Hi @mrwatson and welcome back to the Steinberg forums.
You did buy decent Hardware. As you know, the issue is with the YSUSB Driver only.
As @Vatharian has suggested, it could be a a good idea to contact YAMAHA directly and inform them of the issues we are encountering, with the YSUSB Driver on Windows.
Hopefully, the more emails they get, the more likely they will look into it.
FWIW… I had way more issues to make UA work on W11, and no issues with the UR44C. Even if UA support staff was stellar, they seem to focus more on Mac, and PC support was an afterthought.
Not saying Steinberg/Yamaha drivers are flawless by any means! But many configuration details (aside from the audio driver) can be the root cause, and forums from all vendors report catastrophic driver issues…
For every vendor/driver/configs, we have 1000s of silent happy users, and dozens of loud unhappy users… so it’s very hard to predict what will be our user experience with any of them!
All that said, if you are tired of your current issues and want brand new ones 
you can change vendor. In that regard, RME has a good reputation ($$), but I would check out Audient too.
@Y-D.
Thanks for this.
If you don’t mind sharing your PC specs, ie: MOBO, CPU, GPU, that you run W11 on, without any issues with the UR-C, I would be very grateful.
Did you have to do any tweaking, or was it a case of a straight forward install?
It’s unfortunate, that on this particular topic, more users like yourself, have not commented on their successes with the YSUSB Driver on W11, even W10 (but then, there is no reason to visit this topic if all is good for you) , followed by PC specs and how easy the setup process was. But as you’ve wrote and I totally agree, there are much more success stories than failures.
All the PC builds’ (5 in total) have been Intel, Gigabyte and NVidia, and since 2021, none of the YSUSB Drivers work on any of them.
Since you mentioned it, I did invest in an Audient ID22 and used the UR824 as slave (Driver’s were OK), but then the ID22 started to developed faults.
Due to a lack of funds and desperation, followed by frustration, I decided to source a used Audio Interface, and that’s when I got a pretty good deal on an RME Fireface 400. Pretty old I know, but all the hype about Driver stability swayed me.
The hype is real, I’ve had zero issues with this unit for the past 2 years, not one glitch, it doesn’t skip a heartbeat, given it’s age, this is incredible. Also, using the UR824 as Slave.
But I’ve been missing my UR824 as Master for the past 3 years, and don’t want to let it go, it’s a lovely unit that sits with Cubase very well. And witnessing one go for £150.00 (19 watchers) on EBay, and a second one go for £125.00 (11 watchers) also on Ebay, was just excruciating.
Apologies for the long post, but if you could kindly share your Windows PC’s specifics, I would be very appreciative.
Regards.
Prim.
I built dozens of PCs since my first 80286 running Cakewalk on floppy disks, and my approach has always been the same: No bells and whistles. A boring machine is a stable machine. Strip-down simplicity is the key.
It starts with a top-quality oversized PSU, a properly-installed heatsink and premium quiet fans. Told you it was boring.
Unless of course you buy a laptop… then you don’t get to pick any of these, but you pick a solid metal-case laptop from a reputable vendor with the best cooling option you can find. This means avoid the crazy-thin super-light laptops.
And please of course… no overclocking…
My latest CB machine happens to be a laptop.
(I have 5 computers in my office, please don’t ask why)
It’s a 16in Lenovo (selected also for its convenient numeric keypad for CB), with an i7-1370P. In a nutshell: Avoid the U series, go for P series (for laptops of course).
It’s paired with 32GB of RAM and 2TB SSD.
Again for simplicity/stability, use the integrated graphics. GPUs are more for gamer machines. I know they can save you a few minutes once in a while (with some heavy Spectralayer tasks for ex.) but the intrusive drivers and bloatware that come with their load of surprises are not worth the trouble.
But above any hardware details, the top ingredient for stability is a clean OS install.
When helping a friend with an unstable machine, I start by disabling, or even de-installing, all the semi-useless bloatware running in the background.
And disable anything said “automatic”.
Disable automatic updates, not only for windows, but for you GPU (if you succumbed), and any programs or tools, especially anything from Adobe. Better yet, de-install anything from Adobe… ok ok I will confess having an old grudge with them…
Disable any and all cloud syncing, like icloud, onedrive, evernote, etc.
You can use them, but manually.
Disable weather widgets, etc… you’re getting the picture now: make it boring!
Open Task Manager and look at it for a while to see who is eating resources in the background once in a while and question if it is really needed.
You can also disconnect your PC from the internet to test if it helps.
Once you stripped down your machine from all the bells and whistles (it often could take hours), open your DAW and see if you still have issues.
If it’s OK, start slowly re-enabling only the goodies you are really missing, but keep it clean and simple.
As you can see, I don’t mind long posts
I truly wish all of you some peace of mind… I know computer can drive you nuts. I remember opening the door and throwing an expensive printer out in the snow because of driver issues…not my proudest moment 
[ Edit: Yes I brought the printer back inside, dried it up, and managed to fix my printer driver issues. I still have that same printer over 10 years later. ]
Thanks for taking the time to share your knowledge.
I built my first DAW in 2011, i7 875K, Gigabyte mobo, Windows 7 Enterprise, and 2x M-Audio Delta 1010LT cards. The machine was a great performer and was strictly an offline PC… after discovering an Internet connection was slowing it down. Since then all the DAW builds’ have been offline PC’s.
