Okay. I've updated the kernel to 5.7.1 and It has helped me. Audio also works.

@Nickolai, could you also upload dmesg log booting kernel v5.7.1? Your symptoms in 5.4.0-26-generic looks similar to bug 1885573. Both with:

pci 0000:00:1f.5: can't claim BAR 0 [mem 0xfe010000-0xfe010fff]: no compatible bridge window
