My sound in ichat is not working how can i fix it?

In iChat 4 and upwards the Video and Audio streams are on the same port.
This would make it virtually impossible to block one without blocking the other.
Just to double check
System Preferences > Sound > Input
Ideally this should have the Mic chosen and the volume set to make the blue bar get to at least 1/2 way (3/4s is better). It should not move so far that it bangs into the right hand end.
This will cause the OS software to "Clip" the Audio to prevent feedback - which means no input is made and you will hear nothing.
Next.
iChat > Preferences > Video section.
If there are two Inputs showing in System Preferences he will have a drop down
It should list the same device.
The green bar below the Video pic should also move (Although less than the blue bar did/does)
Headsets
If he is now using a Headset.
Change the iChat Option to anything but the headset mic.
Do the same in System Preferences > Sound > Input.
Now set System Preferences > Sound > Input "First"
And iChat > Microphone Drop Down "Last"
He may need to do this for an Output choice if it appears in iChat and in the System Preferences > Sound > Output.
He needs to be concerned with with getting Sound In to iChat as that is what you hear.
It is easy to think that it is Output as it goes over the internet to the Buddy.
More.
The Video Menu of iChat
In here the Microphone Enabled should be ticked
Selecting this items toggles the tick on or Off (And the Mic On or Off)
I would also check the View Menu
In here make sure the Show Audio Status is ticked.
This will show Audio icons next to the Buddies (Particularly if you deselect Show Video Status)
Show Video should allow Audio but it will not hurt to check.
In fact I would toggle the Microphone Enabled and both Show Statuses to make the App write the info to the .plist
Then try an Audio Only chat
You can do this from the Buddies menu (Or right clicking a Buddy) or by having Show Video Status Off.
Yet more.
I would also open the Connection Doctor from the Video menu at both ends during a chat
This will report the stats.
If his Bitrate is not stable then his audio may be effected.
iChat will try to cope with changes by Buffering the Video which means dropping frames which then means the audio is dropped as it will not be in sync.
You can try Limiting his Bandwidth in the Video Section of the Preferences to 500kbps
This will smooth out large variances when using Extremely fast services that vary.
500kbps is more than enough for a 4 way Video chat as Host but is a useful tool in iChat 5
If his Framerate also varies it will be a sure sign that his Internet speed is varying.
It may pay for you to drop your to 500kbps as well as hs end may be struggling to deal with high data loads from your end.
As a Last resort try both end at 200kbps (Anything below this will not Video)
Change one end at a time and keep an eye on the Connection Doctor to see when the end that has changed has settled. The Buffering will smooth out the change.

Are you signed into your ichat account for starters?

The local Apple Genius Bench was nice to reload iChat and OS for us. But he could not get iChat going for me and my relative. It looks like iChat will have trouble between DSL and Cable but DSL to DSL and Cable to Cable each case is fine. Anyway, after connecting to Apple iChat Test Site
Appleu3test04, my MacBook started to work better with iChat as my relative is able to see and hear us although on my end the incoming picture is not too clear. Then finally Upgrade of New OS seems to make the picture sharper. Thinking back, the original problem came from Modem upgrade to higher speed but I did not use the new DSL telephone filters. Please post this up to help other frustrated iChat users. Anyway, we still like Apple! By Jim on 05/30/2009

• CHECK IF THE SPEAKER HAS ANY PROBLEM
• MAKE SURE THE CONNECTIONS ARE PROPER.
• DELETE YOUR TEMPORARY FILES AND SCAN THE COMPUTER

There's no ichat version for pc until today. but you can chat with mac (ichat) users on pc using AIM from AOL.

- Setup the required ports of the MAC Ichat on your router

Turn off the firewall

Harsh realm. You have to reset the MacBook, or the Netgear? I mean, what happens...you can't even surf to a different site, or the browser freezes, or both browser and iChat? Because I think it might be handy to narrow this down to an iChat or Safari issue.

Then set the problem category to address any unknown problem after googling for iChat/Facebook issues...you know?
