+When disabling the speakers, run rm -rf ~/.config/pulse/ and reboot otherwise the jack will be in the future off or 100% (which is too loud).

 If you see this in Xorg.0.log, it means that simpledrm has not initialized.

+20:29 < Glanzmann> One question though what is difference between chosen.asahi,efi-system-partition=EFI-PARTITION-PARTUUID and chainload=EFI-PARTITION-PARTUUID;m1n1/boot.bin?
+20:30 < jannau> chainload tell's the 1st stage m1n1 from where to load the second stage
+20:31 < jannau> chosen.asahi,efi-system-partition is added to the dt mostly to allow u-boot to boot from the correct ESP
+20:32 < Glanzmann> I see. Thank you for the elaboration.
+20:32 < jannau> chosen.asahi,efi-system-partition is passed from the 1st stage forward to the second stage
+20:33 < Glanzmann> I see, so the first stage informs the second stage about the uuid of the esp partition which is than passed using dt to u-boot which can than select the right esp to select the efi binary.
