This New Windows Update keeps screwing up Dorico's Sound

I had to revert mine as well. The update appears to have serious problems with the sound drivers although it is unclear why.

Did you reinstall the audio interface driver? In the past, I’ve had to reinstall the driver as well as reinstall the eLicenser software after a major Windows update.

@Craig F
Would you let me know what you mean by that? Did you mean the Audio Interface Driver in Dorico? Or on Windows?
How would you do that?

I’ve also never had to reinstall audio drivers (hence why I don’t know how to do that) in the past. This is the first time.

The Windows Driver. I have a Steinberg UR12 interface which uses the Yamaha USB Driver. I’ve had to reinstall that to get audio working again after a major Windows update.

Are you using the builtin audio or do you have an external audio interface?

Hi Craig, that issue with the UR12 (and the rest of the UR series) got already fixed, so please get the latest driver from

@Craig F

How do I reinstall the Windows Audio Driver? I do not have any external audio drivers. Just the default one that came with my laptop.

From what Ulf said that was a specific problem with Steinberg’s interfaces that has been fixed.
But to update any drivers for your laptop, you need to go to the manufacturers website and see if there are any driver updates there.

That said new, Windows releases are typically buggy so is best to wait awhile.
Also, builtin audio chips are typically awful for this type of audio application. You may want to consider a USB audio interface.

Hi Elwin,

our specialist had a look at your performance recording, but could not find a smoking gun, yet. Needs to dive deeper.
We would also like to get a system info from you. Please do

  • On the keyboard, hold down the WINDOWS key and then hit R.
  • In the Run window, type MSINFO32 and then click OK.
  • In the System Information window, click the File menu and then Save.
  • Set the desired folder to save to, enter any file name, and then click Save.
    Please post the according nfo file. Thanks

@Ulf I will have to reinstall the new Windows Update before I do so (Sorry About that).
I apologize for the late response as this is the first time I have seen it.

Hi Elwin, sorry, I didn’t mention, there’s no need to reinstall the update, just do as your system currently is.

I looked at HP’s website, and for my computer, the only driver they had available was for an outdated Windows 10 System, so that will not work.
Sorry for my late reply as I had to reupdate Windows 10 before I could do what you wanted me to do, and that took a long time.
I re-did the performance recording and did the system info. I posted the links down below.
Looking at the recent thread, I realize you told me that I did not need to reinstall the update, but I did not see it in time before I did it, so that’s a mistake of mine.
In the meantime, I do have a theory as to what could be wrong. Based on previous responses, It seems that the new Windows 10 update currently has issues with the audio driver, at least that’s what the website posted in a response says. I am thinking the deffective Audio driver is the one messing up the sound, and I think getting an External Audio Interface would eliminate the problem, since it would install its own audio drivers onto my computer. What do you think?

Hi Elwin.
I am no windows expert (at all!), what I can say for sure is that an external audio interface will have a way more reliable internal clock, so the whole audio quality will increase (especially during playback). And the driver will probably receive more care from its developers. Not sure it will solve your issue though.

Hi Elwin,
thanks for the new data, we will have a look on Monday. It’s still too early to say what is screwing up the sound on your system. Could be e.g. even a crappy WiFi driver that has an impact on the audio, we saw such cases before. We still need to see.
But it is always a good idea to use an external audio device. They are specifically designed to deliver professional audio and accordingly they have dedicated audio drivers that are built with the needed expertise. I can recommend the Steinberg UR series of audio interfaces, though there are also excellent ones from other manufacturers.


Hello, I do not mean to bug you, but is there any update as to you all looking at the data I sent? I was just wondering since I never heard back from you. Thanks.

Hi Elwin, sorry, too many threads going on at the same time. Yes, our experts did have a look and although they can see that the audio engine switches into longer processing cycles (what causes the drop outs), they still can’t say what is the real reason behind this behaviour. In any case, it must have to do with the Windows update, but what exactly we can’t say. From a scientific or engineering point of view it is of course of highest interest to find the exact cause of it, on the other hand, we have so many things to do, that we simply can not afford to spend too much energy into this. Especially because it is not a widespread phenomena, you are the first and only customer reporting such behaviour after a Windows update. So we hope for your understanding, if we - at least for now - cease the case.

Oh, okay. Thank you for letting me know.

It’s okay, I understand that you all are busy, and I look forward to your responses when you all have time to respond in greater detail.

I am guessing that this has to do with HP’s Audio system. I will attempt to fix the problem myself, as I have a few ideas now that I know it’s an audio engine issue, and I’ll let you know if something works.

Thank you so much for helping me with this problem, and I understand that I happen to be the only one with this problem. I look forward to hearing from all of you in the future when you all have time.

Hi folks,

sorry for coming back so late on this issue. In the meantime, we could now also reproduce the issue in-house and we did a fair bit of analysis on it. We do see what is going wrong, but we don’t know, yet, what is causing the issue, therefore can not fix it. But we are also in contact with Microsoft to get help from them.

Anyhow, what I want to say now is, we have found an easy workaround. People who experience this problem use the Generic Low Latency Driver. That driver uses by default the smallest possible audio buffer size of 10ms. If you increase that to 20ms (or if that does not do, even higher) then the distorted sound shall go away. To increase the buffer size, go to Edit > Device Setup. In the dialog click on ‘Device Control Panel’ button and in the then appearing window find ‘Audio buffer size’ and switch on ‘user definable’ and move up the slider below it.
Of course, this is just a workaround, it should also work with 10ms, but we are on the case and look for a proper solution.

Sometimes it is possible to have different sampling rates for different software. Make sure that Windows sound is set to the same sampling rate as your Dorico settings and vis a versa. This is one of the chief causes of jittery, noisy, silence and or malformed sound production.

And…any interface/sound card as well…

Hi folks, good news on this.

The guys from Microsoft were very helpful on analysing this and it was a whole lot of work. Now it seems we have found the culprit and that is NotePerformer. I’m already in contact with Arne Wallander. He will send me a fix version as soon as possible, so that I can test it. Once reconfirmed he will make it publicly available.

There is still the question, why it is now suddenly a problem, because the bug was already around for a much longer time. Must be also a little change in Windows that now uncovered it. Anyway, finally hunted down…
