When I come here with a question, it usually isn't easy to answer since by that point I've used the usual remedies to no avail.
Are you looking in your audio settings as Bob has asked to make sure all of your inputs and outputs are checked.
Yes, as I said on the fourth post.
The timing master defaults to your audio interfaces 1/2.
Is this a different audio interface from when you used 8.5.
Maybe you didn't pick this up earlier, but it was working fine yesterday with X3.
Did you install the latest ASIO drivers for your interface before installing Sonar?
I've been using Sonar since 6.0 PE and it was working fine yesterday, for a while.
It just seems weird that a Lynx card would screw up.
I don't believe that's the problem, having spent a half hour or so speaking to their tech.
Do you still have 8.5 installed and can check if it see's it properly?
I've thought about that, but not until long after I've thought about how it shouldn't be so time consuming troubleshooting buggy software has become when I'm trying to focus on music.
Why should I go back to 8.5.3 PE which hung up for 5 minutes every time it scanned cakewalk's L2 clone?
