Good news: Fix for nForce4 + X2 + 2xUAD-1

[franYo]

However, during the process I disabled my Delta1010 by adding a filter. This forced it to the AC'97 chip on the Mobo for sound. GUESS WHAT!!!! No garbled output from the UAD-1s.

That's because the onboard audio chip is a part of NF4 chipset, it's not hooked to the PCI bus. Using onboard audio the UADs have the PCI bus to themselves. Similar to using a FW audio card on a PCI-e FW card, or a PCI-e audio card, if there were any available.

Hooking S/PDIF Out on your mobo to S/PDIF In on your Delta (I assume it does have one), and using ASIO4ALL driver on top of the onboard audio chip would be a decent workaround for mixing. Of course you lose the Delta's I/O this way, so it's no good for recording.

UAD-1/intfiltr.exe update: I have tested this fix on several of my previously recorded sessions. Any large session, I still get the errors & the session stops playing. On session's with 4 or less tracks as long as I lower the playback buffer size to 256 samples or less my UAD-1 card works fine. Granted that when I used the UAD-1 on a P4 single processor unit, the UAD-1 would work flawlessly on any & all tracks. The current performance on my dual core system is dissapointing, but some UAD-1 is MUCH Better than none. I grown very partial to the EX-1, Pultec EQ's, 1176LN, LA2A, & Fairchild. I use one or more of them on everything I do......
I'm using ver 2 of the Fxpansion VST2RTAS wrapper.

i just tried the proposed fix with the UAD-1 card by limiting the card to the use of one CPU , using the Interrupt Affinity Tool. I also made sure only to filter the DSP card driver - not the Plugin driver. what happens is when I apply tthe filter to the DSP card after restart the entry for the UAD Plugin driver in the affinity tool is gone. in SX and Wavelab the plugins show but are inactive. i played around with various combinations between the DSP and the Plugin drivers. nothing works.
i had to revert to my old hardware (ASUS P4 Delux/P4 2.6GHz)
my new rig:
ASUS A8N Premium/AMD X2 4400/2GbRAM/

anyone a solution? javascript:emoticon('')
Crying or Very sad

With big help of UA support, my system finaly working fine!
Read carefully this message, and try that!
Your life will be changing!

One of our users reports that he has been able to get UAD to work with nForce 4 and an X2 processor. We have not confirmed this fix yet, but here is what he had to say:

Actually the whole issue boils down to how the way the UAD hardware
driver functions in a multi cpu environment.
The fix I used is to limit the interrupt to one cpu by telling the
kernel it to route the right way.
http://support.microsoft.com/default.as ... -us;252867
If you would allow both cpu's it goes wrong because timing issues. And
you end up getting garbled sound.
Follow the interrupt filter instructions and use it to add a filter for
the UAD dsp driver.
Reboot and enjoy a fine working system WITH the UAD.

In addition you can update the kernel for multiprocessors.

And the AMD CPU driver.

Okay. I will make this short. I am currently in a project and found that Fireface was doing \"dropouts\" when using UAD-1s and esp. when using UAD-1 GUI. (tweaking knobs and etc.) So, I guess my Neo2 wasn't working 100%. :evil:

Anyway, I ran this little tool, and found out that after setting the affinity, I lost the card. However, only thing you need to do is go into Devices, and update your UAD-1 DSP driver. Just auto update will install 4.1.0. After doing this, I was getting alot smoother UAD-1 performance. YMMV. I have to go now. Let me know what others experience.

EDIT:

0. check \"don't restart device when making changes\"
1. add filter
2. set mask (choose CPU0)
3. do this for all UAD-1 DSP card
4. reboot
5. goto devices manager
6. you will see under DSP accelerators, UAD-1 cards are marked with ?
7. update driver for each card.
8. this will reinstall the driver.

EDIT2:

NOT WORKING HERE!!!!! Ignore this post.

My system

My working configuration is:

Athlon 64 3800+ X2
MSI K8N Neo 4 Platinum
RME Multiface
2x UAD-1
1x TC Powercore mk2

Nothing of described problems I had not!
Maybe system need fresh instalation?

5. goto devices manager
6. you will see under DSP accelerators, UAD-1 cards are marked with ?
7. update driver for each card.
8. this will reinstall the driver.

well creepin crud....I should have known to go check there. I won't be able to look at this for a few days. I assumed the system restart would update the driver state. Oh well, that's what I get for assuming.

