Hello, for those of you not subscribed to LAD, I finally got to write a mixer application for the EMU 1010 based cards. I tossed out the original ideas of a full-featured app and went the simple way, just basic point-to-point routing, no fancy "Multichannel" features. It's available here: http://code.google.com/p/emutrix/ Screenshot: http://www2.udec.cl/~cpolymeris/emutrix/Screenshot-EMutrix-1.png Be aware that the code is awful, just fast prototyping, but functional. It may also mess with your mixer levels, if you want to try it. please make a backup with 'alsactl store'.
