Hello James,

This is my very first time experience with OpenOB.

I have set up 2 old IBM P4 HT 3Ghz desktops running Wheezy and installed
OpenOB on both.
They are running OpenOB on the onboard sound cards through ALSA over a
100Mbit fast ethernet.

Using 96kbps Opus I get 390ms of delay, and using PCM 360ms, far above the
mentioned 50ms, what am I doing wrong?

Thanks for building such usefull software! Congratulations,
