After installation mavericks i use WOODOO HDA for sound working. But, when i install kext for apple battery manager, i must copy and replace DSDT file to EXTRA folder. After replace this DSDT file, woodoo hda ist not working, and i was deleted this. sound working perfectly. On midi app i was add new device and set default for output, but sound not working after them.
PS when sound working, subwofer not working, but any signal is on a subwofer. I dont no whats the problem.
