Snow Leopard 10.6.6 will also do:
I have downgraded for now from 10.6.8 to 1.6.6 and no latency issue now.
However, I have tons of clicks. If I lower my R16 channel input gain a little bit, the clicks are gone.
I've read somewhere that clicks and noise could be related to USB drivers.
Anyone had a similar issue?
By the way, I've downgraded by reinstalling the Snow Leopard DVD and all my applications and settings weren't touched.
Here are the steps:
- While OS X is running, insert your OS X Snow Leopard Install DVD.
- Double click Install Mac OS X.
- Keep the DVD inside your computer while you wait for it to restart.
- Wait until the second phase of the installation procedure completes.
- You are now downgraded to OS X 10.6.2 (or something less than 10.6.6).
- Download and apply the OS X 10.6.6. combo update to bring you back to 10.6.6.
