Both audio and vsti. Completely random. Never twice the same location for those pesky gaps.
It’s getting worse and worse to the point where i’m on the edge of changing DAW. After being a pro24 and Cubase user since version 1 on Atari, it would be a shame but i’m fed up.
I tried changing USB audio interface, no luck. Change of USB cables no luck. Change of buffer size, frequency etc , no luck.
If anyone had the same issue and solved, i would gladly have some help…
In the meantime i’m going to download a try version of other DAW to see if this is coming from Cubase or from my PC.
Hi,
Have you tried to increase your Audio Device’s Buffer Size, please?
yes. no change. with or without multi processing. with or without asio guard.
Hi,
What Audio Device do you use?
Are you on Mac or Windows? If you are on Windows, could you test your system by using LatencyMon utility, please?
Do you use any plug-in in the DEMO/Trial mode by any chance?
i’m ,trying that asap. No i don’t use any plugin with a try out mode inserting random silences… it a good idea though
no problem whatsoever. i was running two audio apps at the same time to stress the system and the drivers.
And the gap was created in the audio file without latmon noticing anything strange.
all the lines are barely reaching 15% of the lenght and are all green
Make sure you’re not using real-time export. In particular, if you have trouble with gaps on playback (e.g. due to overloading the CPU and/or something else on the system that makes Cubase unable to keep up with feeding the audio interface sample buffers in time), real-time export would likely have the same issues, and that could also explain the randomness in the gaps. But, if you don’t use real-time export, Cubase can take whatever time it needs, including a lot longer to export a mix than the length of a song.
For context, I tend to have lots of issues in playback in periods where I’m using a bunch of taxing plugins (e.g. Ozone 11, any of the IK tape emulation plugins, etc.), but I’ve never had similar issues in my export results.
I do not use RT export. And the project is just one audio track…
The same occurs during recording.
There are only 1 or max 2 gaps each with a 2 or 3 seconds duration.
The length of the track is 2 minutes.
Just to be precise, my PC hosts a i7-14700KF with 64 GB DDR5 Ram, several SSD both gen 4 M2 and regular. GPU is a RTX 4070 from Nvidia. The audio is handled by a UR22 Mk2 from our beloved Steinberg.
I have tried a behringer u-phoria UM2 and several drivers like asio4all and even the one from a small keyboard from ik multimedia called iRig with an internal audio board. All with the same results.
I have tested other Ram too. I’ll try another GPU tomorrow, and i will try Studio One and Reaper to see if this pattern repeats itself…
What’s your export file format? Asking, because I’ve had trouble with exporting to FLAC, while WAV and MP3 are fine on my system.
Hi,
Do you record into WAV or FLAC?
into WAV 44.1 16 bits
I have let LatMon run for 6 hours now and it show problems
Funny because i hardly touched the machine…
the last lane is now redish with the highest reported DPC routine execution time seems to single out ACPI.sys as the culprit.
conclusion / your system appears to have troubler handling real time audio… one problem may be related to power management, disable CPU Throttling in control panel and Bios setup.
Combating high DPC latency from ACPI can be tricky. It typically hits laptops the worst. Here are a few things you can check.
- Make sure your BIOS is up to date.
- Go over all power management settings in Windows and make sure everything is set for highest performance. (There are numerous guides available online.)
- Make sure there are no power saving features turned on in BIOS.
- Make sure all USB hubs in Device Manager are set to never sleep.
- If present, disable WiFi and Bluetooth
- Disable any 3rd party software that might use network activity in the background. 3rd party antivirus included.
Thanks i did all that and nothing changed. Same big random gap.

Even worse. Now real time export crashes.
Out of curiosity i ran a benchmark using cpu-z on this machine and compare it to its almost twin brother sitting under my desk (dedicated to video and 3d)
i7 14700K (not KF) 64 gb ram Gigabyte Z790 motherboard instead of NZXT for the audio PC) and same GPU with same bunch of m2 and classic ssd drives
they were bought and assembled together.
On my video system i have reached a single thread score of 902 and multi thread one of 14995
On my audio system, i have only managed to yield respectively 896 and 12255 ! hence a delta of more than 20% !
I have isolated the loss of performance to the p-cores. Single core and e-core performance is the same as the video machine
It’s rather weird. I can see the score beginning at 14900 and plummeting in a few seconds to 12255
on the video machine it begins at 15500 and ends at more or less 15000
Could this be related to the issue that intel had with 13th and 14th gen CPU ?
I bought them before the problem hit the market.
I switched the RAM. Same thing. Even worse
I’m going to switch CPUs to see if this poor performance is seen again in the other PC
Ok CPU switched
So first things first, my CPU installed in the DAW PC is definitely faulty.
The one i switched gets exactly the same score as with the Video PC.
This CPU is returning to its maker.
But
Same problem is happening when i export audio thru Cubase.
I’m going to uninstall my cubase and try one of these pirated version to check if this is related to eLicenser.
If nothing changes, i’ll try a DAW that allows a tryout version.
Pirated versions Cubase 12 and 13 and Nuendo 12 and 13 have the same issue. So it’s not eLicenser related and it has never been adressed by Steinberg since version 11.
On the contrary, Ableton Live and Studio One have ZERO issue under the same conditions with a Steinberg UR22 mkII. So it’s not hardware related.
With deep sadness, i’m going to switch DAW as Cubase has become unusable for me.
Thanks to all who took the time to read me.
