I consider xmms control interface good, it lets user adjust a lot of
audio aspects. ie the equalization. Not mixer, yes.

In rhythmbox there's the needing of gst support for any of this issues.

In fact after filing this bug I checked the rhythmbox code and noticed
that it uses the gst's volume filter, not some sort of system volume
applet, so the necessity of a mixing interface has decreased.

It was really simple imho to call the gnome-volume-control via the
applet (the panel applet do that) , while calling it and adding the
gst-volume control is harder, AFAIK.

Anyway, a volume bar directly instead of a volume button with a pop-up
bar could improve the UI interface (one less click).

I think the equalization is a streamtuner's job (ie the audio engine).
Rhythmbox can import the eq interface via bonobo, as the volume filter,
letting user modify it (rock, jazz, classic, etc, or advanced settings).

I'm taking a look on gstreamer's internals, if it will be necessary I'll
probably write some code to do equalization.
It's an open issue on gst/rhythmbox lists, so I have to think a little
bit more about it.
