I'm looking for an OmniStudio USB (see other message). But it doesn't have S/PDIF. I think I can add the ESI WaveTerminal U24 : http://www.esi-pro.com/viewProduct.php?pid=10&page=1 I see 3 WaveTerminal on http://www.alsa-project.org/alsa-doc/index.php3?vendor=vendor-Ego_Sys#matrix Do you know if it works with Linux? (Debian) Thank you. -- sigir
