DarkIce is a live audio streamer. It records audio from an audio interface (e.g. sound card), encodes it and sends it to a streaming server. This is the official development repository of Darkice.

What steps will reproduce the problem?
1. listen to streaming.urbana.com.uy/urbana
2. darkice 1.0
3. icecast 2.3.2

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?
Darkice 1.0. Centos 6 and centos 5

Please provide any additional information below.

Hi, I have a pc with darkice 1.0 and icecast 2.3.2
My darkice is encoding to a server in USA streaming.urbana.com.uy and to a 
loclhost icecast 2.3.2
We connect to the localhost icecast to listen to the streaming instead of 
connect to the Internet streaming.
We notice that the streaming local and in Internet jumps all the time. But this 
happens randomly, not all the time.

I dont know why LOCAL do that behavior!! the pc only do that.
here goes my darkice conf:

Any idea?
I try changing the ISP (we have 3) and the same. We have enough bandwidth
Thanks

LAME 32bits version 3.98.4 
Here I attach how it sounds when it is bad
The streaming starts ok and then crash doing that.
When is doing that, my winamp player show buffering. How it can buffer in a LAN?

Loglevel in debug can cause this?

GoogleCodeExporter commented 9 years ago 
"Buffered Sink" and "Buffer overrun!" is the problem.  This means there isn't 
enough bandwidth and/or cpu power to encode and upload the stream.

Look at patch r503.  I think it may help with the random jumping... but the 
REAL solution is to get your cpu and/or upload bandwidth fixed.
