Audio filter volnorm seemingly ignored

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Set audio filter such as -af volnorm
2. Play a52 audio

What is the expected output? What do you see instead?

Volume of 5.1 audio such as a52 and dts tends to be too quiet on stereo.
volnorm on mplayer corrects it some. Using gnome-mplayer this setting seems
to be ignored.

What version of the product are you using? On what operating system?

gnome-mplayer SVN on Fedora 10

Please provide any additional information below.

Also, I'm seeing this on verbose output

It looks related since I don't see anything to indicate volnorm being used such 
as
[libaf] Adding filter volnorm 
and plain mplayer doesn't output anything like that.

Where are you setting this extra filter? Did you try adding it to the Extra 
options
in the Mplayer tab in preferences?

The export filter is used for the audio meter and has nothing to do with that.

I tried setting them in ~/.mplayer/config under the right profile (other options
work) and in the extra options gui. Neither work.

Found that I used -af instead of -af-add when adding the export audio filter 
in. So
this was removing the existing af chain. I also found that unless you use the 
-v with
mplayer, you don't see the audio filter chain, unlike the video filters.
