Hi again.
First of all thanks for all your replies.
And I agree with you that my post is very sad and not seeking constructive solutions in any way.
I'm a musician more than anything else. I spend my time to be creative for myself and for all the musicians that comes in the studio.
Believe me when I say that I have done more than most musicians would do to make X2(a) work but I want to spend my time on music - not on buffers, drivers, Windows tweaking and all that.
So ... For those of you That knows a lot about it this is my setup:
Dell XPS Studio PC, i7, 3 GHz, 12 Gb RAM, with a clean installation of Windows 7 x64. Newwork adaptor is disabled in BIOS along with the built-in soundcard. For this maschine I use 2 x 28" monitor running in 1920 x 1200 pixs.
Also for this studio I use the Allen & Heath ZED R16 firewire mixer with the latest driver and matching firmware.
After the clean install of Win 7, all of Dells own applications and tools was gone and the Non relevant tasks are set to manual start and are inactive when Sonar runs. there is no antivirus.
There are no other programs running on the pc exept Powerdirector for video editing.
On top of the clean Win installation X2 was installed from the optional CD. The installation went fine. After the installation X2 was launched for the tests and so on, rebooted and X2a was installed.
Then the countles modules, instruments and patches was installed. All in Admin mode and with no breakdowns.
Then the trouble began starting with countless dropouts. I went through the entire website and this forum and tried systematically every possibility one at the time going back to the previous settings as soon as the latest setting was changed - you know how time consuming this is... Right ?
I have consulted all the Cakewalk documentation including the reccomandations in the 9 hour long video.....
Just when I thought I had it after 20 miuttes of recording and playback Sonar went into a distortion hell almost ruining my Adams monitors.
This let me to believe that there was something wrong with the firewire card in either the mixer or the pc but a change with the simalar mixer in studio 2 and a new firewire card in this Dell changed nothing.
As I said I like to spend time on music.
However narrow minded it might seem I expect my daw software to behave as it is supposed to. I dont mind spending 15 minuttes tweaking latency and buffers for the driver and harddrives - but then I expect results and getting back to what its al about: creating and recording
