Topic: Strange latency / distortion problem on Windows 7 64
I've recently upgraded to Windows 7 64 from Windows 7 32 and have installed the latest 184.108.40.206 driver. I'm using Nuendo 4.x for my main DAW.
Here is the very strange problem:
At buffer size 32/512/1024/2048/4096 audio plays back from the main ADAT 1&2 outputs with no problems. At buffer sizes 64/128/256 I get NO audio output. If I create a secondary output in Nuendo (Devices -> Outputs) and assign it to outputs 3&4/5&6/7&8 then any track played back through this new set of outputs is garbled (or silent) at EVERY buffer size except 512.
The same hardware with Windows 7 32 (older driver and probably older firmware) performed fine. Can anyone shed any light on this problem?
