Hello! I'm trying to do a video chat through ichat and the other person can't hear me though she can see me just fine. I'm doing this through OS 10.4.9, not XP. It's not a bandwidth issue because I switched from wifi to a direct connection with my cable modem and the stats say I'm running around 100% on audio. I tried recording sound on garage band, but it picks up no sound. In system preferences the sound input is set on "internal microphone/built-in," the Input volume is on max, but the Input level meter does not move at all. All this leads me to suspect hardware issues, but I'm hoping there's some preference I'm missing or something. Any direction in this would be most appreciated!
