PLAYING AND RECORDING
WHEN PLAYING FILES FROM MY SCSI DRIVE, WHY DOES THE SOUND HAVE A
WARBLING EFFECT?
When playing files from a SCSI drive connected to a SCSI controller that
utilizes a DMA channel (such as most Adaptec controllers), you may
experience a warbling effect in the sound playback. This can occur if your
sound card uses DMA and the DMA channel is set to a higher number than
your SCSI controller.
To fix this problem, set the DMA channel used by your sound card to a lower
number than that used by your SCSI controller. For example, if your SCSI
controller is set to DMA channel 5 and your sound card is set to DMA channel
7, try reconfiguring them so the sound card uses DMA channel 5 and your SCSI
controller uses DMA channel 7.
WHEN I START SOUND FORGE XP MY PLAY AND/OR RECORD BUTTONS/OPTIONS ARE
