Zgemma H7 has an Audio Out, it has a buili-in chip

http://www.3peakic.c...05A-TPF607A.pdf

as you see on the diagram you have to determine two DAC A-out (L, R) tracks going out of the the main chip then tap and amplify the signal, that would be wery difficult, you may destroy your box, easier would be to buy a DA SPDIF to Cinch converter

[mrvica]

didn´t see it, H9 has an A - Out, just take @ims advice

[Piterek79]

Unfortunately, I have different version
