[gst-devel] how to maximize the system sound

[laomie]

Hi,

I'm newbie of gstreamer. I use python gstreamer to play a mp3 file, I
could follow the Python GStreamer Reference Manual and play the file.
But I have a problem, I don't know how to maximize the system
sound. I hope I could use python code to achieve it.

Which gst-plugins-base Element shall I get to solve the problem? Should
I use "alsamixer" element to set the output volume? any idea? any help
will be appreciated.

Thanks for your time,
