I didn't see anything unusual in the log. It's strange if switching the profile
is required. The source will suspend itself after being idle for a while, and
I'd expect that to reset the kernel driver or the hardware equally well as a
profile switch. Running pavucontrol prevents the source from suspending, but
the log showed that the source was idle for long enough to suspend before you
opened pavucontrol. So at least one suspension isn't enough.

Could you try the following:

After a reboot, check that the microphone is suspended with this command:

    pactl list sources short | grep usb

At the end of the line it should say SUSPENDED. If it says RUNNING or IDLE,
wait for a few seconds and run the command again. If it's not changing to
SUSPENDED, something is keeping the microphone open. Don't run pavucontrol,
since it will keep all devices open all the time.

When you've checked that the microphone is suspended, record some audio from it
with this command:

    parecord --device=alsa_input.usb-046d_0802_033D4660-02.analog-mono test.wav

Does that work? Is the audio ok? If it doesn't work, wait until the microphone
is suspended again and try again. Repeat this a couple of times. If it doesn't
start to work, then clearly suspending is not sufficient. Then try these
commands:

    pactl set-card-profile alsa_card.usb-046d_0802_033D4660-02 off
    pactl set-card-profile alsa_card.usb-046d_0802_033D4660-02
input:analog-mono

That should have the same effect as changing the profile in pavucontrol. Does
recording audio with parecord now work?
