MB AD525PV3, Intel Dual-Core Atom, Audio Realtek Chip ALC622 within Intel sound hda board. I have sound when booting with Ubuntu Desktop 64-bits 12.04, but doesn´t have any sound when booting by LTSP.
lts.conf is
[Default]
LOCALDEV = True
SOUND = True
LDM_DIRECTX = True

What can I do to get sound within LTSP?
