problem

[Flinki]

Hello!
First I wanna say sorry for the mistakes i will make!
but I'm from Germany und i can't speak english very well.
But i hope you can help me and you will understand me!

My problem:

I have a internet radio and i'm sending the songs with shoutcast!
I'm sending with 48 kbps (good audio quality) and all is okay.
But when i change from "Winamp Recommended" to "Soundcard Input" it often stops to send and it must reconnect.
but AFTER the reconnect i'm sending with 24 kbps (bad audio quality).
Why is the sound quality changing after the reconnect?
And why does shoutcast reconnect when i change from "Winamp Recommended" to "Soundcard input"?
Could somebody help me?
Sorry 4 the mistakes!
