it seems that you are using oss. Did you configure that in your profile
or in /etc/mplayer.

are you running pulseaudio?

Does the delay occur if you use some other audio module, like the
pulseaudio module or alsa?

no, i have done no manual configuration of mplayer (just 'sudo apt-get
install mplayer')

pgrep shows that it is running

i tried:

  $ mplayer -ao pulse brownian.ogg

and there was no lag in changing the volume (i.e. it worked correctly)

when i tried to change volume with alsa i get:

     [AO_ALSA] Unable to find simple control 'PCM',0.

with the normal ubuntu package? for me, it tries pulseaudio first.

excellent, so there is probably no problem in mplayer.

but does it produce any sound? or are you 'just' not able to change the
volume?

in any case, please attach:

 a) the full mplayer output, including the full command line
 b) the contents of /etc/mplayer/mplayer.conf
 c) the contents of ~/.mplayer/config

interesting. How can you please also attach the following outputs:

mplayer -v -ao alsa brownian.ogg
mplayer -v -ao pulse brownian.ogg
mplayer -v -ao oss brownian.ogg
mplayer -v brownian.ogg

Ideally in seperate *attached* files so that we can "diff" them.

My current suspicion is that mplayer behaves different on amd64, but I
don't know yet why.
