UDMA introduces hard drive access noise to sound card. HELP!
I got some benchmark results for my Geforce 3 system over here: 22.50: 5475 23.10: 5845 23.11: 6117 System: T-Bird 1.2GHz, GF3, 512MB RAM, WinXP Prof. .

Hello:
Recently purchased an NVIDIA Personal Cinema PVR, and
hard drive access and mouse movements are being recorded through the line input. If I turn off DMA mode and switch to PIO 4 mode, the noise goes away. The noise is actually quite obnoxious, and I'd like to get rid of it if possible. Obviously, PIO 4 is not quite fast enough for recording multimedia. Previously, I had a AverTV stereo PVR, and the same thing happened...hard drive noise introduced into the sound card through the line input. I bought the NVIDIA system because I thought that because
the tuner is outboard, it would be less vunerable to noise. Wrong.
Any ideas? Another hint? When I install CPUidle, the sound is twice as bad.
Thanks,
CF

What motherboard chipset do you have?
Firstly make sure you have latest drivers for everything.
If it's VIA try loading the latest 4in1's and disabling "Delayed Transaction" on the Bios advanced chipset menu.
Also try moving any PCI cards out of the one next to the AGP slot.
Finally try the Via latency patch:

Hi Chicken:
Thanks for replying! I think disabling that delay transaction in the bios
may have helped significantly. The latency patch really hosed the sound!!!
Made it squeal and sqwak. :-)
I have an AMD Athlon XP 1700 ESC K7VZA motherboard, an a 1373
chip based Creative PCI 128 sound card.
Thanks for the advice,
CF
