I have a PIFI Digi DAC+ HIFI DAC Audio Card and want to use GPIO Buttons https://volumio.org/forum/gpio-buttons-control-volumio2-with-buttons-t4437.html. The auto card however covers all the pins on the Raspberry PI. Am I able to solder the buttons onto the matching positions on the audio card or will this break something?

Hi,
I have Kuman PIFI Digital DAC+ HIFI that looks similars to yours
kumantech.com/kuman-pifi-dig … p0051.html
GPIO they used on this card are : 3,4,5,12,35,37,40 and maybe yours are the same so you can use others for buttons.
And you don’t need to solder if you don’t like; you can use
-
extension card like this one ( but not this because they are are defective from manufacturing - have a missing line ; they send one more to me and also with the missing line ) : amazon.fr/Quimat-dextension … 7extension
-
a cable to connect sound card: amazon.de/gp/product/B00QE3 … UTF8&psc=1
-
cables to connect buttons : amazon.fr/Ganvol-Flexible-B … ires&psc=1
Hope this can help you!
Thanks so much, this is just what I am looking for. Do you have another link for the sound card cable as the one you gave does not appear to resolve?
Don’t know much about the cable , just search on local market web sites for a RPi3 ribbon cable 40pins or this one:
amazon.com/GPIO-Ribbon-Cabl … bbon+cable
As I told you, don’t use the extension card as I do , I think this one is better:
amazon.de/MakerHawk-Raspber … cable&th=1
Are you kidding me…they are using the old 40 pin ATA IDE ribbon cables used in PC’s 20 years ago 
I didn’t even think about it until this post, but I have some old ribbons kicking around, perfect for an application I have in mind. Thanks for triggering the ol’ brain to fire off some synaptic activity. 
Yes , they are . But old 40 pin ATA IDE ribbon cables sometimes have one closed hole.
Hi,
Regarding the “closed pin” - you can easily “unclose” it by pulling out a little plastic part that is only plugged in there in most cases. Use a needle or a micro screw driver for that.
In general please keep in mind - if you are using I2S and I2C signals over a relatively long cable like this, these signals may get instable.
