Most PCI sound cards have similar outputs. If you are sure you have a PCI card,
you can use the Shakti Meter to set the volume to 25%. If you are not sure, you can install a sound blaster card. Sound
Blaster cards are made by creative labs, who have standardized their output strengths, so that all creative cards
can be set to the same level - 25%. Creative sound cards are common and often inexpensive to buy second hand.
