Turtle Beach Santa Cruz audio fades during capture?
 

Hi all,

After a long hiatus I have started capturing again. For some background I'm capturing VHS tapes using the following equipment:

• JVC SR-V10U S-VHS VCR

• Panasonic DMR-ES15 DVD Recorder as a pass-through pseudo line TBC

A custom built Windows XP capture PC with the following hardware:

• ASRock 775i65g r3.0 Motherboard

• Intel® Core™2 Extreme X6800 CPU

• 2GB Corsair XMS DDR RAM

• ATI All in Wonder 9200 GPU

• Turtle Beach Santa Cruz Sound Card

• 500GB 7200RPM HDD [OS]

• 1TB 7200RPM HDD [Capture Footage]

• 2TB 7200RPM HDD [Capture Footage]

I've been experiencing a frequent issue with audio levels during capture. Within the first 10 minutes of a capture in VirtualDub, the left audio channel slowly fades away to a point where it is inaudible. The levels seem to improve somewhat when I run the Turtle Beach Sound Card utility, but this fix does not last. Does anyone have advice as to how I can prevent this problem from happening? Thanks.
