Hi,

my Fireface 800 is connected to either the Firewire 400 port or a Lacie PCIe Card via FW 800.
Both are TI.

I wanted to give Firewire legacy driver a try and looked them up where they're suppose to be,
but there's only a "Texas Instruments OHCI Compliant IEEE..." and a "OHCI Compliant IEEE..."
to choose from.
No Legacy driver in Vista32?

I want to revive that 5 year old notebook for mobile recording since it features PCI express, Firewire and TI chipsets.

I experience crackles and short drop outs, especially when moving windows around the screen,
changing their size, or when visual changes take place on screen.
Like jumping song pages in my DAW (Nuendo) or during tracking/recording, when audio waves are drawn...

My VGA Card is a Gforce 8600M GT w 512MB using the very latest driver (295.73)
The crackles and pops don't show on the CPU meter and are not recorded.
The audio waves do stay intact but the interrupted playback allows no accurate time keeping for musicians, of course.

The DPC Latency Checker shows massive red spikes at the time of a drop out, but only when the FF800 delivers sound.
When silent (but switched on and connected) the red spikes are gone.

FF800 driver are 3.0.67.0, Fut is 2.77.
Changing buffersize has no effect.

WiFi, internal sound and everything not recording- or system related has been removed or deactivated.

My Fireface 800 appears to be old (from 2004) but in perfect good health.

Thank you all for your kind input and braintime.

Erbs
