[HD2 Android NAND Development] Elibl:
low volume/no volume(DataOnExt):

i had no sound at all after changing my sdcard (verbatim class 10) into a new one (sandisk ultra mobile uhs-1) what by the way brought an significant increase of over all smoothness (despite the verbatim is already a pretty good one in normal file transfer)

after restoring all my files i had no volume at all so here some logcats for your info tytung:

try to play mp3 with apollo:
