Hi, I've encountered some strange problems with my Xduoo X2. My X2 can detect flac files when I am using Apacer class 4 32GB card. But when I use the Sandisk Ultra class 10 16GB card, my X2 cannot detect any flac files and report that the folder is empty. I've tried to format the Sandisk ultra card with SDformatter. But my X2 still can't detect any flac files. Other music files such as wav and mp3 on Sandisk Ultra can be detected and played.
I have also connect insert the Sandisk SD card into my X2 first and connect it to my PC through the usb cable. Then I would format the Sandisk card by Windows application. But after formating, my Sandisk Ultra card still can't detect any flac files.
Pls help. Thanks!
