I have asio spikes randomly. I have my template loaded and this also happens even when I haven´t recorded anything (even when I don´t touch anything). And I have no idea why. There is audio crackle when the spikes happen (if something is playing). I was hoping someone here could help me figure out what else could cause this?
If I run latencymon while Cubase is on, the highest latency is from the ohci1394.sys driver (around 0.42 ms). If I run latencymon when cubase is off the same driver has around 0.003 ms. This is normal I guess? I have to use the old legacy 1394 driver for my fireface 400 soundcard. Otherwise windows 10 will have a BSOD and reboot.
The “Current measured interupt to process latency (μs)” is around 11 μs when I run it with no programs open in windows. So there is nothing worng according to latencymon.
When the spikes happens I can´t see anything happening in latencymon. So I have no idea how to find the problem and solve this.
In windows Performance options/advanced I have it set to “Background services” instead of “Programs”. Is that correct? Also I´ve changed the virtual memory to 4096 (both initial size and maximum size accordning to a guide) instead of letting windows handle that. (EDIT----- I tried switching to Programs, and I tried letting windows deal with the virtual ram settings. Still the same problem)
My Buffer Size is very hig, 512. (EDIT----Am trying 128 right now.)
In the project I´m using Waves SSL EQ 4000, L3-LL Multimaximizer, C6, scheps 73, Altiverb 7.2.9, Valhalla Room, Fabfilter Pro Q 2, Cubase MixerDelay and maybe some more that I might miss (not by the music PC). I´m using a lot of instruments from Orchestral Tools. About 200 instrument tracks are loaded, and another maybe 250 instruments track that´s disabled. The template uses 33gb of ram. In kontakt the instrument preload buffer size is set to 42 kB.
The overall ASIO load is low, around 17% when the template is loaded and not playing. And it increases a little bit when playing (around 17-25%) (I´m using 29 instr at the same time in the example I have in my template right now).
In Cubase I´ve tried both with and without asio guard (including disabling all vst plugins that I use). There is no difference (except that the average load increases, just like it should).
In the BIOS settings this is disabled:
CPU Ebhanced Halt (C1E)
CPU Thermal Monitor
CPU EIST Function
I have not overclocked anything.
In Windows I have disabled the “High definition Audio Controller” under System devies. Bluetooth and wireless network adapters are disabled as well.
Windows 10, Cubase 9.0.10, Kontakt 5.6.5, Gigabyte GA-X99-UD5, Intel Core i7 5930K 3,5GHz, 64Gb memory, Sonnet Allegro FW800-E, RME FireFace 400, Asus GeForce GTX 960, Samsung 850 EVO 4x 500Gb, 2x 250Gb, 1x 120Gb.
Thanks in advance!
