Patch works, output is correct (binary compare), but it's slightly
slower on my machine(AMD Athlon(tm) 64 Processor 3700+):

./mplayer -ao pcm:file=/dev/null /tmp/01\ -\ Standing\ in\ the\ Sunset\ Glow.mp3 -benchmark -quiet

w/o patch:
BENCHMARKs: VC:   0.000s VO:   0.000s A:   5.746s Sys:   0.018s =    5.764s

w/ patch:
BENCHMARKs: VC:   0.000s VO:   0.000s A:   5.807s Sys:   0.017s =    5.824s

This is a difference of 1%
