No, with the new "2 threads model" boomer driver, the -S parameter is not required anymore (more precisely, the server runs in a mode called "asynchronous", that somewhat "relax" the relationship between the input and the output, since each side is now running it it's own thread.) But you should always add -R (for real-time) otherwise internal threads are not started with the correct settings. Can you try again and report if it helps? If it still not work, I'll have to wait for final Boomer and do some more test here. Stephane Letz
