Hi,

and thank you again. It was an adventure, but now everything seems to be
good.

Building the linux 6.2.9-custom packages worked after removing the
symbolic link, booting 6.2.9-custom works, HDMI audio works now, but
building the Linux device driver for the RealTek RTL8125 2.5Gigabit
Ethernet controller failed.

   Check old driver and unload it.

I booted the old kernel, while I didn't believe that linux-libc-dev is
the culprit (but I was confused), I replaced it by the original version.
Btw. I didn't found out how to do this by apt only, hence the wget
workaround.

I rebooted and tried to build the module again. When the script unloaded
the old driver this time, I got a notification about disconnecting the
network.

   root at xubu:/usr/src/r8125-9.011.00# ./autorun.sh 

   Check old driver and unload it.
   rmmod r8169
   Build the module and install

   make: *** [Makefile:41: modules] Error 2

   root at xubu:/usr/src/r8125-9.011.00# uname -a

   root at xubu:/usr/src/r8125-9.011.00# modprobe r8169

Building the r8125 module failed again, but I loaded the r8169 driver
and it works for r8125, too. So actually I have Internet access without
the need to build the r8125 module.

FWIW while HDMI audio works, aplay on Xubuntu shows

card 1: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: PCH [HDA Intel PCH], device 7: HDMI 1 [HDMI 1]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: PCH [HDA Intel PCH], device 8: HDMI 2 [HDMI 2]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: PCH [HDA Intel PCH], device 9: HDMI 3 [HDMI 3]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

and on Arch Linux it shows

card 3: PCH [HDA Intel PCH], device 3: HDMI 0 [EV2450]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 3: PCH [HDA Intel PCH], device 7: HDMI 1 [HDMI 1]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 3: PCH [HDA Intel PCH], device 8: HDMI 2 [HDMI 2]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 3: PCH [HDA Intel PCH], device 9: HDMI 3 [HDMI 3]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

The difference is that Xubuntu's "HDMI 0 [HDMI 0]" doesn't provide the
extra information "HDMI 0 [EV2450]" that Arch Linux shows. EV2450 is the
EIZO display's name.

FWIW...

[rocketmouse at archlinux ~]$ uname -r; lsmod | grep r8 
6.2.9-arch1-1
r8125                 270336  0

...the same kernel on Arch, but with the vendor's r8125 driver.
