I have been trying to troubleshoot a linux system similar to my system with FC3 and rhfc3.ccrma that is having sound problems. The system with the problem have two sound cards: CA0106 (card0) and EMU10k1 (card1). Among other mysteries, I am particularly stumped trying to determine what conflict exists when: 1) aumix: no device found 2) aumix -d /dev/mixer -q : no device found (when /dev/mixer exist) 3) alsamixer -c0: there is no MIC 4) there truly seems to be a misconfiguration somewhere which points the pcm devices of the sound cards i.e. audio output directed to card1 (/dev/dsp1) is actually delivered to card0. Below is output from aadebug. Any pointers will greatly be appreciated.
