Yet another ‘audio dropouts’ issue with the ur22mkii. Thought I’d chronicle my journey here, hoping to get help, at least notes might help others.
Backstory: I had Win10 on a 2015 Dell Inspiron 15R with this ur22mkii (I use Cubase LE4) and it worked flawlessly for years. THen spilled wine on my laptop and it died. Bought a new Acer Aspire a515-52-7290 and installed all software and now experiencing dropouts (first time for me). I have 10 days before I return it to Best Buy to get my money back, so hoping to gain some confidence here that this will somehow work!
Day 1 issue, first search led to me Steinberg’s post about mmcss threads.
- Firmware & driver up-to-date (1.10.4 and 1.04).
- Latency mon shows all green bars (and says good latency)
- Cubase Processor affinity (6 logical cores only)
- Acer locked down BIOS, cannot disable HT or Turbo Boost
- 32 threads mmcs prio / 96 failed from mmcs test script
IF processory affinity works then in theory shouldn’t that fix the issue they reported? I can’t limit logical cores in BIOS cause no option (boo Acer).
Also, to be clear, this is definitely not a Cubase issue per se, as I get the dropouts even when playing any audio through the unit (i.e. youtube -> Chrome -> ur22mkii -> headphones). CPU is NEVER over 10%. And don’t suspect ASIO - the meter in Cubase is always at the bottom, so no latency. I also tried changing buffer sizes when using Cubase, but no success (side question - is there a way to modify buffer sizes in the ur22mkii driver directly? The latest driver I installed 1.10.4 either doesn’t have GUI config page or failed during install?)
Day 1) Power management (system sleep never, screen off never, usb power suspend disable, disk & cpu same), disable firewall, exit OneDrive, reboot, problem still there, exit OneDrive again after reboot, problem still there, start reading more online for 5 minutes, then problem goes away all of a sudden and I get 2 hours of solid performance.
Day 2) Next day, problem back. Windows explorer options, C: drive, uncheck ‘allow indexing’. As soon as I click apply Windows starts undoing indices and 100% perfect performance WHILE the operation is ongoing. As soon as it was done, terrible performance. Then did the same for D: drive and identical result (perfect performance while operation ongoing).
Day 3 is today) Noticed today that USB light on unit would go off/on, mostly coinciding with the dropout. Uninstalled firewall, tried DC power to the unit, moved from usb 3 to usb2 port, disabled Intel Link Power Management, rebooted, after reboot (still plugged into usb2 slot), seemed to work better.
So…is usb control issue? Something with disk?
