noise sound when I make my own compilation

[GoogleCodeExporter]

What steps will reproduce the problem?
1. using the precompiled version everything goes fine.
2. when I make my own compilation, the sound is noise like 50hz transformer.
3. sip registration, calls, hang up, etc. works fine.

What is the expected output? What do you see instead?
the sound is totally destroyed when I make my own compilation.

What version of the product are you using? On what operating system?
webphone last version, red5 9.1, flex sdk 4.6.

Please provide any additional information below.
works perfect with precompiled version, so the problem is when I try to make my 
own compilation. I'm doing something wrong, but I can't find where is my 
problem.....
