just turn off your computer and monitor........yes you have too!!
Turn the computer around a bit so you can see the back panel.  look for a narrow, metal plate with several small, open jacks (holes) in it. This is your sound card. You may have 2, 3 or 4 jacks there.

Common ones are line in ->)), line out <-((, and the mic jack. We are most interested in the line out and mic jacks. newer comps will have green and pink connections, easier!

if you have just a stand mic..... you will connect the plug into  the mic slot.....(item 2)

if you have a headset mic..... you will plug the mic into  the mic slot  ( item 2) and the headphone plug into your speaker output  jack (item 1)

now just restart your comp......and now run the audio wizard ......then return to yahoo chat :)

hear an echo in your headset?  This is normally caused by the mic not being muted in the playback volume controls. Go to

• START,
• PROGRAMS,
• ACCESSORIES,
• ENTERTAINMENT or MULTIMEDIA (if you have Windows 95),
• open Volume Controls
• Look for Microphone balance and volume slider (if you do not see Microphone, within the volume controls go to Options then Properties. At the bottom of the window, scroll down the list, then check the box next to the Microphone option. Click OK.
  (Playback section)
• Make sure Mute is checked below the mic or make sure there is no check in the box labeled Select below the mic.
• some people may need to have the LINE IN BALANCE box muted for their mic to work

• Go to START,
• PROGRAMS,
• ACCESSORIES,
• MULTIMEDIA, and open
• SOUND RECORDER to test mic....
• make  a short recording and play it back.

a few other things to check if you still have probs..... make sure you do not have netsonic or real player in tool tray (icon down by clock ) when you try chat.

if you have realplayer you need to disable it before you ever get near yahoo chat. i suggest making sure it is not in start up at all. resource hog. and not compatible with yahoo voice chat.

voice in use by another application? check here !!

and most can NOT listen to napster or cd's and voice chat as well.... one audio application only....and you can always refer to the official voice help pages

if (for example) you have a headset and speakers..... you may have the option of plugging the headset into the  jack on front of one of the speakers.....and the speakers then  is plugged in  output 

if you have a stand mic, and hear whining noises or squeals, try moving mic farther away from speakers

breaking up? choppy chat? This may be due to a slow connection or Internet traffic. A faster modem, DSL or T1 connection will help solve this problem. or using a client.... (not java based) they seem to be able  to support voice better for some chatters. or it could just be yahoo.
