Latest Zynthian with IQAudio DAC+ causes boot-loop

Software
1

Hi,

after searching high and low for a Hifi-berry DAC i came up short (sold out everywhere where i looked) and so i finally got hold of an IQBerry DAC+ and a case that could house it + the rpi 4.

I downloaded and wrote the latest firmware to a 32GB micro-SD and when done booted it all. Everything works fine at this stage.

When trying to customize it all to my particular setup (the IQaudio DAC+) and then rebooting, it gets into this eternal boot-loop and there is of course no way to get out of it.

What am i doing wrong here exactly? Should i do anything differently?

I’m trying to follow the wiki-pages exactly.

Please, could you send the output of this command:

alsa_play -l

The jack config for this device is wrong and must be fixed. You have to replace the “hw:0” by something better, that include the device name.

Thanks

Try replacing hw:0 with hw:IQaudIODAC.
