It turns out that the information in my Asus mobo manual is wrong (imagine that. I just got an HDSPe RayDAT card - my first RME gear - and installed it into my rig and ran into some issues with clicks and pops testing playback and some tracking in Reaper at 192KHz sample rate and found this post researching the crackles/pops. Sorry to sort of "dredge this up" again after several months but it seemed the best place to ask.įirst of all thank you christianwn for posting this. You can do this with lots of devices, do be careful with your system while tweaking. This is the cure to our problems with irq sharing, that still exist today. So I tried to put the FireWire controller in MSI mode and it started up, but the UCX was not detected by the RME drivers, I wonder if this can be fixed, because it seamed that the FireWire card was detected without any errors by windows. Started Latency Monitor because it can produce pops and clicks sometimes, same result, perfect audio! Started Firefox with lots of tabs while playing guitar through the DAW just to be nasty to the system, still no pops or clicks.
Reboot and test, BINGO! Rock stable both USB and FireWire, not pops or clicks. In the link below I will share a document/link that describes the process of changing the way devices use old irq or the new MSI.įirst of NVIDIA support this and switching to MSI made irq sharing with the USB and FireWire controllers go away. Can all devices do this? No, but some can and this can have a HUGE HUGE impact on your system. This is a more modern approach to interrupts that goes beyond irq sharing. I started looking at the irq numbers, and being not young anymore, I see something new to me, negative numbered irqs, what is this? Answer: Message Signaled-Based Interrupts = MSI.
Looking at the resource list of irq sharing on this computer reveals the problem at once: The graphic card is sharing irq with both USB and FireWire controllers all on irq 16! Reading on internet, irq sharing is supposed to be "OK" and something that drivers are supposed to completely support, right. So I go thru all the old tweaks to see if something helps. Installed RME drivers for my UCX, both USB and FireWire to see if anyone gives better results.
