Hi again... I've managed to get the mixer playing via USB when setting Rivendell to 48KHz. There's a lot of noise and crackling in the sound though :-(
This still puzzles me, as a Linux Mint box works okay with this mixer, so it should be related to the driver/kernel on my box running the Broadcast CD. But why is the Soundcard detection then able to play the test sounds fine? Maybe this output can make someone guide me in the right direction: http://www.alsa-project.org/db/?f=c3a76b5692a428f73d0de9af3be27664c1084e4b Thank you and merry Christmas.
