Dvd drive - no sound

When copying discs from my Lite-on 167T to HP dvd writer 640b it copies the movie ok but there is no sound. Everything else about the drive is fine, it operates correctly, only disc to disc transfer is this problem. I have the RW drive jumper on Master and the Lite-on DVD-ROM jumper on slave and I have just recently installed the Lite-on drive

Thanks
