A port with the availability state flag set to unknown should not be considered an active port.

I think this will break the following use case (on a normal laptop) :

Assume we plug in HDMI. With this patch we will get inconsistent

behaviour: if headphones are plugged in (available = yes), we won't switch to HDMI, but if not (speakers are available = unknown), we will switch to HDMI.

if you look at those bug reports of no sound for those on-board ac97 codecs with ubuntu 12.04

https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1033996

how does pulseaudio determine which controls are effective in the headphone path and speaker path of those ac97 codecs ?

the analog-output-stereo profile for the line out jack is missing

( 0.056| 0.000) D: [pulseaudio] alsa-mixer.c: Removing path 'analog-output' as it is a subset of 'analog-output-headphone

is there any solution for those snd-intel8x0 and those onboard ac97 codecs with headphone playback volume control ( no ctljack control and no phantom port)?
