We could try disabling the mic that is not working, although that would feel a little like partial failure, it would still be better than current state.

To try this, first make sure no audio applications are running, including pulseaudio:

echo autospawn = no >> ~/.pulse/client.conf
killall pulseaudio

Here are the commands to perform the change:
sudo -s
echo 0x0b 0x4f0000f0 > /sys/class/sound/hwC0D0/user_pin_configs
echo 1 > /sys/class/sound/hwC0D0/reconfig

to restart pulseaudio afterwards, delete ~/.pulse/client.conf - then start your recording program and retry.

As for 'Input Source 1' btw, that's connected to a separate ADC input channel that's not usually used.