On experimenting with Windows 7’s Services, It managed to get along fine with just 11 Windows services, running in the background.
Maybe unfortunate that all the DAW builds since, have been an Intel K, with no on board graphics support. So using a GPU has been unavoidable, apart from the last build, i7 11th gen.
I am very familiar and particular when building a DAW, and always make sure that the components used are of mid to high quality, that work very well with each other, and are fit for purpose… going slightly overkill, if you like.
But what I’m struggling to understand is, why, out of the 5 different brands of Audio Interfaces that I own, The YSUSB Driver is the only piece of software that is completely defunct. I can use all the others, all day long with no issues, on all 5 PC builds, under Windows 10/11, but not the UR824.
This is what reinforce’s my belief that the YSUSB Driver is not as robust as it should, or could be, and is an under performer in comparison.
I mean, what has M-Audio, Lexicon, Audient, Edirol and RME, done with their software that YAMAHA hasn’t done?
As you’ve stated in your advice, to disable un-needed Services etc, a practice I’ve been doing for several years now… got me thinking … Is that what they do when testing their audio driver’s?
Incidentally, past clean installations and tweakings of Windows 10/11 + System, have made no difference on any of my Desktops. A short relief on an x99, i7 6950x, through a UEFI tweak, worked for a while, only to return.
One more thing. The UR824 works perfectly fine in Linux with Bitwig, it just lacks the DSPMixFX software.
Phew.
I could go on and on about this issue, I’ve had it for 3 years now, but still hold on to… “Maybe, just maybe, one day, before it looses support”.
Thanks for your post Y-D.
Very much appreciate it.
Peace.
I had this problem since 2020 never got fixed, I changed the cable, the computer followed all of the fixes I found everywhere of BIOS, encripted disk, only ssd , etc… nothing works … am going to use the ur816c just as a digital preamp because I just can´t work with these dropouts all the time.
Update
I wrote emails to Steinberg, Yamaha Europe, and Yamaha Poland. I have written in Polish, English and German, just to be sure.
I can say that level of support has been provided is exceptional.
Exceptionally bad, that is.
I have not received even a single email in response. No contact, no reply, not even an automatic confirmation “thanks for your message, someone will read it and reply”.
I am persistent, so I WILL call them by phone, next. If this won’t help, I am going to try to get Yamaha HQ involved.
I COULD sell it (especially since I haven’t used software keys associated with it), but damn, I like the product itself and its capabilities, and I WANT it to work. I am beyond pissed, and I want them to have their crap together.
I will keep you updated.
I gave up
Here’s an update
I used all my 30 days of return period to find a solution to this issue.
UR44c
Windows 11
Dell laptop
When I thought I managed it - I was wrong. I could not help that poorly written driver to work properly. Although I tried really hard and did all the crazy acrobatic and tweaks…
Customer service is terrible. No help.
I sent it back an bought Focusrite 18i8. At first I was sad cause I wanted the Legendary Steinberg on my desk and not this red Focusrite shiny box …but after just few days I realised that I should do it in a first place and save myself the hassle with UR44c - wasted time.
It works like a charm no problems - similar specs, but more inputs, much better software control, perfectly written driver (multi-clieant!!) and … customer service is outstanding!. You can literally chat with the staff LIVE at any time to solve any issue.
Sorry Steinberg
you lost a customer right here.
Hello friends from all over the world, I am a UR24C user in China.
My laptop encounters the same situation as Vatharian.
For example, when I am listening to a 4-minute song, this unpredictable interruption may reach at least 1 time every 7 seconds.
I searched Steinberg’s official website in China, and the official content still could not solve my problem. I also checked the common social networking media in China: Weibo, Bilibili, and searched various engines, but found nothing.
Until I read the original English words of the error message (yes, to use the UR24C sound card, you must install the Yamaha Steinberg USB Driver and dspMixFx_UR-C, and these two software are all in English),
Then I came to here.
If I hadn’t seen your comments, I almost thought I was the only human in the world who encountered this. Even half a month ago, I bought an Audio-Technica m50x headset for this sound card.
But the current situation is too infuriating. Not to mention listening to music, I can’t even play any electronic games, let alone plug in the bass to practice.
Tomorrow (now it is 3:31 am China time, I started to search and test various solutions at around 10 pm, including but not limited to those done by Vatharian, such as:
I will call Yamaha China’s after-sales service phone number to report the problem (on the last page of the product manual).
If Yamaha has no solution, I will also sell this sound card as second-hand, and Yamaha will not only lose me, but as mentioned earlier, no one in China’s social media talks about this matter? Then I will “help” Yamaha tell all Chinese users, after all, the Internet has memory.
There is a Chinese Musical Instruments Exhibition in Shanghai every October. If I go to the exhibition next year, I will “greet” the Yamaha staff cordially.
After all, 5 important hours of my life are gone just like that.
Sorry, my English level is limited, and I can only use Google to translate the above words.
Having the same issue with MSI GE78 V14 laptop.
Nothing works. I did every possible from the list… emailed steinberg support and yet no answer…
I had exactly the same problems with my UR44C on a Windows Surface Book 3. I tried everything that was suggested, but nothing worked. The problems got worse recently when - out of the blue - the UR44C is no longer detected. Again, I tried everything I could think of to solve this problem, to no avail. I guess, in a next step I will say goodbye to Windows.
