In the case where we have both line out and more than stereo speakers, the speaker DACs will end up in extra_out_nid. In fact, AFAIU, speakers are the only ones that can end up in extra_out_nid, and if we have several of those, they should be surround outputs rather than copy front.

Specifically, turning the pulseaudio volume upwards only changes the 'master' and belatedly the 'pcm' volumes inside alsamixer. This ignores 'speaker clfe' + 'speaker front' + 'speaker surround playback volume' plus maybe others. Effectively, this means audio playback is weak: instead of spreading typical 2ch audiofiles across all internal speakers, only some are used, and only at whatever volume alsamixer specifies. (Turning the ignored volumes up in alsamixer causes a different problem: then it is no longer possible to lower the sound to a relatively-quiet volume.) Here is some information from one of the ubuntu pulseaudio/alsa devs: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/946232/comments/159 David Henningsson ([email protected]) wrote: ...you have unusual hardware: in addition to normal headphones and stereo line out, you have 5.1 internal speakers. This leads to unusual alsamixer names (e g "Speaker Front") which we do not match for in PulseAudio. Fixing that means that we should add those names in PulseAudio - but let's discuss that in a new bug instead. Let me know if you would like more specifics.
