Delta44/XP problems

I have several Delta44 cards in use in the Windows XP environment. I have two cards per enclosure. The enclosures are standard consumer dektop enclosures (not tower) I have used the Delta44 cards in a NT environment and had good results. In the XP environment I get very poor results, even though the source is good and produces a solid recording on a tape recorder. The results I am getting under XP are very noisy with a lot of hiss, low volume and pulsing popps and clicks. I am recording at very low bit depth and rate as we are recording lengthy voice files for distribution via web. I have tried at higher bit depth and rate and get the same results in a richer sounding file. We record using QuickTime java classes, but the same classes with the same card under NT produces good results. Does anyone have any insight into what might be wrong? It's been driving me crazy for weeks now. TIA for any help.
 
What drivers are you using?

I run a delta 44 under XP @ 24/88.2 no problems
 
Newest drivers for Delta, mobo, graphics card, and all onboard stuff. Disabled lan and put Delta on its own IRQ. Followed all the tips in MusicXP.net and still no luck. When it eventually does work I'll be running 2.6ms latency though! :cool:
 
Do a google for Powerstrip & see if it's your video card latency on the AGP-PCI bridge. Some video cards default to the longest latency and hog the pci bus for too long, causing dropouts while you're recording.

Also have you got the latest updates for that VIA chipset? They used to have issues with audio
 
I have the newest VIA hyperwhatdyacall drivers.

Will look up Powerstrip now.

Certain VIA chipsets are incompatible with Deltas and must run highperformance Crucial RAM in order to run. What Chipset you got???

Also, STANDARD PC MODE...its your only definitive way of getting it to work..!!!
 
I'm gonna have to agree with everyone...ha.
I had my 44 running perfect for a good year on XP. it was, though:
standard pc mode, VIA chipset with latest drivers (And, it was even a chipset which people were sketchy about it working with...ha.)...N-TRACK (then later Vegas 5)...
I also had running in it:
NOT the latest drivers, those would mess up everything...so try going back a few releases.
interet/LAN always on.
cheap NVidia card - later a Radeon 9200...both worked fine.
Firewire card.

also, the main problems I figured out having during all this...was bad ram - try running some memory tests (microsoft has a memory diagnostic you run at startup...it's worth a try).
 
My chipset is the KT600. Running cheapish ram, 512mb DDR400. Really don't want to have to replace that!

What is standard PC mode? What does it change?

Standard PC mode is the earlier kind of IRQ and Resource sharing mode used in Windows98!!! Now days under Windows XP and with newer motherboards use Suport APIC which allows your PC to take advantage of the vastly improved Resource allocation proceedures...However, you can still use STANDARD PC mode if you have an newer motherboard..

Your motherboard is quite new if running that chipset...You shouldn't need to run in Standard PC mode, however, if it isn't working then its a well known way on Audio PC's to fix soundcard problems... Check out how to get it done here http://www.musicxp.net/installing_xp.php

I would say its probably an Memory issue... try disabling any Memory Acceleration in your BIOS and even reducing the CLOCK speed of your memory....Find out what latency your memory is.... Even if its branded at 2.5CAS perhaps you should try running it at 3CAS just to make sure your cheaper RAM isn't over extending itself...

Try searching the web or AMD forums on your CHIPSET and see what other people have done to overcome Memory Issues...

As mentioned above, even tho certain hardware specs sometimes are incompatible you can eventually get it working trying different things...you might not be able to overclock your PC and might loose some performance, but for music apps, who cares, you want it to run stable!!! Its not a gamming machine!!! if you wanna run games or surf the www make it a DUAL BOOT....

With respect, I seriously doubt that it's a memory or clock problem. The fact that it works at all, and that there are no other problems with the PC (right?) indicates otherwise. Memory/processor/motherboard issues almost always manifest as unexplained BSODs, freezing, failure to load, etc., across many areas of the system.

I would go back over your setup and make sure that a) your external setup is free of problems, b) your drivers are the right ones for the card and OS, and c) that the settings for the card are correct.
 
yeah, i would emphisize uninstalling all delta drivers as completely as possible, and putting an older driver version on your computer. it worked for me.
 
I think I might try putting Win98 on a new drive and using the CDs that came with my parts. Never had any trouble until I moved the Delta to a WinXP setup.
