If you search in a song, the back speakers stop playing, if I search again they start playing again. This happens everytime, and it doesn't matter if you use the mouse or the keyboard. I'm using 6.1 with 24-bit fixed-point. I thought I read about someone who had the same errors, but that was with the previous RC (I had it too) and it doesn't seemed to be fixed in the newest so I'll make another bugreport.
