On the archlinux sound troubleshooting wiki ("The only device
shown is 'dummy output'..." section), they suggest
executing

  fuser -v /dev/snd/*

"to see which application is responsible for a direct access to the
sound card via alsa," and then perhaps closing that or those apps in
order to give pulseaudio precedence.

https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting#The_only_device_shown_is_.22dummy_output.22_or_newly_connected_cards_are_not_detected

Maybe worth a shot.
