Live IAC driver issues

This is just a little techy post for folks that use Ableton Live on an Intel Mac under Leopard (10.5). Just passing it on for the Google-bots – hopefully it’ll save someone a bit of grief…

I started getting major audio glitches the other night (not the good kind), and I couldn’t quite work out why.

I tracked down the problem to Apple’s IAC midi driver. I use the driver (which you can enable under Applications > Utilities > Audio & Midi Setup) to send midi notes from a track within Live to trigger a scene change.

When I enabled it on my MacBook I started getting major audio glitches in Live (6.0.10). After a bit of troubleshooting I worked out a configuration change in Live that (seems to have) resolved the conflict. A screenshot:
