I found out that I had to short two jumpers on the f panel. Jumper 5-6 and 9-10. And now I get sound on the lineout and I get to use the Vinyl Deck from VIA which gives me plenty of adjustments and more.
That was what I was afraid of. This board is inside a C64 and is extremely hard to get to now. Why the heck was the board set to front panel only from the start?! Bloody stupid!
