This seems strange. But a pulseaudio verbose log could probably reveal
what is happening.

Anyway, since ALSA does not use profile availability, your patch will
unlikely affect the problem, but I guess you already figured that out.

I think you should try to debug module-switch-on-port-available, that's
probably where the problem lies. But again, a pulseaudio verbose log is
the key here I'd say. I guess if you modify default.pa to not load the
restore modules that would emulate a clean boot well enough for this
scenario.

I skimmed it through - if somebody has a "line out" port that's
unavailable but still he has something plugged into his line out, that's
a bug. Alsa-info and PA verbose log needed to figure out if it's PA or
kernel.