 

[ed_mcg]

h4nc0, Thank for this:

0. check \"don't restart device when making changes\"
1. add filter
2. set mask (choose CPU0)
3. do this for all UAD-1 DSP card
4. reboot
5. goto devices manager
6. you will see under DSP accelerators, UAD-1 cards are marked with ?
7. update driver for each card.
8. this will reinstall the driver.

The only thing is the dev mgr approach didn't work, I had to change steps 6-8 with a simple re-install (run setup) of the UAD package.

I've found that I can run at lower latencies down from 512 to 196 without getting the cruft.

My platform: Asus A8V w AMD 4400+ X2 with Sonar 5.0.1. I'm interested in whether this will also resolve the err=21 issues; we'll see.

 

[sj_digriz]

by the way, has anyone messed with WHICH CPU is better to use? I was setting one to CPU 0 and the other to CPU 1. Of course they were disabled so I have no testing.

Did you set both to CPU 1? etc...

 

[fuse]

The person who was mentioned would be me.

I wrote down those tools you can use to fix the problem.
For this I've used a Gigabyte GA-K8NF-9(rev1) motherboard.
Flashed the latest available BIOS to get the card to be recognized.
And I use the multi cpu ACPI OS kernel.

Actually a friend helped me with the pointer to the IntFltr tool and the link to the AMD patch. The IntFltr can be for 2000 or 2003 because XP basicly is NT 5.1 with a fancy GUI. They didn't change that much about the driver side anyway. (which is ashame really since windows isn't that well suited for professional audio like eg OSX, but they will improve this with Vista)

But please bare in mind that this is only a workaround for problems caused by AMD X2 processors and the way the microsoft multi cpu kernel operate.
There have been numerous issues with this hardware and it depends on types of motherboards, cpu revisions and of course BIOS versions.
UAD might be able to help by try to fix that workaround in their driver when it comes to interrupt support. (If that possibility is provided by the microsoft libraries)

It has nothing much to do with UA since this problem is way too specific. And motherboard manufacturers are known for their rapid (and sloppy) implementations. I used to be a trainee at such a corp and I could tell some really campfire horrorstories.
And there is a rev2 version of my motherboard so I figure something would be wrong with the rev1 versions.

And untill today I have only gotten once a STOP error (BSOD) meaning the hardware was acting up. So the IntFilter together with the drivers isn't 100% but still worked wonders for me.

And you might still get problems from other cards because they still can mess up the interrupt/kernel. Fixing this problem can be a tedious job and you even might end up getting no results and needing to buy another motherboard. Then again thats a relative small price to pay for a fully working system.

Mine is working!

I used the suggestions in this post and now my system is working great.

AMD X64 4200 x2 cpu
Evga nforce4 SLI motherboard
2-geforce6600 graphics cards on pci-e busses driving 3 Acer monitors
Sunix Firewire800 pci express (1) card
RME fireface plugged into the Sunix card
UAD-1 card on the regular pci buss
Sonar 5 PE
Windows XP prof

As with everyone else my UAD card was unusable when I first built this machine. Then I discovered this post. I ran the utility to apply the filter to the UAD card, then I installed the Sunix firewire card and took out my original Lacie firewire card because the Sunix uses pci-e (the little one), I reinstalled the UAD drivers and tried a project using 12 audio tracks, 4 UAD plug-ins, and a few native plug-ins. I kept the GUI's open for all the plug-ins and listened to the playback of the 3 minute 30 second song. Perfect playback, no studders, no pops.... I'm very excited!

Fix for nForce4 + X2 + 2xUAD-1 - NOT!

i tried all the suggestion since my last post. nothing works!
her my configuration:

ASUS A8N-SLI Premium
AMD 64x2 4400
2Gb RAM
3x Barracuda 400/300/200Gb SATA
RME Fireface
UAD-1 PCIx#1
t.c.Powercore PCIx-3

i discovered though that when i take out my t.c.powercore the UAD works fine! so at this stage i would say: if you use UAD + Powercore + RME Fireface: hands off AMD X2 processors and boards.

i am considering to go for an Intel D CPU and asus mb. has anyone a configuration that works?

thanx

 

[mjc4924]

Suggestion

Kamalski,
Have you tried swapping the cards to different pci busses?
I had to get my fireface off the regular pci bus by using a pci-express firewire card. That freed up the regular pci buss for just the UAD. Of course that may not resolve the issue with the Powercore sharing the pci buss with the UAD.
I see that your motherboard has a firewire port. Are you plugging the fireface directly to that motherboard port, not a pci firewire card? Also just make sure your not plugging the UAD and Powercore cards in the PCI express slots but use the regular slots.
I hope I'm not insulting your intelligence here.

