Newer Kernels will surely also provide native audio support for this controller.

-===== Appendix: Linux Kernel ===== 
- 
-Knowing this is a WIKI site for the controller but to get it working with Linux I wanna provide you some information here... ​ 
- 
-1) Good News: there is a patch available for the 5.5.2 and 5.5.3 Kernel. It is possibly also working with older Kernels but I only tried the 2 mentioned. I can state though that for 5.4.18 it failed to patch. 
- 
-2) Better news: The patch goes upstream so newer Kernels will support the Denon devices out-of-the-box in the future. As soon it is implemented I gonna give the Kernel version number here. 
- 
-3) How to apply the patch using Ubuntu based distributions like all flavours of Ubuntu, Mint, KDE Neon etc.: 
-  * create a folder named "​Kernel"​ in your home directory. 
-  * download the zipped [[https://​www.mixxx.org/​forums/​download/​file.php?​id=2816|patch]] and extract the file into the "​Kernel"​ directory. 
-  * download the [[https://​www.kernel.org/​|Kernel source]] into the "​Kernel"​ folder and unpack the file as user. A new sub-folder, e.g. "​linux-5.x.x"​ is generated. 
-  * open a terminal and move into the new generated "​~/​Kernel/​linux-5.x.x"​ folder 
-  * apply the patch using following command 
-    * patch -p1 < ../​0001-ALSA-usb-audio-Add-clock-validity-quirk.patch ​ 
-  * now copy the existing running kernel configuration to the new one with 
-    * cp /​boot/​config-`uname -r` .config ​ 
-  * and apply the developers recommendation to all new changes for the newer kernel with 
-    * yes ""​ | make oldconfig ​ 
-  * now build the kernel with  
-    * make -j $(nproc) 
-  * and install 
-    * sudo make modules_install 
-    * sudo make install 
-  * reboot your machine and select the new kernel in Grub boot menu.  
-  * you should have got working sound out of your Denon now! 
-  * When the new kernel is installed you are save to remove the complete ~/Kernel directory. 
-  * to remove all installed kernel items just do: 
-    * locate -b -e *5.x.x* | xargs -p sudo rm -r 
-      * remark: *5.x.x* indicates the kernel version to delete (change to your version) 
-      * **important:​** the command will list all items to be deleted and ask for confirmation - **check before confirming**. There should only be items in /boot , /​lib/​modules and /​var/​lib/​initramfs-tools/​. Adjust the "​locate"​ search string accordingly if needed. 
-    * sudo update-grub 
- 
-Disclaimer: The method described here is tested using Ubuntu 16.04 and mentioned as guidance only. You are solely responsible for your system and if you are unsure then consult your Distro documentation. If you are very uncertain about compiling or deleting the kernel then better just wait until the patch is available upstream. PS: You can always contact me for help.
