I'm sorry! You are perfectly right! I had commented out all audio codecs
excpet native - mp3 and ac3 - for testing purposes only, because before
mplayer called l3codec.dll for mp3 stream but now it seems that mplayer
uses native mp3lib codec. Well after updating codecs.conf I've got realtime
playback for this movie but mplayer says:
Audio: no sound
Why? This movie has sound stream - I know it.
All other avis (which have mp3 stream) is being played with sound.
May be it would be better -v -v again?

And last observation:
when I tried following options of config:
ao=sdl			# To specify default audio driver (see -ao help for
			# list)
ao = sdl:esd		# use SDL audio driver by default
	    		# use "ao = sdl:esd" to use SDL's ESD driver

I've got very distorted sound on output from my SB16.
(basses were very weak but highest frequencies were top loud
and distorted).
Is it a bug or is it a feature?

After commenting out 'ao = sdl:esd' sound is crystal clear.
