key named "value" for mixer controls is type of Array
An example control from my mixer looks like
{
"numid": 9,
"name": "Line 03 (Headphones 1 L) Playback Volume",
"iface": "MIXER",
"actif": true,
"value": [
127
],
"ctrl": {
"type": "INTEGER",
"count": 1,
"min": 0,
"max": 127,
"step": 1
},
"acl": {
"read": true,
"write": true,
"inact": false,
"volat": false,
"lock": false
},
"tlv": {
"dbminmax": {
"min": "-127.00dB",
"max": "0.00dB"
}
}
}
It seems odd that the numerical value of the control is an Array rather than an Integer. Are there single mixer controls that have more than one value?
Issue with scarlet 18i20 2nd gen

I just got a scarlet 18i20 2nd GEN and i'm trying to make AlsaJsonGateway working with. I've a working installation with a 1st gen 18i8, and i'm trying to use the same config for the new scarlett but got this error.

I also attached a screenhot of the mixer view.
I also have to say qasmixer doesn't show me mixer's capabilities
I'd really appreciate informations or workaround to help me to debug this :)

Probably this is the important part:

Would be happy if you could lead me; if this is something with a code; or with my system.
I've checked deps and I think they are installed OK.
Thanks.
Fix build when using libmicrohttpd 0.9.75
Building on ubuntu 22.04 requires a trivial fix due to some changes in the libmicrohttpd version available for installation through apt-get.

Installation problems
Hello. I am having a number of issues attempting to install this and getting it to work properly with Alsa Json Mixer.
I am using Fedora 28. All dependencies install fine and compiles complete without error. Only problems with installing and actually getting it to work. I think a simple step by step, copy commands from readme file would be more helpful than the video.
- The instructions say export AJW_DIR=$HOME/AJW. However, should this be /opt/ajg-daemon instead?
- sudo make install does not create /opt/ajg-daemon directory. Even if I manually create it, nothing is installed there. Instead, there are files installed into /usr/local/var/www/fakemod. I cannot see that any other files are installed anywhere else.
Please provide some guidance, I am very interested in the excellent work you have done and using my Scarlett 6i6!
make a release for xenial in PPA
The PPA isn't usable for newer systems 16.04 or 16.10 because there's been no release published. Please publish one so the PPA is usable. Thanks

Some routing not updated when opening a preset
First off, thanks for creating this software! I'm not sure if the problem I'm having is with my setup or if it's a bug.
I'm having an issue where after I start up a session and choose a preset in the HTML5 interface, I have to toggle some of the routing selections to something else and then back in order to make it work. For example, If Capture 1 is set to "Analog 1" in the preset, and I try to record from Capture 1, nothing will come through until I toggle Capture 1 to "Off" (or another selection) and then back to "Analog 1". This happens with some volume controls, input selections, capture selections, master playback route selections, and potentially other controls.
The interface I'm using is the 18i8. My machine is running Ubuntu Studio 14.10 with all up-to-date software. I installed the 4.0 realtime linux kernel to get the improved support for the interface. I'm happy to provide any other information that might.

MHD_start_daemon error when trying to install/build
Hi there, I'm on a fresh install of Pop OS 22.04 and I can't seem to run the final command for building in the readme. I've got an 18i20 that is detected by the OS and shows that audio is outputting through the settings and in easyeffects, but there's no audio coming through any of the outputs on the device (I've tried them all)
alsamixer shows that it recognizes the device and all its IO, and correctly shows volumes being changed when I turn the knobs, but again, no actual audio coming through. Ive got a 2i2 that works perfectly fine out of the box so I know its not the hardware connected to the devices. The following is the message I receive when trying to build. Any help is appreciated. thx.
