Behringer UMC404HD USB sound card problems

Completely new to Arch based distros. My sound card is listed in alsamixer, as well as here:

$ inxi -A
  Device-1: Intel Cannon Lake PCH cAVS driver: snd_hda_intel
  Device-2: NVIDIA TU102 High Definition Audio driver: snd_hda_intel
  Device-3: BEHRINGER GmbH UMC404HD 192k driver: snd-usb-audio type: USB
  API: ALSA v: k6.1.30-1-MANJARO status: kernel-api
  Server-1: PulseAudio v: 16.1 status: active

Unfortunately, I have only been able to get audio out once futzing around with the following:
$ alsamixer # Open in one tab and find which output is the sound card. Note number at end.

$ alsactl store # Open in second tab and run command

# nano /etc/modprobe.d/alsa.conf Open file and add the following
options snd_usb_audio index=2 Usually “0” at the end, but on Manjaro it is “2”.

No luck since then in reestablishing audio through the sound card. Also only time that the sound card appeared in the xfce4-pulseaudio-plugin.

Any help would be appreciated as I had plans of following Unfa’s configuration.

Welcome to Manjaro forum

ALSA commands can use an alias name instead of the card number
e.g. to check ALSA audio controls:

alsamixer --card=U192k


amixer --card=U192k

The card name can also be used when configuring JACK - hw:U192k,0 instead of hw:2,0
so JACK can use the USB interface with any card number assigned in ALSA

How do I refer to a soundcard so that the name always works? | JACK Audio Connection Kit
