Distortation for 2 to 4 seconds at beginning of songs

[Chuckster1936]

I am trying to import an audio CD into Hoster and I get distortion at the beginning of most of the songs. I made a copy of the CD on another computer and the same problem occurred when I tried to import it on this computer. When I try to play it using Microstudio, it plays fine in Audio playback, but distorted in Karaoke playback. I have 12,000 songs on my computer and about 1,000 are audio with no problem in the past. What am I doing wrong?
