Post the output of

pactl list

AFAIK, pulseaudio don't touch those playback volume/switches of sources in
capture source control (mic playback volume, line in playback volume,....

control.64 {
                iface MIXER
                name 'Capture Source'
                value.0 Mic
                value.1 Mic
                comment {
                        access 'read write'
                        type ENUMERATED
                        count 2
                        item.0 Mic
                        item.1 CD

                        item.4 Line
                        item.5 Mix
                        item.6 'Mix Mono'
                        item.7 Phone
                }
        }

pulseaudio only  implement a few source in capture source control of ac97
codec and the existing algorithm does not save and restore the selected
source of capture control of ac97 codec at shutdown or startup of
pulseaudio server

This mean capture source is always  the default value of record select
register of ac97 codec after codec reset

Do pactl can select the capture source?
