Well first here is what it looks like when you have it setup correctly for bitperfect playback....Notice the blue symbol.
It lights up a nice bright blue color when your in this mode.
Note: This light only lights up if your playing an audio file. It comes on immediately when you hit play and if all the settings are correct.
When you click on it this window pops up. Notice whats in the window:
Audio Path: Direct
Changes: No Changes are Being Made
Input and Ouput are matched, but in the Output you see that we are using WASAPI Event Style - direct connection.
Click on DSP Studio:
Make sure that the Sample Rate is No Change
Bitdepth = Source Bitdepth
Channels = Source number of channels
If you click on Playback Options you will see this menu pop up where you can select the various Audio Outt settings. Choose WASAPI - Event Style.
Then under the Output Mode Settings make sure that "Open Device for exclusive access" is selected.
These are the settings in Jriver that need to be correct.
Jriver will not muck with the buts...but make sure your WIN7 playback settings are correct as well...
All the best
