Ok, I was finally able to reproduce that here by booting my old laptop and I can confirm that adding the patch in comment #18 just adds analog-output-mono, not analog-output.
I was also able to find and fix bug 932804, which can make it impossible to change port.
But; when analog-output-lfe-on-mono was selected, sound volume was perfectly changable through e g the indicator. So I'm not sure what the problem with this profile is, really?
