My Cubase 9 just started acting very strangely. I have already added my drum parts from SD3 and have recorded about half of my bass parts. I turn on my computer tonight, have made no changes, and now Cubase won’t record. The “Stereo In” channel is showing my signal, but the Audio Channel is not. And if I hit record and try to record, not only does nothing record, but Cubase stops recording and throws up an error message saying is noticed an Audio Dropout. I have looked at everything I know.

Windows 10, beefy machine, never had any problems before. Using UR22 interface. Please help … very frustrating.


The dropout is the key. Could you try to check your system by using LatencyMon, please?

Thanks Martin, I will download and run it this evening. What am I looking for? And why would a latency issue stop me from recording, and all while my other tracks are playing fine?


Here are my stats from LatencyMon. Any ideas what I can do to fix my problem? I already disabled CPU throttling and I don’t have a WLAN setup. LatencyMon gives a list of drivers by DPC and ASR routines but I am not sure what to do with them. Thanks!


Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. Also one or more ISR routines that belong to a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 7:19:12 (h:mm:ss) on all processors.

The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.

I also tried to record some more last night, when trying to record bass it drops out almost immediately and gives me the error message. I can record some with Halion but get pops and drop outs frequently, but no crashes, and no error messages. With my bass my Stereo In shows a strong signal, but no signal is showing on my actual track or on Stereo Out. Please help. Again, none of this was happening last week and I have changed nothing.

Last night I tried stopping all unnecessary back ground processes and updating my driver for the UR-22, still nothing better. :frowning:


What graphic card so you use?

Any silent Windows update?

Nvidia GeForce GTX 960.

No Windows Updates, I turned off auto updates last December after a 2 day update almost fried my machine.

OK, now I got the pops and cracks to start by removing all the effects on my existing bass tracks … and now when I try to record I just get a straight line, no recording. I can still hear my bass playing through my UR22 in my phones, and there is a signal in the Stereo Input, but no signal in my channel or in the Stereo Output. :frowning:

PLease help!

Here is a screen shot … you can see my signal in the Stereo In channel, and nothing in my Audio 01 channel, and nothing recording in my timeline.

How do you post a screen capture on this forum?? LOL

Thanks Martin, I figured it out.

Great! What was it?
