Public bug reported:

When on-board headphones via the 3.5mm jack is selected as the output
source, listed as "Headphones - Lunar Lake-M HD Audio Controller", sound
from media will begin playing via the on-board speakers before switching
to the headphones.

When this occurs, a volume bar appears on the screen.

This occurs more frequently when media has been stopped for at least a
few seconds.
