@gogolink,

If you have tried those kernels and those kernels still failed, there is no need to reinstall those kernels.

Your machine is ab Icelake machine and we hasn't had a chance to enable the sof audio on an icelake machine before. I have no idea why the hdmi codec init fails.

To debug this issue, we need to find the 1st workable kernel for this machine, for example, 5.7.0-rc1 not work, 5.7.0-rc2 work.

So could you please test the mainline kernel to find the 1st workable kernel like:
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.6-rc3/
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.6-rc4/
