@Kai-Heng, I tested the behavior of Linux Mint 20 via a Live USB stick and the audio output did NOT work. The only audio device detected is a 'Dummy Output' device. This behavior matches that of Ubuntu 20.04.
To put that another way, there appears to have been a regression in behavior between Linux Mint 19.3 and Linux Mint 20. Audio does work with Linux Mint 19.3. Audio does not work in Linux Mint 20. @Hui, You ask, "...if you plug sth in the line-out port, what will happen?" I am afraid I am not quite sure what you are asking me to do. Could you please provide some additional detail? Just a reminder, at every point during my testing standard analog speakers have been powered on and connected to the host system's 3.5mm audio output jack. To put that another way, I am testing with a 'real' hardware setup. Please let me know if I can provide any additional information, and thank you both as always for the help! -- 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
