Hello all,
 
I spent a serious part of the evening reading through most of the previous posts about the "pegged meters / no audio" issue. While some threads did give me a few ideas to try in the pursuit of getting rid of this extremely annoying problem, the problem still persists.
 
Recently, I got the excellent iZotope Producers Pack and Neutron2 & Ozone seem to increase the probability of getting the problem which is a shame as I have to freeze a most tracks (which I guess helps by disabling the FX), despite having plenty of CPU power left (E5-2667v2, 8*3.3GHz). The last few weeks, I think I´ve been spending more time to reboot the computer / restart Sonar than acutally making any music.
 
Other parameters I´ve played with (with no effect):
* Switched soundcard
* Changed buffer size
* Uninstalled antivirus
* Disabled Hyperthreading
* Disabled Plug-in load balancing
* Changing Thread scheduling model
* Changing Zero fill method
...+ some other things I forgot.
 
Is this issue being adressed by Cakewalk/Bandlab staff?
 

Hi, I haven't heard of pegged meters, you mean all the way up/lit?  I did have a similar issue with no audio but meters worked like there was audio.  For me, changing my audio interface was what ultimately worked....i was using an old, unsupported device previously.

Disable core parking and re-enable hyper threading.
 

maybe try "Audio Engine on/off "  &  " Reset / Panic (Reset MIDI and AUDIO) located in Transport Module.

Remove the most recent vsts you have added one by one. 

Have you tried un-checking the 64 bit internal processing box?

What you're describing is something I have experienced in the past, but for me it's always been a soundcard issue . . . yet, you're using RME BabyFace, which employs some of the best audio drivers in the marketplace ?
 
I use iZotope Neutron2 and Ozone 8 extensively in my projects, it's true they can hog CPU, but I haven't run into issues like you're describing, even with my humble M-Audio USB audio device, though, I've updated to Cakewalk by BandLab, so that's different.
 
Only thing I may add here, that I haven't seen listed, is to try and disable any high definition audio add ons your video card may be using in Windows Device Manager ?

I'm curious, what video card are you using?

I have also done this without any success. Even disabled in bios.

I think we need more clarification here
 
Which meters are pegging?
All of them? Tracks? Busses? Master?
