probably driver problem

lame's libmp3? what the hell. i remember something like mp3 decoder in lame,
but it isn't separated from liblame, and is not supported by mplayer for
decoding. mplayer's mp3lib is based on mpg123, and is float (sse/3dnow)
based. if you need integer, try libmad or libavcodec's mp3 decoder, afaik
both int based (-ac help).

it's bad, very bad! as GETOSPACE is used to sync video to audio in mplayer.
without it playback gets jerky (people with soundcard with buggy drivers
already know this) - on linux the workaround is using SDL over OSS.

no, but check any ao_* source, and read DOCS/tech/tech-eng.txt libao2 section
