YOUR MULTIMEDIA-CAPABLE COMPUTER SEEMS TO RECORD AND PLAY BACK SOUN...

2.

Your multimedia-capable computer seems to record and play back sound and voice at

very low quality. When you try to conduct video conferences over the Internet, your

colleagues cannot understand you, although they have no problems communicating

with one another. You also notice that their voices sound distorted and you hear lots of

pops and hisses.

When you use a different computer in your office, the video conferencing tools work

great. You suspect that there is something wrong with your sound card or the drivers

that interact with it; you want to examine the sound recording and playback devices

installed in your computer. You also want to check driver versions and perform diag-

nostics. How do you do this? Choose the correct answer.

A.

You run Sigverif.exe at a command prompt.

B.

You open the Registry Editor tool (Regedt32.exe) and look for entries that might

be related to audio devices installed in your computer.

C.

You select the Hardware tab in the Sounds And Audio Devices program in Control

Panel.

D.

You open the DirectX Diagnostics tool.
