system to see what would happen.

Upon rebooting, the system provides this output from running 'uname -a':

Linux NUC8CCHK 5.4.0-42-generic #46-Ubuntu SMP Fri Jul 10 00:24:02 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

I make mention only because I am unsure if I did anything incorrectly, so I wanted to make you aware.

That said, now when I access the 'Sound' settings, I now see a 'Line-out Built-in Audio' option under 'Output Device'. Prior to this the only option was a 'Dummy Output'.

I can now successfully test the audio output from within the 'Sound' settings application (and I hear the female voice appropriately on both the right and left channel), and audio output works properly when playing back a YouTube video via Firefox.

In short, things are now working as expected. Despite this, I am unsure if I performed the update properly, and as a result I am unsure if I inadvertently tainted the results in any way.

May I ask what you changed in the test kernel you provided?

May I provide any updated files from my system for your review?

Thank you as always for your help!
