Jesper,

My guess is that you're capturing analog TV and the capture card's audio 
output is piped into the computer's sound card. The most common mistake 
with this setup is setting the mixer levels for that input on your 
soundcard (e.g., Line In) to anything more than 0%, so once the capture 
card has been opened, the sound stays on. I know this is 
misleading/counterintuitive (I've made the same mistake). What you 
should do is set the mixer level for that input to 0, and instead find a 
switch in your mixer program called "Line In capture" (or whatever input 
it is), enable it, and also find and set the level of the audio 
recording Capture.


Cheers,
Jesse
