Audio from music player to speaker
 

Hi
I want to know the steps involved in playing an audio file from music player to the speaker.

Music from player to speaker
 

Thanks reed9 the link was informative....

But i want to know the following things.
1. What is the role of music player internally(Is there any conversion of audio data ?).
2. How the audio driver is loaded.
3. In what way the audio streams are passed to the speaker.

can you please help me.

Thanks in Advance.

Well, I'm not a programmer, so I can't give you a good technical explanation. But as I understand it

1. The music player would utilize one of the various multimedia backends to do all the heavy lifting. Example with gstreamer. (Gstreamer is used by Banshee, Totem, and many other media players.) And documentation for the ALSA API.

2. Same as other kernel modules. Usually via udev. More detail here.

3. Not sure how to explain this, but here's the general idea.
