[Fix 11.8.4] Audio fade in bug 11.8.3.4

[allcomp]

Hello Mike

If you set your starting point from the middle of a song, the "fade in" timing is not working as it should. It works if you set your starting point from the start of the song.

I´ve downloaded the 11.8.3.4 and no problems with fades in that version.

Fix ready for 11.8.4.
