Hi Michael, as for the Main 1-2 issue, a factory reset seems to have done the trick. I will check later whether the other issue is resolved, too.
Michael, do you know if its possible to have the volume "reset" to -40 whenever there is a configuration change?

Why not just make it conditional in that section, and add a config variable or two near the start where it's clear people need to edit things?I'm debating if I want to make this default behavior. It probably makes sense where you are using config switching to change inputs but would make less sense where you are using config switching to implement different DSP profiles. I think I'll add it to flirc.py but have it commented out.
Good idea, I clearly don’t think like a programmer.

Michael, just noticed https://github.com/HEnquist/camillagui-backend/releases has v1.0.0-rc3 updated frontend with bugfixes and improved plotting.
Thanks for the tutorial. I wonder how effective this would be when using a stereo DAC instead of multichannel, as that would eliminate the need to buy a new DAC unit.
Is there a measurable advantage to processing DSP before outputting separate individual subwoofer and stereo channels via a multichannel DAC unit like the M4 compared to processing DSP, outputting the resulting stereo channels via a stereo DAC then adjusting the crossover on the amplifier?
So
Pi4/CamillaDSP -> multichannel DAC -> individual channel outputs (stereo amplifier -> passive speakers, subwoofer RCA -> active subwoofers)
vs
Pi4/CamillaDSP -> stereo DAC -> multichannel amplifier with bass crossover -> active subwoofers & passive speakers
Thanks, multichannel definitely sounds like the way to go then. My amp has a configurable crossover for high pass filter etc but doesn't have phase or anything else unless you disable pure direct, in which case it's noisy.A stereo DAC will work, you just lose some of the primary benefits especially if you are using subwoofer.
With a multichannel DAC you can apply individual correction to both the subwoofer and the main speakers, for example high passing the mains or applying a Linkwitz transform to the sub. If you have an amplifier with x-over capability you may be able to high pass your mains but I bet it is a lot less flexible than CamillaDSP in terms of frequency / slope / Q.

Do you know if there is anything that compares to the MOTU M4 in SINAD and price? I really want a coax or optical digital input, which the M4 lacks, and with the M8 being about twice the price of the M4 I may as well buy a MiniDSP Flex at around the same price.

Is anyone using librespot (Spotify) on this setup? I have a problem where the volume is super coarse when I connecting from iPhone. I start at 25% and that is already loud a couple of clicks down and is muted, a couple of clicks up and its very loud, and the volume bar on iPhone is not even half way.
Here is the command looks like to start the library:
Code:/opt/librespot/librespot \ --name Living Room \ --backend alsa \ --bitrate 320 \ --device plughw:0 \ --mixer softvol \ --volume-ctrl linear \ --initial-volume 25 \ --onevent /opt/librespot/onevent
In the other hand, controlling the volume via Roon works as expected.
I have not but I am glad to hear that someone is using librespot as a few folks have asked me about it.
Are you saying that the CamillaDSP volume control is too coarse? Or are you using a volume control in librespot?
Michael
This does not seem to be a CamillaDSP specific issue, as it seems to be working properly with Roon, which I have configured to do volume control in software (i.e. I am not using the CamillaDSP volume controls).
When using Spotify on my phone (or Desktop app) and connecting to the Pi running CamillaDSP and librespot, that when the Spotify volume controls seem to be incorrect. I assume there is something amiss with librespot configurations.
