I'm very tempted by this dac for a multi-channel setup. Has anyone had experience with it? I'm particularly interested in having access to each channels volume control. I'm assuming that I can do this via an arduino but I can't find any info on how to set this up. Any ideas?
Alternatively, the Topping DM7 looks like a good idea = who can help me hack it so I can have access to the individual volume channels? There is a reward waiting....

Just my 2 cents but I don't think choosing the DIYINHK DAC over a commercial offering makes sense. In addition to the Topping look at the MOTU Ultralite Mk5 and the Okto dac8 pro. If you do go the DIYINHK route I would go with their ES9016 offering over the ES9038.
What do you want to do with the individual channel volumes? Adjust them once so the channels are at different levels? Or dynamically use the volume control of each channel?

Michael, thanks very much for those threads - I had not seen either. Very informative.
And you've already helped me so much in the Rpi4 Camilladsp thread.

My project is to make my Ultimate Remote Control. I hate push button remotes that don't respond in a human way. So I'm making a 'coffee table remote', cnc'd from aluminium and beautiful to hold, that I hope will be the final answer. This will use a master slider pot and 2 more for ambience and bass adjustment. The receiver will use large neopixel rings to show the levels - I have never liked the rather inhuman -xdb display format.
I listen to a lot of eclectic classical music and find that the recorded sub bass/ bass levels vary enormously. it's really useful to be able to cut/boost them recording by recording. (I have a huge 5m bass horn in the ceiling and a bus driving past a in solo violin recording can really freak you out!)
Also, and I don't care if this upsets the purists, I use rear ambience (reverb) channels for a hugely enhanced listening experience.
http://www.goodsoundclub.com/Forums/ShowPost.aspx?PageIndex=4&postID=26262 . This is a great thread - and there is no way back once you've gone down this route. The trick is to raise the ambience level slowly for each recording, until you can hear it, then back off a bit. This is very easy with a slider remote, and nasty and fiddly with push buttons.
My system uses Audiolense fir filters with CamillaDSP/rpi4 to an 8 channel DAC. 4 channels control my 2 way horn speakers and the other 4 are for the extra subs and ambience speakers.

As I see it the options are -
1. Make a 8 channel attenuator.
2. Find a 8 channel DAC that can use digital attenuation per channel and can be controlled by my remote's arduino/esp32
3. Find a clever person to write a widget so CamillaDSP can talk to my remote and control everything.
Each has it's advantages.
1. Topping DM7/Motu M5/Octodac can be used. But perhaps a 8 channels of balanced relay attenuation boards is a lot of mess for not much gain?
2. Would be good - But the learning curve for programming dacs seems steep. I'm half hoping that aktoDAC can come up with something affordable...
3, Seems the neatest solution. But requires CamillaDSP/Rpi4 expertise that I don't have, and might be impossible anyway.
your thoughts would be very welcome!

Option 3 sounds the easiest to me as you are already using CamillaDSP.
Check out the threads below discussing using a bluetooth knob to manipulate the CamillaDSP bass/treble tone controls. Conceptually I think what you want to do is very similar except instead of changing the gain of shelving filter you would change the gain of a gain filter.

Great, it looks like it's possible!
Although, I'm nervous about the learning curve of getting the Camilladsp/rpi4 to talk to my remote receiver.
At the moment I'm using ESP32 with ESP now for the remote transmitter and receiver. Is it a question of making a serial connection to the RPI GPIO pins and modifying your FLIRC script to read the values?

Yes, I think it should be as simple as that. I am sure if you contact MarcosCh on ASR he will share his python script that he used for the tone control, that might give you some insight on what needs to be done from a CamillaDSP side.
