I got a strange situation:
 
Big project with 50+ recorded tracks, now recording 28 tracks more simultaneously. Works real nice at low latency settings, no drop-out, everything perfect ...
 
... until I put it into a loop mode when recording (looping 4 mins). now first time around everything is still perfect, but at start of 2nd loop the master bus goes silent (no more output from control room speakers), sub mixes remain active (head phone mixes) and continue to play, recording also continues just fine
 
However, I cannot get the master bus to output any sound unless I restart Sonar ...
 
Anybody seen that before???
 
 

No one except me had the master bus go silent without any chance to revive ...???

Strange world ...

Sorry - I have never encountered this.  Sounds like a potential bug, however.

Have you contacted tech support on this issue?

Yea, it sounds like there is a glitch with that project. I would send it off to Cakewalk and in the meantime, i would do a clean install of Sonar, just for good measure. 

It cant hurt! That's what i told her at least!!

I have had the master bus go silent before. In fact it still happens now. Turns out it's a compressor that I was run in Guitar Rig in a ProChannel FX Chain, that sometimes fails to work until I click on a preset to "kick start" it. 

So I would check any effects that you have on the master bus to make sure that they aren't the culprit. In my case the problem occurs when I first open the project, but who's to say you aren't using a plug that randomly turns off when you're looping. 

Thanks for the replies!

To shed some more light on the situation: this is a new DAW (so there just was a clean install) that I did some "stress-testing" on. The project used for this purpose is actually the demo project that came with Sonar, so all the plug-ins and soft synths are pure Cakewalk ... and all available inputs are set to record to some of the sub-mixes that I sent out and back in via outboard gear or directly (cables connecting OUTs to INs) ...

Overall, the test delivered very pleasing results: No problem to track 28 channels while having several headphone, sub-mixes etc. at lowest latency settings. No glitches, no crashes, no problem to track 30+ minutes ...

So the only oddity I encountered was this master bus going silent, and this only happening in loop mode ... I had to post this as it'll make me look real stupid if that happens with people looking over my shoulder if I can't fix it ...

Anyway, if it's FX that causing it, I have a good starting point where to look ... it was definitely not a system overload (freezing synths didn't help, neither did higher buffer settings)

One thing to try if the master goes silent, change driver modes ASIO to WDM and back.
