USB mic only partly operative

My Logitech USB webcam microphone works with the command

arecord --format=dat --duration=15 text.wav

but nothing else.
Without the --format, or on the internet it lights up but does not accept sound input.
I'm using a Dell Optiplex desktop with a limited install of Wayland, Sway, and some Gnome software.
I want to use only configuration files for a simple setup.
It has HDMI output from its single sound card (device 3 for HDMI output), and I used the code on the Archlinux Wiki page 'troubleshooting alsa' to identify the USB microphone which I put into ~/.asoundrc .

/etc/modprobe.d/alsa-base.conf

options snd_hda_intel index=0
options snd_usb_audio index=1

~/.asoundrc

pcm.usb
{
    type hw
    card C170
}

pcm.!default
{
    type asym
    playback.pcm
    {
        type plug
        slave.pcm "dmix"
    }
    capture.pcm
    {
        type plug
        slave.pcm "usb"
    }
}

defaults.pcm.device 3

aplay -Ll

    Discard all samples (playback) or generate zero samples (capture)
