I didn’t find any SPDIF setting in my sound card settings, but there is a “digital” volume + mute (which actually control the analog output level under stock raspbian…), I tried to mute it but no difference.
In the meantime I figured out why the Alsa Mixer panel in Zynthian GUI (renamed “Audio Levels” in latest update) was empty: you have to add manually what controls it must show in webconf, which I did (I added Analog -which is just on/off as I said earlier-, Digital Left and Digital Right), and they now appear in zynthian GUI… but have no effect.
BTW, while Zynthian boots up I hear two clicks a few seconds apart in the IQaudio output, which tends to show it does something with the board at initialization, but unfortunately this is all I hear.
I also tried hw:3 instead of hw:IQaudIODAC, but no difference either
Also tried a couple of things I found in another forum thread about AudioInjector board where the guy fixed his problem by changing jackd options: -d => -Rd and 256 => 512 but didn’t help either
The hardware works fine when using a standard raspbian SD card instead of Zynthian OS, though the behaviour of the controls is a little surprising, as stated in previous posts:
Trying to think into designers mind as to quite what was originally intended on a card as far as available controls goes is a bit of a pain.
I find I have to clear out the layer and reload it to get an AudioInjector to spring into life on occasion. clearing down the number of LV2 effects in the useful interface made that process considerably easier, as I didn’t have as many audio effects to scroll thro’
Once it’s there it’ seems fine and even survives resets but I do get locked layers when I try to delete them, particularly if they are attached to an audio input.
Hi @pat,
I do not remember if your card is the same as mine: IQaudIO+Pro. Mine works well, at least the headphone output because I’ve not yet tested the RCA and balanced outputs.
Anyway below is a dump of my alsa settings command to get this:

Well that’s a bunch
you can compare yours with mine, or load mine using command:
alsactl --file ~/le51-asound.state restore
assuming that you save the content in a file called le51-asound.state
No, it isn’t exactly the same, I have the DAC+, but they seem quite similar. I dumped my alsa settings and compared them to yours: they are very similar.
Differences are:
Formatting differences: different indentation and different simple quote characters used
You have one more “device” than I do: the first one, called “b1” (HDMI)
Besides this, it seems pretty much all the same… You can check for yourself, mine is attached asound.state (9.9 KB)
After weeks of investigations… I finally figured it out myself: a GPIO conflict between the IQaudio board and the knobs. I had disconnected the knobs for a while in order to rule out such an issue, but the wiring settings in the webconf (which I had found on the forum, but probably from a project using another audio board) were still there and it was apparently enough to interfere with the DAC+. I reset the wiring settings, booted up with the screen disconnected as well to make sure nothing could interfere with the DAC+ which supposedly works fine with Zynthian and I got sound! Then I rebooted with the screen connected and still got some sound, then started adding my wiring settings and it stopped working at some point. So I got the DAC+ GPIO usage info from Raspberry Pi website and figured out my own knob wiring, and I still get some sound after having entered it in the webconf. Last step will be to actually connect the encoders (I had successfully hooked one up in the past, back in the days I had no sound). Hopefully it will still work…
Thanks again @le51 , @riban, @wyleu, @dhrupadiya and all for your help. I’ll be back soon with a couple of questions regarding SFZ support on zynthian
