Bug description:
[Impact]
On the Dell AIO machines, there is no internal mic, after plugging a
headset, users expect the headset-mic or headphone-mic could be selected
automatically. But with the current rule, the headset-mic/headphone-mic will
not be selected automatically and even users manually select them, they will
not show up in the gnome sound setting, and users could not record sound by
headset-mic/headphone-mic.
[Fix]
backport a patch from pulseaudio mergerequest, the patch is going to be
merged to pulseaudio 14.1. This patch could be backported to hirsute without
any change, but need to be changed if backport it to groovy and focal.
[Test]
On those Dell AIO, plug a headset, open the gnome sound setting, the
headset-mic is selected automatically, use the headset-mic to record the sound,
the sound could be recorded and the sound quality is good.
[Where problems could occur]
This patch could change the policy of audio device switching, it will not
affect all audio devices, but only the devices which has AVAIL_UNKNOWN
available status, that means it has possibility to introduce the regression on
headphone-mic ,headset-mic, internal mic and internal speaker's switching since
they all has AVAIL_UNKNOWN status. For example, after unpluging the headset,
the input device will not switch to internal mic automatically or after unplug
the headphone, the output device will not switch to internal speaker
automatically. But this possibility is very low, we have tested the patch on
many Dell and Lenovo machines, all worked well.
