8.5 to 10.5 and Audio drop is impossible

Hi
Paid a small fortune (as an occasional user) to upgrade from what was a working 8.5 system to what is now and unusable 10.5 system.
Spent 2 days trying to configure and cannot get rid of massive audio drop out on playback
Recording is worse.
Its A Simple set up.
Win10, 64Bit, plenty CPU and Memory, Cubase 10.5 Pro, UR44 (all drivers updated and checked)
Ports all working and configured but playback is stop start every 2 or 3 seconds. Even a single MIDI Bass drum track.
Especially if the mouse is moved. Meaning mixing is impossible.
I’ve tried 32bit and 62bit set up. Using Steinberg driver. Tried low buffer and high buffers.
I upgraded cos I was reassured that the Audio drop out from W10 thread limit/change, was not an issue for 10.5

I’ve read many of the ‘audio drop out’ articles and tried various.
No background tasks running.
The PC has nothing running now that wasn’t there before. Nothing in background. I’ve even disabled the SB Audigy Soundcard.
Any ideas ? Links, pointers to articles I may have missed.
I@m not convinced this is even a cubase issue … maybe core W10 ?

Hi,

Try to test your system by LatencyMon utility, please-

Hi
So with NO SOUND , fresh reboot and pretty much doing NOTHING … No Cubase loaded etc.
Latency Mon tells me I have a problem - well that much we knew. …

Any suggestions on the next move ?
This is a desktop - There is NO Wi-fi internet connect capability. Ethernet only. No Bluetooth.
I am using a wireless mouse (but always have for years - same one I used for years with Cubase 8.5 and all was Dandy.

UPDATE…


WITHOUT NETWORK CABLE & Anitvirus etc all OFF

Tells me the system is good for Audio … BUT DROP OUTS ARE ALMOST CONTINUAL ONCE CUBASE IS RUNNING>

IDEAS ANYONE ?
CUbase is currently unusable. For playback and worse for recording.

UPDATE
Although LatencyMon isnt showing any issues with ASmedia driver USBXHCI.sys , It seems that if I disable “ASMedia USB3.1 eXstensible Host Controller” it makes a big difference. I still get drop outs but its a massive improvement and I can actually record clips. A track will play through with just a few blips.
How can i find out which USB port ASMedia driver effects. Aside from physically testing each via a device.
Motherboard = ASUS® X99-E: ATX, Broadwell-E CPU, USB 3.0, SATA 6 GB/s
USBs = 2 x USB 3.0 & 6 x USB 2.0 PORTS plus 2 front USB’s

or is this a complete red herring ?

I upgraded from a bomber 8.0 system to 10.2.20 a month or so ago, and am still dealing with the last few remaining issues (video being the biggest right now, which for a Film Composer is a bit of a problem…). Audio definitely seems to require significantly more horsepower in C10 vs C8. I’ve had to offload as many instruments as possible via VEP to other PCs to give the Cubase machine as much grunt as possible to handle the audio in addition to the DAW itself, which seems to work okay. Weirdly I did find the initial install was awful with any audio in the project and after weeks of preference tweaking almost gave up (don’t know what I was thinking doing this mid project). I then reinstalled from scratch, updated the Nvidia and audio drivers everywhere and it worked much better. No real explanation why though I’m afraid.

Might be worth reinstalling and getting your drivers updated.

Hi,

As NVIDIA owner, please try this to optimise your system for DAW:

  • Uninstall the NVIDIA driver.
  • Download the latest Studio driver version from here.
  • Start the installation (as administrator).
  • Don’t install the whole package, use the Custom (Advanced) settins.
  • Disable everything (don’t install NVIDIA Experience, PhysX, etc.), keep just the video driver enabled.

All. I thought I’d close this one off.
A few weeks ago i gave up and thought “what if I downgraded from my desktop to an old dell laptop”
So here I am. Still running Exact same Windows Release.
And hey presto. All latency issues gone.
Laptop running superbly with 36 tracks of music playing in one project. Remote keyboard Novation 61 controller And a small also midimix Connected. And internet connection and anti-virus also active and live.
Every solution to the above problems pointed to memory or cpu or Usb ports And drivers But mainly W10 As being the culprit. Yet on a machine with slower cpu and less RAM And exact same W10 All Is working fine.
Moral - don’t trash your old laptops.
It’s a pain to have to find space for it on the desk and not as smooth to connect the external monitors, etc.
But I’m up and running.
Thanks to all who tried to help. Much Appreciated.

For anyone interested… moved to a DELL XPS13 (9370). Massive latency issues returned… and I have seen many others complaining about Dell XPS on this same issue. But once I connected my UR44 USB direct to the Laptpop (via USB-C converter) and not via the “Thunderbolt hub” all my latency issues were gone.
