bad mic/speaker feedback on a macbook?

[SooTyLaD]

hi guys,

iChat is unusable without plugging in external speakers due to the high pitched feedback that i (and whoever i'm talking to) gets...

it can be stopped instantly by plugging in speakers or pressing the mute button in iChat so its definitely a feedback problem on my end...

i have tried setting the speaker volume much lower and the input volume in system preferences much lower... doesn't help much... (also tried flicking the "reduce ambient sounds" checkbox... no go)

so all in all, in this case, the macbook doesn't "just work"... has anyone else experienced this? or know what i can do about it?

i'm still having this problem guys... any idea what i can do about it? i hope to god i aint got another faulty macbook

maybe your expecting to much from a simple piece of technology

i think that although apple products are great, some of you lot will defend them to the hilt even when they, as a massively successful corporation, are obviously wrong... i am trying to use the built in mic and speakers, with some pre-installed software (not a third party piece of hardware or software)...

so does this happen with everyone? or do you agree with joshua that its defective?
