SBS, slimproto, and ALSA all support 192/24. The new VortexBox player supports 192/24 and it has been working very well with SBS. -- agillis rip, tag, get cover artÂ… All you do is insert the CD! http://vortexbox.org agillis Lead Developer VortexBox ------------------------------------------------------------------------ agillis's Profile: http://forums.slimdevices.com/member.php?userid=21140 View this thread: http://forums.slimdevices.com/showthread.php?t=74688
