I’ve tried “everything” to stop audio drops with UR 22C but nothing helps. I’ve tried these; UR-C: Audio dropouts in SuperSpeed (USB 3.1 Gen 1) mode Windows: Issues with Yamaha Steinberg USB Driver V2.1.0 or later
changed ASmedia USB drivers from Microsoft to ASmedia <> ASmedia to Microsoft changed Superspeed USB 3.1 Gen 1 to USB 2
nothing helped
Then I’ve tried some other things like
Tried all USB ports, including USB 3, USB 2, Front/Rear
Changed BIOS settings;
XHCI Handoff Enable/Disable
USB Legacy Support Enable/Disable
Power Management Options
All I can say is nothing changed with “switching Superspeed to USB 2 mode”, same period audio dropouts…
I’m on an X99, 6850k build myself, with a UR824 and had all kinds of issues. Only got it working recently after almost 2 years. I installed driver version 2.0.3, and I followed all the steps in this link.
Thank you for your comment…But there is no “Windows UEFI - Other OS” option in X99a Tomahawk…
All I can see is "Windows 8.1/ 10 WHQL Support " and it means “The system will switch to UEFI mode to meet the Windows equirement.”
and I’ve tried that enabled/disabled before. I use it enabled
Have you tried using the NVIDIA Studio Driver?
In the NVIDIA Control Panel, change Power Management to Maximum Performance and turn off Threaded Optimisation.
Did you install the Yamaha Driver v2.0.3?
I am just clutching at straws here, but that’s how I eventually got my UR to work. I know it’s a bit of PC acrobatics, time consuming, frustrating and annoying, and I almost gave up after 18 months. I feel as though there is a way to get your UR-C to work as it should.
Have you tried Latency Mon to see if it gives you any clues?
I have a ur22c as well on win 10. I find the driver seems to drop out periodically. Some days I can go for a whole session of several hours without problems. In the studio setup window I put no in driver- ok then swap it back to Yamaha ASIO driver then it works again.
I’m still running an earlier driver and saw no reason to update as it still happens on the latest driver.
I’m assuming you have wifi turned off and anti virus stopped?
Has anyone tried installing a newer USB 3.1 card? I’m having the same issues and I can’ reproduce the audio drop outs. It only happens when I livestream (of course). I’m reading some say to downgrade to the v2.0.4 driver? I’m using Reaper as my DAW and I also use AsioLinkPro to route audio between applications. In addition, I run a Touchdesigner (graphics/cpu heavy) project while running Reaper. thanks

I emailed support and they immediately blamed the other programs I use along side of the unit. They didn’t even suggest I try anything, it was very disappointing. Then I pointed out that this was a well known issue and has even been ‘reduced’ via driver updates. The whole back & forth was frankly offensive considering how much time & money I’ve spent on this. Support is clearly clueless and useless. I 've never encountered such an unhelpful and uneducated support rep.
I started using LantencyMon and what I discovered was that the DPC latency on my system is due to the USB devices I have connected/running (4 web cams, peripherals, etc). My next step is to install another USB 3.2 card on my system to dedicate it to the URC unit.
update: went down a deep rabbit hole and the gist is that this issue is really an issue involving USB busses and how an OS manages the interrupts. check out the LatencyMon tool and that’s the first step. its likely that it will tell you that wdf01000.sys or the Nvidia driver is the culprit. Or maybe something else.
I suggest adding a USB 3.2 card and looking into Process Lasso & GoInterruptPolicy ( or Microsoft’s Interrupt Affinity Policy Tool).
For me, it was basically too many USB devices on one USB “root”. Its a deep hole, but I can try to help. I’m still testing here.
