Hi, I'm trying to use my imac speakers with my ps3. I have a separate screen without speakers which is outputting audio to the iMac line in. While trying to get it to work I came across the application linein. This comes with about a 1 second delay so is pretty much useless. I found the recommendation of just ticking thru in Audio MIDI setup (utilities) but apparently that doesn't work on Intel macs. Now the current 'solution' I have is recording the audio in audacity with the passthrough button ticked so it plays while it records. This seems to have a very minor delay but works generally. Is there a better solution, it's doesn't seem to be that complex a problem and their are applications that can do it but I can't find a solution. Also is there a way to hard playthru and avoid latency issues entirely or at least a better way to soft playthru. Linein was about a second off at times.
