After reading HD-Audio.html, I used the hda-analyzer to configure NIDs 0x14, 0x19 and 0x1b to become outputs, and when I execute: speaker-test -Dplug:surround51 -c6 I can hear sound on all 3 jacks, but only for Front left/right channels. In other words, all 3 jacks are being treated as Front. To confirm this, in alsamixer, the mute on Front (0x14) does mute all 3 jacks. I guess I am missing the relationship between alsamixer and the codec. How can I get aplay and speaker-test (with plug:surround51) to map to Front/Mic2/Line2, now that I have configured them as outputs?
