After some research it's seems to be a common issue on JBL Quantum serie headset. someone already opened a ticket here : https://bugzilla.kernel.org/show_bug.cgi?id=212669 I have the same issue the device node /dev/snd/pcmC0D0c is not created when the kernel module is loaded. The ticket report the issue for a bluetooth headset but I have the same issue with the USB headset.
