I also tried setting a slightly higher latency (like 5 ms) but it doesn't matter. I checked the source code, and latency_msec is missing from the list of valid module arguments.

Actually, I can't seem to get a good latency so I will try some other solution. MvH Tor-bj?rn -------------- next part -------------- An HTML attachment was scrubbed...
