I'm wading through the comments here, let me know if I'm missing something...

Anyway, if PulseAudio is not running, don't expect this to work:

 1) the sound preferences dialog
 2) pavucontrol (naturally)
 3) A little unsure about speaker-test with "-D default". -D default means to go through pulseaudio normally, but if pulseaudio's not running, it should automatically reroute itself. To be specific you can use either "-D pulse" (always goes through pulseaudio, will complain if it's not running) or "-D plughw:PCH" (where PCH is the card name) to always bypass pulseaudio.

Sorry, the support has been discontinued of this method. I've now updated the wiki page(s) to reflect this.

The DKMS package I gave you is the better way to upgrade your ALSA drivers. The patch I sent was applied upstreamed yesterday, so automatic DKMS builds will pick this up from today too.

Not really. I've brought it up for some quick discussion upstream a while ago but I don't think it went anywhere.

Anyway, with my suggested patch to the pulseaudio conf files (that adds "Speaker Front" etc sections), you should no longer need any workaround from bug 946232. Sorry if this was not clear.

Raymond seems very much into analyzing why the driver doesn't currently support external 7.1, and he's posting his thoughts about why. I'm more into trying to get your 5.1 internal speakers up and running because that's the problem you ask about.

So, given that your system has
 * DKMS package with latest driver installed (the one I gave you) and
 * PulseAudio patch for "Speaker Front"

...both installed, where do we stand? Everything working as it should, except the subwoofer?
