In this case there should be a corresponding error message from the USB controller driver in the system log; is there? It may be possible that the device doesn't handle this command because there is only one sample format/rate (but I'm just guessing here). Please show the contents of /proc/asound/card0/stream0 and the output of "lsusb -v" for the XStation. > The same thing happens when i try with 'aplay -D default'. > But with 'aplay -D "hw:0,0"' the error is: > aplay: set_params:805: Sample format non available > > Why should the error be any different?

"default" is defined as "plug:hw:0,0", i.e., the same as your "novation" definition. > From http://www.alsa-project.org/alsa-doc/doc-php/asoundrc.php?module=Generic: > "The keyword default is defined in the ALSA lib api and will > always access hw:0,0" This sentence is technically correct -- "default" does access hw:0,0 after the conversions are done. :-) Best regards, Clemens