 

[sj_digriz]

doing the re-install driver step does nothing but remove the filter. So, for me this is still no solution. With the filter in place the card is disabled. Any other ideas?

 

[h4nc0]

Hmm. I don't think this is working. After setting the affinity and rebooting, the drivers need to be reinstalled here, because Universal Audio UAD-1 DSP card entry in Device Manager is question-marked. After reinstalling the driver, the affinity setting will be gone. I thought it was working, but I guess not. Any idea?

sj_digriz,

Yes, I just found out. DOH. It could have been my unitor8 that was causing the weird problem. Not uad-1s. Anyway let me know if someone can help us get this properly working.

 

[zlatan]

I have it working !!
8)

Fresh install of XP Lite with Nuendo 3.2 and the UAD-1 plugs...

I messed up my demo period for this so I couldnt check with the other plugs but the main plugs work fine 10 + running smooth !!

the interrupt filter WORKS !!


- set filter to uad card
- set mask to cpu 0
- restart
- update driver of uad card in device manager
- enable \"don't restart...\" box
- set filter to uad card ....THE MASK IS ALREADY ON IT !

Don't restart but start your HOST ...this time the plugs should work !!

Everytime you start up you have to update the uad driver and set the filter ! The mask STAYS !! So don't touch that !

Hope this works for y'all !!!




AMD X2 4800+/ASUS A8N SLI Premium/7800 gtx/3x 1GB RAM /4x SATA / PreSonus Firebox/ Uad-1

 

[h4nc0]

Okay. This is how I got this properly set....? I guess.

1. check don't restart ....
2. set filter
3. set mask
4. restart
5. run intfiltr.reg flie

 

[fuse]

With the new 4.2 drivers even the intfilter utility won't help me no more.
I get random clicks when I use UAD plugins. Especially RE201.
Not the stuttering ones but tiny massive spikes.
And even garbled sound every then.
Rendering works just find though.

 

[A1ex]

I also had problems with the UAD DSP card driver uninstalling after reboot. Reinstalling the driver removes the filter (since it goes back to standard config settings).

I found the solution (at least for me) is to copy the intfiltr.sys into the windows\\system32\\drivers directory. Also make sure the intfiltr.reg file is loaded into the registry prior to installing the filter. (This info seems to be in the original W2k tool, but not the Server 2003 Resource Kit.)

After copying the intfiltr.sys file to the correct location, you should find that on reboots the UAD-1 DSP card driver does not become disabled anymore and the upper filter is still there.

Popping and crackling is still occasionally there for me under Wavelab/ Nuendo, but it is much reduced with the filter in place. As was noted earlier, sending audio through the motherboard's built in sound chip (non-ASIO) has no crackles at all, so there really should be some kind of permanent fix from UA for this. (Shame on UA if they don't!)

System:
MSI 7025 K8N Neo2 Platinum (1.C beta bios)
2GB Ram
Geforce 6800 agp dual dvi
UAD-1 (one card) v4.2 drivers
PoCo FW
RME 9632
(upgraded from perfectly-running single core CPU to dual core 3800)

 

[A1ex]

Update: My Neo2 seems to work finally!

Turning DMATurbo back on in the registry seems to have fixed my last few little crackles!


FYI:

[HKEY_LOCAL_MACHINE\\SOFTWARE\\Universal Audio\\Powered Plugins\\UAD HypTopo]

DmaTurbo = 1
DmaMode = 0

I guess I take back 90% of my permanent fix comment about UA, but they really could make it *slightly* easier on the end users.

 

[Daniel001]

I am crying!

This weekend I bought a Intel D940 3.2Ghz with Abit Aw-8 mobo and a second UAD-1. Because the combo intel processor + intel chipset had to work (before I wanted to buy a AMD X2). Well, my new computer won't boot with a UAD inside. Now I come here for a solution and I am reading that there is a solution for the AMD X2!!!



Can someone shoot me!?
Or help me getting this system to work...
