My Hifiberry dac worked immediately. It sounds quite well.
However, It seems to me that the charge pump capacitor on pin 5 of the dac chip is too small.
Can you confirm that it is the cap marked C1 on the board?
Which value is it?
Do you recommend adding a bigger capacitor (e.g. 10 uF) in parallel?
Much kudos for your boards (I've also boght a Digi, and it works fine too).
Thank you for support.
