Marvel G200-TV audio recording is distorted when recording video to an ATA66 Hard Drive connected to a Promise Ultra66 PCI IDE controller with audio quality set to 44kHz stereo.
When I record video with audio quality set to CD-quality (44 kHz stereo), the sound is garbled and has ticks and pops. If I remove my Promise Ultra66 controller and connect the hard drive to the onboard ATA33 IDE controller, the sound records fine, but the video has dropped frames (when recording highest quality video). I have tested the Promise Ultra66 controller and it appears to be working perfectly (other than this problem).
My system configuration is as follows:
MB: FIC PA2013 rev. 2.0 w/ VIA Apollo MVP3 chipset, 100 MHz FSB, 2 MB Cache, Socket7
CPU: AMD K6-2 400 MHz
BIOS: Award (date: 06/99)
OS: Windows 95 OSR2 (with latest updates)
Sound: Diamond Monster MX300 PCI
HD: Western Digital Expert 18GB, 7200 RPM, 2 MB cache, ATA66
Video: Matrox Marvel G200-TV AGP
Video Drivers: beta 5.15
Video Tools: beta 1.5
Marvel G200-TV BIOS: 1.6-20
Software: Avid Cinema 1.0 for Marvel G200-TV
IRQ: Marvel G200 at IRQ5. There are no IRQ conflicts.
I tried Matrox video driver 4.33 with video tools 1.21 and still had the same audio recording problem. I tried Avid Cinema'a audio patch, but still had the problem. Since I observe the problem with both the Avid Cinema and the Matrox Video Tools, I do not believe that the problem is software specific. I would settle for recording at TV-quality audio since the problem is not noticeable at this audio quality, but the Avid Cinema software uses QuickTime 3.0 and records audio only at 44kHz stereo.
Any suggestions?
