I was at the in-laws' house today attempting to record a family history audio tape (via line-in) onto my laptop for later conversion to a CD. I have done this for them before, but after much frustration I came to the conclusion that Audio Hijack Pro no longer works properly. Everything appears to be fine, but the recording doesn't actually start.
At the time I assumed the problem was a conflict between APE and the new OS X 10.3.5 upgrade I installed yesterday. The console log shows a permissions error involving Unsanity's Application Enhancer (APE) which doesn't seem to be able to execute superuser commands. A quick online search didn't turn up any answers but lack of broadband at the in-laws' place prevented any real thoroughness. In an attempt to work around the problem I downloaded Ambrosia's free utility WireTap to record the tape, but my whole laptop froze and started repeating a ringing noise when the recording got to about 95MB (about 30 minutes into it). By this point I had run out of time and had to postpone the whole exercise.
Some further research once I got home into the Audio Hijack problem showed that Unsanity are on the case, and have released a free upgrade to Audio Hijack Pro 1.3.2 to address 10.3.5 compatibility. I'll be trying again in a few day
Edit: Tried again on 17/8/04 - and it works
