Hi SONAR forum, long time no see! 
 
I'm having problems today with digital sounding clicks like I'm running out of CPU power. Only this time the clicks are actually printed to the track when recording! The project is a sketch with no plugs running apart from a few ProChannel compressors/EQ, so I got loads of CPU headroom. I've tried different recording chains and going both digital and analog into my BabyFace so it seems the clicks originate within either the interface/driver or SONAR. 
 
I've been a Cakewalk user for more than 20 years so I've had my problems with clicks, but I've never experienced them being recorded before! Any suggestions? I downloaded the update 2017.02 yesterday, is there any use trying to roll back?

Probably no help to you, but I had similar issues in fall with Sonar & MOTU. Back then I contacted both companies: Cakewalk, well actually Noel himself, replied that they would help but they have no MOTU rigs in house, hence cannot follow-up.  MOTU eventually provided a much better driver, so the issue has gone here ...
 
However, since you are now getting something similar with RME, which seems to be Cakewalk's number 1 interface for testing, you should have a fair chance that they can reproduce your issues ...
 
My suggestion would be to see if you can reproduce that after a reboot and possibly also with a new project. If so, get Cakewalk involved. I wouldn't be surprised if Noel himself gets on the case as something like this is either very deep in the audio engine or in the audio driver (which with RME is let's say a lot less likely than with any opther company).
 
Afterwards I would try to rollback and give it another try, should be quick. Also, what's the status with win10 updates? Are you current or some months behind?
 

Can you see them in the audio when you zoom all the way in?
Are they gaps, clipping or waveform inversion?

It's probably originating in the audio interface. Do you maybe have the clock source set to S/PDIF?

Caa2 mentioned the buffer and that occurred to me.  I set my ASIO buffer really low when tracking to avoid latency, and then high when mixing to avoid noises and other issues.
 
That said, BitFlipper may have the answer for you.

Yep, been there, done that.

I've always found that clicks and pops related to the audio buffer not being large enough generally end up recorded. And not just with Sonar but other DAWs as well.

Thanks for your replies guys!!

I've tried different project files now and it's reproducible as in this is the state of my DAW at this point (cannot reliably do a take more than 20 seconds long with out getting a click)..!

Also, what's the status with win10 updates? 

Current!

The only times I have had digital interrupts in my recording I found that using a larger sample buffer worked ok.
 

ASIO buffer size doesn't seem to matter!

Square clipping!

Yeah, sync error is pretty much what it sounds like, but the issue arose while recording analog into the BabyFace using the interface clock. I then tried recording through my Audient (connected and clocked via S/P-DIF) but the result is the same!

Sorry, but this is not my experience! I've never expected CPU/bus-related hiccups to end up on the audio file.

Thank's for the replies guys!!

I made big a post quoting and replying to each and one of you, but it disappeared after editing... So I'm boiling it down since I'm typing on my iPad now...

-I'm on current Win 10 and the issue is persistent across projects, even running an empty project with only one track.
-The waveform shows square clipping
-ASIO buffer size makes no difference, but in my experience such buffer related clicks never get printed to file anyway!
-Sync error is pretty much what it sounds like, but the problem arose while recording analog into my interface using the internal clock. I later tried recording through my Audient (connected and clocked via S/P-DIF) but that made no difference...

I think I will try updating the RME driver tomorrow, haven't done that ina while...
