Audio output device changes unbidden under f34

[Jonathan Ryshpan]

When I queue up a number of podcasts to play in rhythmbox, the output
device often changes when the second podcast starts, from a device
connected via a USB port to the built in audio.  This happens when I
use either the PulseAudio Volume Control application or the KDE Plasma
Audio Volume applet.  I don't remember it happening under Fedora-33.

System
 * KDE Frameworks 5.83.0
 * Fedora-34 with all updates installed

Just to be thorough:  Can you plug it into another USB port?

If the connector is a bit loose, the device could be intermittently
interrupted and resetting.  Perhaps sometimes it recovers, sometimes it
doesn't.

A very good point.  I'll try different ports over the next few days.

But service should continue to my desired (USB) device since it's
selected as the default in the KDE Plasma Audio Volume applet, using
   Applet->Device->Digital Output->Play all audio via this device
Digital Output is the desired device.
