Hi, when listening to my project I hear a loud pop and the level indicators go into the red. If I play the project again it's OK. Also if I try to add another midi track I sometimes can't hear what I'm playing although it's still being recorded, or I can hear what is being played for a few seconds then it hangs. If anyone has any ideas I'd be really grateful. 

Welcome to the forum!.
Please give your gear specs, what softsynths etc you are using. Then we have something to start with.

Hi apologise for not getting back to you sooner. Ok I'm using SONAR Professional,  on a hp Envy 700-570na using an i7-4790 Quad core processor @ 3.60 GHz with 16 GB RAM, Windows 8.1. My mixer / audio interface is a Beringer XENYA 1202USB. My midi controller is a Beringer UMX490.  As for the midi hanging,  it appears to happen with any synth? Also the project seems to take a long while to load.

David same thing happens takes an eternity to load a simple song. Splutters and stops without apparent spiking.
Hope they fix these issues in there monthly releases. I have to wait until the end of the month to see improvements if not I will have to wait till the month after!!!

Hi dappa 1, thanks for that. I didn't know they had monthly updates. Fingers crossed then.

To be honest, I don't think any future update by Cakewalk is going to solve your problems - if this was a generic problem the boards would be in total meltdown.
 
As it is, there seem to be a very small number of isolated incidents which sort of points the finger at your system/configuration/hardware etc.

Hi, when listening to my project I hear a loud pop and the level indicators go into the red.

What plug-ins are in the project?

Hi, David, I have this mixer Behringer XENYX 1202USB and never used it as an audio interface because the company didn't make available decent drivers for it.  What drivers are you using?

Here are some thoughts:
What audio devices do you have selected in Sonar?
Have you disabled your onboard audio card (usually a good idea)?
Are you using ASIO4ALL? (not so good)
Do you have the latest audio drivers installed?
Can you load a VST in stand alone mode and have it work?

These are just a few thoughts that might help debug the problem.

It almost sounds like it might be a loop. Hope you get it sorted out!

Unfortunately, Behringer instructs their clients to use Asio4ALL.
 
Retrieved from Behringer's forum:

"Seth,

You will notice underneath where the ASIO4ALL driver is on those webpages it says:ASIO4ALL USB Audio Driver
- Combined 32/64-bit 3rd party driver for Windows
- Supports Windows XP to 7 (32/64-bit)
- For OS X no drivers required
This is indeed the driver you are are looking for. Have you tried installing it yet?
