Sonar freezes for ~1.5 seconds every time I stop playback

I'm stumped.

Other than the following:

Try another audio interface if possible?
Try another Windows User profile.
A full uninstall and reinstall of your RME RayDat drivers.
A full uninstall and reinstall of Sonar.  See: https://help.cakewalk.com/hc/en-us/articles/40752689912601-Clean-Install-Cakewalk-Sonar

I am out of ideas.

You might also want to drop a note to Sonar Support. 

Mention everything you have tried so far.
Be prepared for them to ask you to do the full uninstall and reinstall of Sonar.

Does the problem still happen if you "don't" use the spacebar to stop recording ?

I once had the double problem of drivers and a sticking  spacebar causing all kinds of problems.    

Sorry, but no...

Thank you very much for your support. The problem suddenly disappeared for no apparent reason and has now returned. If anyone else has any ideas, I would appreciate your feedback.

Which Windows version are you running? I just upgraded this machine to Win11 a few weeks ago and noticed that it throws hard pagefaults (i.e., reading from disc rather than loading into RAM like things should), with the vast majority of them coming from Windows Defender (but not all). That manifests itself as a hiccup of sorts, so I have been trying to drill into this deeper the past couple days. What is bothering me is that apps that don't specifically load everything to RAM are affected, so trying to find a dynamic loading feature in Win11. Still running this one to ground, but not sure if is related. LatencyMon is a good check on that one, can let that run while you are experiencing the issue.

If you play something through, does this still occur? Once played through, everything in a project should be in RAM (unless the project is large enough that it is spilling over RAM into a pagefile).

Having it return might give you some insight into what is causing it in the first place. 
 

Think about what you did before it returned! 
A certain plug in added etc. 

I remember a long time ago having this exact issue and I can’t remember what the solution was anymore. It might have been the time I discovered my SSD drive was not performing correctly. It was only a few years old and at 60 %. 
Someone told me to run the Samsung Magician and that quickly showed me the drive was running super slow. Apparently they can die on you due to how many read / Write cycles that have been used. 
Apparently audio and video editing is a read   write monster. 

So I learned it’s a good idea to run the test at least twice a year and catch it before you get into trouble. 
Resplendence Has 2 very useful apps I also use the Latency Monitor mentioned above as well as Why So Slow.
