Hi,
my soundcard IQaudiO Pi Digi+ missing in I2C card list.
Is it only temporally problem or you do not want to put this soundcard to this list. I don want to buy another brand.
BTW : similar Hifiberry Digi2 pro is there.
Thank you for your answers
It is present in my 3.x installation.
Thank you
Hi, still missing
Where do you miss it? It should be present in Volumio 3.x after a clean install on your Pi. If you miss it in a Raspbian distro you might want to refer to the IQ Audio manual
Hello
I also have the problem of Missing IQAudio Digi+ Card on Volumio 3
I have been trying to fix this problem myself with so far no success.
I have found the dacs.json file in the file system and to my eyes it looks the same as in the Documentation/ other forum post about testing DACs for inclusion. (Small typo/ missng peramiter?)
So from my simple view it looks like it should work but is missing from the I2s dropdown list.
There ae several versions online for the Digi+ manual
Version 30 Includes the Digi+ Later versions do not.
https://wiki.geekworm.com/images/4/42/IQaudIO.pdf
I have followed the instructions, but I have either Bricked the system, or failed to work. Not entirely sure why.
I note that a HifiBerry Digi card also with the wm8804 chipset is also causing problems. Maybe the two are linked?
Thanks
Richard
PS I couldnt find this post searching easily for iqaudio or IQaudio or IQaudiO. Baffled.
There should be 3 IQaudio items in the drop down list. According to the dacs.json file
One of which is the Digi+ which uses a different chipset to the other two. It provides a Toslink (which I use) and Coax output.
I seem to have bricked my system & corrupted my SD card now with my fiddling 
I had a fresh look just before it failed between th system dacs.json the Documentation & V3 beta test help Post. I may have spotted a difference. And then It went wrong…
Fresh head needed!
Fresh system take 4.
Two IQaudio dacs shown, neither of which are for the PI-Digi+
Checked the dacs.json file in the system & documentation

Both of which clearly show the IQaudio Pi-Digi+ as well as the other two. Baffled. And the differences I spotted last night were for the other two DACs, which are showing in the system. More baffled. I was hoping to spot a silly typo etc.
I think I have run out of ability/understanding to progress further. I guess I should fire up a volume 2 install and have a look there next.
Help & suggestions welcome please!
The “iqaudio-digi-wm8804-audio” is missing the “alsacard” setting, that is why it will not be listed.
The alsacard value should be “IQaudIODAC”, identical to the other two.
Like this:
{"id":"iqaudio-digiplus","name":"IQaudIO Pi-Digi+","overlay":"iqaudio-digi-wm8804-audio","alsanum":"2","alsacard":"IQaudIODAC","mixer":"","modules":"","script":"","needsreboot":"yes"},
That won’t help you much 
With V3 all card entries in dacs.json must have an “alsacard” setting.
Thanks gkkpch.
I now have the IQaudio Pi-Digi+ shown in the drop down menu. 
Sadly, it still doesnt work. 
I now get an error
ALSA failed to open “volumio”; no such device.
More to investigate.
Whilst fiddling I noticed that the ST400 DAC Also calls the IQAudio Digi+ Information, so I tried that, and sadly that also fails with the same error (which may be expected but I thought I would try)
And I had just finished writing V2 SD card when I read this. Great timing 
Did you reboot?
Yes.
I made the changes.
Reboot system.
Selected IQaudio Pi Digi+
System Reboots
Tried & failed
Checked my changes & rebooted again
Still fail
Select headphones audio works
Reselect Iqaudio
Reboot
Still fail
Reboot again
Still fail
It has just occurred to me that my system also has a Pico UPS HAT on it. It hasn’t caused problems with V2. But I have not tried to physically remove it yet either, in case there is a conflict of some kind in V 3
I have a similar problem and would love a proper solution.
But I found that selecting R-PI DAC at least seemed to allow ALSA to playback audio - but not sure if this is the best option.
After a interlude with far too much food, I’m back to fiddling.
Happy new year folks!
I have disconnected the UPS board, so I now just have a Pi & IQaudiO Digi+ board.
Sadly the same ALSA No Volumio device fault.

Quite a few errors in the log file. I can spot some of the symptoms, but not sure about much of the causes, as I don’t understand enough. Ill carry on digging though.
Any hints very welcome!
Wheaty
just some thoughts:
open /boot/config.txt and make the following change:
from: dtparam=audio=on
to: #dtparam=audio=on
if the line dtoverlay exist in /boot/config.txt, disable it:
from: dtoverlay=iqaudio-digi-wm8804-audio
to: #dtoverlay=iqaudio-digi-wm8804-audio
open /boot/userconfig.txt
add: dtoverlay=iqaudio-digi-wm8804-audio
Execute the following commands:
sync
sudo reboot
after reboot type the following in the terminal (don’t configure anything in Volumio yet)
aplay -l
Is the soundcard listed?
Yes. I don’t think it has been in the past.

I have tried similar to your suggestions previously, but that was before I modified the dacs.json file & bricked the system again. I want keeping good enough track of the trial and error clearly.
Unfortunalty still having the failed to open alsa no such device error still. 
Sorry to hear. Since I don’t have this hardware I have no other suggestions.
