I wonder if you tried another one of the four channels if it would make a difference - probably not.
Yes, I already tried that before without any result.

But I tried something else this morning and it might be I'm on to something.

I took a regular stereo cable and I plugged all 4 the phono to RCA plugs at both ends.
So in the line outs 2 cables and in the line ins 2 cables. And again it worked and got to 9db fs wich is enough. I think the break out box or soundcard only reads the signal if it comes from 2 cables. This is only so with the line ins though. So I might have some good news and bad news.

the good news is that we may have solved the problem this time. the bad news is that I may need to find a plug that has a phono in at both ends and a cable that devides a mono signel into 2 cables. wich means only one cable at the one end and devides into 2 cables at the other end. So even though the signal from the spl meter is only mono I might still have to devide over 2 cables. I think the soundcard only reads a signal if it comes from to cables.

The line out shouldn't be a problem with only one cable that goes out to the BFD.

very strange though.

any sugestions to make it easier that have to buy a new cable and phono to phono plug?(the cable from my spl meter to my soundcard is 10 meters so I can't replace that cable or I have to move my whole pc equipment to my room)
