Low Latency Delta 1010L Fizzling sound

I have two PCI-cards in my system,

A M-Audio Audiophile 24/96 and a Delta 1010LT card
They use the same driver.

When running buffers lower than 256 bytes, e.g. 128 or 64 bytes
there sometimes appear a fizzling almost alias-like distortion that
appears vaguely and then dissappears.

My QuadCore system is not especially loaded and there are no regular
dropouts either. Just this slight fizzling sound which sometimes appears.

Is this something anybode else has experience with?

Best regards,
Mattias

I think I solved it.

I guessed that the driver had problem soft-syncing the cards, so I took
an RCA cable and interconnected the SPDIF-inputs and set one card
with external sync.

Now it works like a charm. I run with 64 bytes buffer and no noise!!
