External audio device shows up in the sound output options but the sound
keeps being emitted from the internal laptop speaker, or none at all.

Title:
Sound applet won't change output device
Status in gnome-control-center package in Ubuntu:
New
Bug description:
Using the gnome-control-centre sound applet to change the output
device from the motherboard's default to an external USB device used
to work well on 19.10, but does not work on 20.04 Beta.
I use a USB headphone DAC/amp on my desktop (Schiit Modi/Magni combo).
Under Ubuntu 19.10 I could use the sound applet in the gnome-control-
center to select either that USB device or basic audio through the
HDMI cable on my monitor (it would always default to the basic audio
on reboot, but that's another story) then use my headphones happily.
Using Ubuntu 20.04 Beta the sound applet shows all of the expected
devices, but choosing different devices has no effect - any music then
played continues to come only from the monitor. Using the 'Test'
button plays sound only through the monitor also.

In case this is useful at all, I've playing around on the command
prompt::
$ pactl list sinks short
0 alsa_output.pci-0000_03_00.1.hdmi-stereo-extra3\
module-alsa-card.c s16le 2ch 44100Hz SUSPENDED
1 alsa_output.usb-Schiit_Schiit_USB_Audio_Device-00.iec958-stereo\
module-alsa-card.c s16le 2ch 44100Hz SUSPENDED
$ pacmd set-default-sink 1
$ paplay Chicken\ Cluck.wav # Headphone output working!
$ pacmd set-default-sink 0
$ paplay Chicken\ Cluck.wav # Monitor output
Unfortunately, the command that let me listen to chickens on my
headphones (pacmd set-default-sink 1) had no effect on sounds from the
rest of the system (mpv and Rhythmbox tested).
