@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! ** Attachment added: "installation_error.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1875199/+attachment/5397750/+files/installation_error.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1875199 Title: [NUC8CCHK][HDA-Intel - HDA Intel PCH, playback] No sound at all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1875199/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
