Yeah, it's what I thought, but then, as said, I tried the planetccrma
kernel and drivers, which are supposed to support professional audio
applications. Not much difference, unfortunately. I even tuned pci
latencies to no avail.

My card btw is a soundblaster with ensoniq chip, so any obvious driver
anomaly presumably would soon be filed as a bug, Fedora Core or
otherwise. But, with alsa oss emulation and stuff, it really might be
that latencies just add up, which would after all mean that Linux as a
desktop system still has it's drawbacks.

Anyway, in case you use softphones on Linux, and did compare their
performance with Windows alternatives finding that they can compete, may
I ask what card/driver/kernel version do work for you?

Thanks, Bruno.
