Hi all,
post #1;
I have a Delta 410 (PCI), bought as new-old stock about 2 year ago, it works extremely well for my purposes (mostly archiving vinyl and other analogue sources), except for SPDIF-in.
I'm been trying to use a Flying Calf ADC, and I get a lot of noise (crackling) which seems to be related to the display - any movement at all on screen, such as the cursor (mouse movement), or the level meters in an audio app. produce a corresponding incease in noise (along with the more persistent slight crackling).
Additionally there is also a rhythmic pulse of noise (every 2/3rds of a sec or so) in the resultingrecordings, as if the card isn't syncing up properly with the Calf's clock (at 44.1 or 48).
Disabling all graphics acceleration and underclocking the GFX card doesn't help, and unfortunately I have no other video-out on the PC.
The Calf has been tested in other setups and works perfectly (noise <-106dB).
The 410 is on it's own IRQ.
++++++++++++++++++++++++++++++++++++++++++++++++++ ++
Asus P4G8X / P4 skt 478 3.06GHz / 2 x 512MB crucial PC2700 RAM
Win XP Pro SP2 (ACPI enabled)
nVidia 7600GS AGP
Hauppauge Nova-T DVB PCI card
SCSI PCI card
M-audio Delta410 PCI
