I attempted the process you describe, however I cannot find any kernel version which allows for the audio output to work within Ubuntu 20.04.
To reiterate, when testing the system with Linux Mint 19.3 with kernel version 5.3.0-51 #44-18.04.2-Ubuntu sound works properly. I used these instructions --> https://wiki.ubuntu.com/Kernel/MainlineBuilds to install these kernel versions from --> http://kernel.ubuntu.com/~kernel-ppa/mainline/ : 4.20.17 5.0.21 5.1.21 5.2.21 5.3 5.3.1 5.3.2 5.3.2 5.3.4 5.3.5 5.3.6 5.3.7 5.3.8 5.3.9 5.3.18 5.4.45 5.5.19 5.6.17 5.7 5.7.1 None of these kernel versions allowed for the audio output device within the system to be detected from within Ubuntu 20.04. Only the 'dummy' audio output shows within settings. The system is dual-booting Ubuntu 20.04 and Linux Mint 19.3. When I reboot into Linux Mint 19.3, the audio output is recognized and works properly. Please let me know if I can provide more information from either the Ubuntu installation or Linux Mint installation to help troubleshoot the problem and I will be happy to do so. I can also erase the boot drive and reinstall Windows 10 if that helps.
