Hallo, sigir hat gesagt: // sigir wrote: This should work, I think (but didn't test). I tested some other devices from ESI. It looks, as if this is a generic, standard's compliant USB audio device from reading the Mac OS-X FAQ: ESI Waveterminal U2A/U24 can be used on Mac OS X without needing to install any additional driver software, thanks to Apple's excellent support for generic USB audio interfaces. This means, it uses the Mac standard driver that is intended for standard devices. Buy it! (And if you do please add some notes to the alsa wiki on alsa.opensrc.org and the alsa-project.org docs.) ciao -- Frank Barknecht _ ______footils.org__
