@Kai-Heng, Thank you very much for your efforts here. I just wanted to provide a quick update...
Short version - I have been able to repeat the positive result using the updated kernel you provide on a fresh install of Ubuntu 20.04.1 (the recent point release). More detail - Since Ubuntu 20.04.1 was just released, I decided to completely erase the system once again and install Ubuntu 20.04.1 from the latest .ISO I performed the installation and then applied all of the software updates (there were not very many, which I understand is to be expected). While in this 'fresh' state, the audio output did not work (which again was expected). I followed the same procedure as I did before (as described in comment #60 --> https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1875199/comments/60) to install the updated kernel you provided in comment #59 --> https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1875199/comments/59 When I did so, as happened before all but one of the packages installed properly. I have provided the full text of the error in the attached file 'installation_log_ver2.txt' Despite this error, I rebooted the system. 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 once again only because I am unsure if I did anything incorrectly, so I wanted to make you aware. That said, I did experience the same positive result in that audio output now works properly. 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 summation, I was able to repeat the positive result using your updated kernel on a fresh install of Ubuntu 20.04.1 and audio output on this system works as expected. Despite this, I wanted to make you aware of the error I received during the installation on the off chance that would be of interest. I would like to thank you again for all of your help throughout the process, it is very much appreciated. Please let me know if I can provide any additional information regarding this issue and I will be happy to do so. ** Attachment added: "Installation_log_ver2.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1875199/+attachment/5399884/+files/Installation_log_ver2.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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
