I recently posted this problem with core audio recording I often switch between DAE/ TDM and Core audio. Recently there seems to be an anomaly in Core. When I play back in record enable I can hear myself over the play-back as if audio input monitoring were turned off, which It isn't. Everything works fine in DAE/ TDM. No problem there. Maybe it's a stupid problem but I was hoping for some kind of feed back. I'm stumped. Jake Power PC G5 2Ghz 2.5GB ram Logic 7.2.3
