MOTU 828x, Drivers, and Windows 10

[tedpiecemcnugent]

Is MOTU ever going to update their drivers for Windows 10 combatibilty? The last update was back in 2015 and it's almost mid 2019. My 828x is becoming useless due to all of the pops and crackles. I've also tried Terry's Voicemeeter workaround, but no luck.

Even though you have tried the Voicemeeter trick and presumably the trick of turning off the MOTU Audio Wave for 64 Bit or whatever they call their Windows drivers for that thing, don't stop there. Make sure every Windows Playback device and Recording device is set to the same sample rate in their "Advanced" tab of the Sounds control panel, and use "View/Show hidden" in the device manager and remove any lingering instances (greyed out) of the drivers sitting in the top section, "Audio inputs and outputs". Also, raise your buffer until clicks stop to see if something in the CPU is causing this - some internal DPC latency situation may still be lurking.

I have an Ultralite mk3 hybrid with equally ancient drivers and it works fine if I follow through with all the necessary protocols.

Here are the stats from LatencyMon:

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be suitable for handling real-time audio and other tasks without dropouts.
LatencyMon has been analyzing your system for 0:11:51 (h:mm:ss) on processors 0,1,2,3,4,5,6 and 7.

Reported CPU speed: 3693 MHz

Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results.

WARNING: the CPU speed that was measured is only a fraction of the CPU speed reported. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility which reports your actual CPU frequency and temperature.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

Highest measured interrupt to process latency (µs): 79.10
Average measured interrupt to process latency (µs): 5.307458

Highest measured interrupt to DPC latency (µs): 76.40
Average measured interrupt to DPC latency (µs): 3.127009


_________________________________________________________________________________________________________
REPORTED ISRs
_________________________________________________________________________________________________________
Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

Highest ISR routine execution time (µs): 16.561332
Driver with highest ISR routine execution time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation

Highest reported total ISR routine time (%): 0.000179
Driver with highest ISR total time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation

Total time spent in ISRs (%) 0.000179

ISR count (execution time <250 µs): 24317
ISR count (execution time 250-500 µs): 0
ISR count (execution time 500-999 µs): 0
ISR count (execution time 1000-1999 µs): 0
ISR count (execution time 2000-3999 µs): 0
ISR count (execution time >=4000 µs): 0


_________________________________________________________________________________________________________
REPORTED DPCs
_________________________________________________________________________________________________________
DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.

Highest DPC routine execution time (µs): 297.142161
Driver with highest DPC routine execution time: ntoskrnl.exe - NT Kernel & System, Microsoft Corporation

Highest reported total DPC routine time (%): 0.003569
Driver with highest DPC total execution time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation

Total time spent in DPCs (%) 0.012062

DPC count (execution time <250 µs): 329504
DPC count (execution time 250-500 µs): 0
DPC count (execution time 500-999 µs): 1
DPC count (execution time 1000-1999 µs): 0
DPC count (execution time 2000-3999 µs): 0
DPC count (execution time >=4000 µs): 0


_________________________________________________________________________________________________________
REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.

NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

Process with highest pagefault count: amd ryzen master.exe

Total number of hard pagefaults 1351
Hard pagefault count of hardest hit process: 795
Number of processes hit: 12

Just sent it in today for a replacement.

[klosar666]

Hi, did you find any solution?
Please let me know, thanks

[nordlead26]

its 2020 and we still with 2015 drivers and without windows support for MOTU 828x... only Mac have 2020 drivers for this unit... it is terrible, so many issues by using AMD and MOTU...

[mpax21]

Same thing... 1 year with 828x and i get crackles every time i hear what i recorded... 800euros for noting, well done motu
