This is new to me. I've been using X1D for about 2 years now and this just happened today:
I click on the X1 icon to launch Sonar> a message box pops open saying: There are no audio devices for the current driver model on your system. Please go to Edit | Preferences | Audio | Playback and Recording and choose a different driver model
I click OK. I get another error box that says: Silent Busses Detected (saying the Master is assigned to a silent buss).
I click OK. Then Sonar crashes. (SONARPDR.EXE has stopped working).
Looks like I may have to re-install but if anyone has any suggestions, please share!
I'm using a VS700 as the audio device and it's on and the light indicated it's working properly. In fact, 8.5 sees the VS and works properly.
