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.
