I applied the patch and when connecting the Denon MC7000 the attached is
what dmesg shows...
Hope you can find something useful in there.
Please let me know, if I can be of any more help.
Thanks a lot.

Thank you for taking care of this...
I have tried with the latest Kernel 5.4.11 in Ubuntu 16.04 and
$ dmesg
still shows
"clock source 65 is not valid, cannot use"
My current running stable system is
$ uname -a
$ Linux tobias-V130 4.15.0-23-generic #25~16.04.1 SMP Fri Dec 20
20:16:19 CET 2019 x86_64 x86_64 x86_64 GNU/Linux
in where I applied the chane described in here:
https://alsa-user.narkive.com/2tDAO87f/troubleshooting-new-usb-audio-device#post11
Just for my understanding what you now need me to do...
deleting the line in /sound/usb/clock.c that states "return -ENXIO;"
and compile the kernel again.
Yes, and with that, the error message still remains. That's not
wrong. The question is to identify who calls this function.
So...
Clemes mentioned in his last post to add logging but I have no idea
what he means by that. Can you briefly guide me what I would need to
do?
... try the patch below instead. This should work for the recent
kernels. It'll give Oops-like kernel WARNING with stack traces, so
show them. There can be multiple occurrences.
