CamillaDSP 5.1 on Linux Mint - Config Help - device selection overwhelming

I recently converted my Windows based HTPC to Linux Mint. Roon, Plex, netflix etc work great. I lost Dirac live as they don't support Linux and my attempts via Wine and bottles failed so far. I feel lost without it. I know how to make stereo convolution filters in REW and load them in roon, but it is disappointing to have roon sound great, but movies in plex and netflix sounding terrible without DSP frequency response correction filters. I'm told CamillaDSP is the way to go for a low level system-wide convolution filter that corrects all outputs regardless of source.

I managed to get Camilla installed and running as a service on boot as well as the Web UI service. I'm dying trying to create a 5.1 config. In camilla's web UI, I want to select the correct input and output device but the options are overwhelming. My brain is melting! Help! See available input/output below and at the very bottom is my aplay -l response.

Try the ones that include "Denon" in the description.

In the desktop UI for controlling sound I'm using Audio Output: Renoir Radeon High Definition Audio Controller using the profile "Digital Surround 5.1 (HDMI 2) Output"

So, HDMI to AVR

If that does not work, try:

One thing wierd is that aplay -l indicates that the Denon is on HDMI 1/device 7, not HDMI2, which is device 8.

what about input?
 
If that does not work, please post the inputs listed in Mint - the same Sound window as above but with the input tab.

Here is what it will look like when the input is working:

Play music. If it is working you will see the music being received in the left hand panel of the GUI.

Nothing plays now so this broke something. If I select the right in and out, will it play even if nothing is configured on the other tabs yet? For example, pipeline is blank. I haven't made it that far.
 
Here is my Mixers tab for 2 channel. Name yours "to6chan". You need to to set "in" and "out" to 6. Then setup destination 0 to source 0, destination 1 to source 1, ..., destination 5 to source 5.

Here is my Pipeline tab (don't add any filters yet). Yours should indicate 6 in, 6 out. Instead of to2chan you will use to6chan:

OK - I think I got it now.

Capture = hw:CARD=Loopback,DEV=0: Loopback, Loopback PCMDirect hardware device without any conversions
Playback = hdmi:CARD=Generic,DEV=1: HD-Audio Generic, DENON-AVRHDMI Audio Output

Nothing added to any of the other tabs and it works in that I hear music and roon let's me select the previously configured zone without choking.

I'm listening to music as I type this, but the top right corner isn't doing anything. Are those bars supposed to be VU meters for each channel? Also the mute and volume slider do nothing.

Do you mean the top left bars? If so, they should show the input and output volume for each channel. If they are not, I don't know why.
 
Are you sure you need resampling turned on? I don't use it. Here is my devices tab, though my capture and playback devices are different than yours:

So something still isn't right. Nothing changes regardless of what capture device I select and the top left level bars are always dead.

Log file is also giving errors I can't quite figure out.

1749037538636.png
 
OK I ran through every capture device to see what happens. Only the last few options give me the levels in the top left, but none of them are 5.1 just 2.0 regardless of the content I'm playing. I have 5.1 music like Rush - "A Farewell to Kings" or any movies in 5.1.

Here are the log readouts of each of the "working" ones. All three respond with identical logs.

Also playing a 5.1 test file that reads out the channel it's playing on, sounds fine in 5.1. FL, FR, Center, RL, RR but no sub.
