Hello dear ALSA developers.
I have purchased a MC7000 controller in order to control MIXXX on Ubuntu
16.04. According to the Denon specification the controller should have
been class compliant but there is an issue with the Audio interface to
work properly giving following message ...
$ dmesg
...
|[ 74.522831] usb 1-1.3: new high-speed USB device number 6 using xhci_hcd
[ 74.623784] usb 1-1.3: New USB device found, idVendor=15e4,
idProduct=8004

"|||clock source 65 is not valid, cannot use" is repeated uncountable
times then
|I found a discussion here for the MC8000 Audio interface which was not
working and showing the same error message:
https://alsa-user.narkive.com/2tDAO87f/troubleshooting-new-usb-audio-device#post8
The solution was to change sound/usb/clock.c and recompile the kernel.
This is not practical for daily use case so I would like to ask if the
ALSA team could possibly find a permanent fix for ordinary users.
To get my outputs for

you may have a look at the Mixxx Community Forums here(just on page, you
don't need to find and read on multiple pages)

If you need any more information then please let me know.
Thanks a lot for your support on this matter.
Cheers!
