Hello! My question its pretty simple. I bought a bluetooth speakers that I connected to my desktop computer (with windows xp sp3) using a bluetooth usb pendrive. I can hear perfectly the audio generated by the computer , ut the problem comes when I want to use the Line-in from my soundcard and sending to the bluetooth speakers, the audio simply does not work. I tried to change the settings in control panel > sound

Im pretty sure that the problem lies in the connection that my soundcard has, the line-in should only go to the line out of the card, and only the audio generated in the computer can go trough bluetooth. Can anyone tell me if there is a way to cheat the computer so it recognizes the line-in audio as computer-generated audio and sending by bluetooth? Maybe there is a software but I sincerely dont know, please help!!
