POWERtools Infiniti Mac clone problem

A reader reports: "If you are the owner of POWERtools Infiniti computer and are having problems with the audio out on the CD-drive, then there is a good possibility that you got a 'Demo' drive. I recently upgraded mine, but instead of shipping a replacement 16x drive they sent me a 12x one. The model number for the 16x is XM-6002B. If you have a number that is XM-5702B, then you have a Toshiba 12x drive. POWERtools says it is aware of this problem and taking steps to correct it."
