Also you might try setting the minimum/maximum playout delays to their
lowest setting under the rat Reception options and limit playout delay.
Are you running 16-kHz Mono?

I was watching a session today closely, and am seeing very tight synch
between audio and video. This is with audio on a Linux box with an
ES1370-based PCI128 card, and video on an Athlon win2k box..
I suspect again your problem is some combination of some network loss,
causing rat to increase its buffering, and the use of the SB Live, which
induces higher latency anyway due to a large fragement size.
We should do some testing online sometime, and see if others are also
seeing the badness.
