[LAU] RME HDSPe AIO, hdsploader compulsory ?

Hi All, I'm new to this list (and to Linux too... although heavily used to old DOS commands) I have fitted this card from a Windows PC into a Lubuntu PC (latest build). It looks as if the card is well recognized ("RME AIO card found" when launching hdspmixer for example), I guess it does not work due to a routing issue. I have 2 questions : 1 - is it compulsory to use hdsploader, even if the card is recognized ? 2 - as there is no Matrix in Alsa as there is in Totalmix under Windows, am I right assuming the only way to do the routing is to use amixer commands like : amixer -c 0 cset numid=5 source,output,0 (my card id is 0 as I deactivated the MB sound card) ? Thank you for the help ! -- francois juigner <francois.juigner(a)bluewin.ch>
