I've tried your code and works very well on Flex over a client on windows+firefox connecting to the oflaDemo example, and the red5 server running on a Fedora Core 4. Everything works fine and there's no problem with the files. I'd check the flash player version (9.04) and red5 version (0.6.2).

Asunto: [Red5] Smurf voice when record with Linux
Hi, i've got a problem with my flash recorder.
I've made a recorder with Flex using Red5.
If I record something in Windows, the flv file is recorded and the quality is good, but if I try to record it with Linux (Debian
Sarge) the FLV file is created and recorded, but when I play it the voice is so acute, like a Smurf.
I can't find the problem, i try to record with diferent linux versions and computers, but the problem persists. Somebody have
any idea? Thanks.
