SD card

Sorry for broken english.

I used Rpi B type made in the Uk. dac is audioquest Dragonfly

And the SD card,Sandisk 16GB 30MB/s Ultra.

when play the music,there’s so many noise like "chi chi chi " every minutes.

But I change the SD card,Sandisk 4GB with blue Skin. the noise is less than 16GB SD card.
