Ok, I think I'm getting crazy. So I've even installed 2 ferrites on both ends of the cable going into the STL.
Same results.
I'm posting screenshots of my analyzer in case you see something I can't see. RDS is enabled on ST.
And here's a screenshot with RDS set to off. There is still something on 57khz.
When I lower my sound out to 0.200 (normally at 0.700) there is still something on 57. The 19k pilot of course is lowered now.
The strange thing happens when I lower the input too much (ST shows activity on input at the first green level)
Update. Phase diff. appears at -52 deg again, after 2 songs played.
I'm sharing my preset as well.
