fixed spdif
spdif device depends now on the given subdevice was hardcoded to hw:0,2 before fixed opt-parsing for hw:x,y like opts seperated initialization of spdif from common init as it was probably intended before git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@6703 b3059339-0415-0410-9bf9-f77b7e298cf2
