With hardware squeezeboxes this is the case as it is the same volume and signal that eventually becommes the spdiff output , so it's a 24bit scaled signal all hardware squeezeboxes are 24bit all the time with the 8 lower bit's padded to 16 bit sources . Then it can scale with the volume . Software players who knows ? they *should* emulate this . someone knowing the code has to answer this . -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.
