Hi Paul. I'd suggest to try couple of things: 1) try to disable all other sound services, like pulseaudio(default in ubuntu)/jack/esd/etc. 2)try "alsamixer", there could be a switch somewhere which you turn, and it might enable rest of speakers. Switch's name may not necessary reflect relation to turned off speakers, thus may be misleading. 3)check whenever your sound application actually takes advantage of surround speakers(if you listen to mp3 - mp3 player will be only providing sound in stereo, so sound buffer isn't used, until some up mixing on software or hardware level is used). I believe "speaker-test" command may be of some help there. 4) if advices above didn't help perhaps ask same question in alsa developer list.
