I just got a Presonus Studio 192, and I'm using it with Ableton on a Win7Sp1 Notebook with SSD and 8 GB of RAM.
When using the Drivers, there will be clicks and cracks, no matter which Sample Rate or Bit Rate I'm using. Somethings the problems will come after a while.
After a long night of troubleshooting we used the Asio4ALL Driver, which worked perfecly fine with a nice latency and good sound.
Still, this is not the solution I want, I expected the PreSonus Drivers to be better than any generic drivers.
Thanks for any help - Chris
