No Sound using FMLE

Hello all, I just install flash media live encoder and after many check up, I have no green square next to the video that indicated that it capted the sound provide by my sound card.

I check with 2 other capture card programm and I hear the sound correctly.

I'm using windows XP (latest update done)

FMLE 3.2

I have a Radeon All-in-wonder 7500

Audio card is a soundmax

Under settings, I choose Line-In and check Active.

Is there a problem that the FMLE cannot take a capture correctly ???

Thanks for the help
