When selecting two audio lanes with the same microphone there seem to be a conflict between them, either too much noise or static. As a result, nothing gets recorded
Steps to reproduce:
-Create an audio Lane and select a microphone
-Create a second audio lane and select the same microphone as the first one
-Try to record with both lanes at the same time.
OS: Mac OS Leopard and Linux Ubuntu 7.10
