from the presonus site. have you read this ?
https://support.presonus.com/hc/en-us/articles/210044653-AudioBox-Family-Record-and-Playback-troubleshooting-

in those advanced tabs note you have 48khz selected.
might not make a diff but change to 44.1khz 16 bit.
also see levels tabs, check to see those levels are up ?
(sometimes one has to experiment.)

if your not getting playback outside of ptraks...
eg are you able to play a song back from you tube ?
then somethings muted somewhere obviously.
are you sure you dont have something muted in audio box ?

if this cant be solved , you might have to try another interface. but...for now forget ptraks ...
lets focus on you not getting regular windows media player playback. therein prolly lies the solution.
keep your chin up ! i'm curious to see what simon says.
but try advanced tabs 44.1 16 bit and set everything as a test to that.
best
