ESI Juli@ card issues

[Bill]

Hello

I am using a ESI Juli@ sound card. I want to record audio that is 
streamed through Firefox. I can not listen to the audio stream and 
record at the same time. I can listen to the audio that is being 
recorded through the inputs and record it at the same time but can not 
record audio and listen at the same time from the internet.

This does work in Winblows. Any suggestions?
