16. Using more than one Sound Card
It is possible to use more than one sound card in your computer. A user may not be satisfied with a sound
card that is built onto the motherboard for example, so she might install a second sound card. However, after
installing a second card, resource issues related to sharing can arise. As always, be sure to check for IRQ
conflicts i.e. sharing with firewire and/or USB etc… It is best to simply disable (or remove) the unused sound
card or sound section of the motherboard. See earlier section under IRQ Sharing and Disabling.
17. Power Related Issues Regarding Laptops
Because laptops are portable devices, they are able to operate on both AC and battery power. In some cases,
when a laptop is running on AC power (not battery power), grounding issues can arise. If you are experiencing
noise in your audio – try switching to battery power to see if your AC power has a problem. In addition, if your
laptop is running on two batteries, try running on one battery to see if one of the batteries has a problem.
18. Laptops Hard Drives
Some older laptop drives (4200RPM) are not able to keep up with the demands of modern digital recording.
Be sure your laptop is running on a 5400RPM drive with 8MB buffer or higher. Most new laptop drives already
fall within these specifications.
19. Device Driver Updates
It is not unusual for product to be shipped with software and drivers that have become outdated, as it would
depend on when the device was packaged and put into circulation. Be sure your device drivers are up to date
by visiting our web site from time to time.
20. FireWire Performance and Windows XP Service Pack 2
After you update your computer to Microsoft Windows XP
Service Pack 2 (SP2), the performance of your 1394a (or
1394b) FireWire devices may be greatly decreased. This
problem occurs if you connect a 1394a (or 1394b)
FireWire device to a 1394b port. This problem occurs
because Windows XP SP2 changes 1394b ports to S100
speed when you upgrade. Having said this - SP2 is still a
very important update. Also see:
