[Mplayer-cvslog] CVS: main/libao2 ao_alsa9.c,1.22,1.23

[joy_ping]

Update of /cvsroot/mplayer/main/libao2
In directory mail:/var/tmp.root/cvs-serv792

Modified Files:
	ao_alsa9.c 
Log Message:
changed spdif default from "hw:0,2" to general alias "iec958"
based on a patch by Benedikt Hunz <hunz at hunz.org>
corrected typo in ugly spdif-warning message
added 32/20bit modes for 'high-end'-soundcards
disabled hw-mixer-access for big-endian machines 
(mplayer seems to screw up hw-mixer on LinuxPPC running ALSA
needs more testing, but its safer to disable it for now.)
