* Tried your Hdmi.conf. It turns out that the system did not even boot. It did not bring me to the usual Ubuntu login GUI screen. I got stuck at a black screen with the message
[ 14.652221] sof-audio-pci 0000:00:1f.3: error: no reply expected, received 0x0 * So I forced reboot and selected 5.4.0-26-generic instead, hoping that it might boot up so I don't need to use some recovery USB. Indeed, it did boot up. * As I understand it, dmesg.0 is the dmesg from the previous session. So I am attaching it here. I hope this is the right dmesg log that corresponds to the session that gave me the sof-audio-pci error above.
