[MPlayer-dev-eng] [PATCH] -ao alsa9:hw:0,0 fix

[Wojtek Kaniewski]

hello,

i could be wrong but it seems that with -ao fallback code it's
impossible to specify alsa9 devices like "hw:0,1", because mplayer
treats "1" as secondary ao. i have made two simple patches -- first one
changes all points followed by a number to commas in alsa device name,
so it's possible to use hw:0,1 by "-ao alsa9:hw:0.1". second patch
adds an example to the manpage.

regards,
wojtek
