NO PC told at all and posted to Proliant server forum
that is no PC and as such the OS is not allowed there w10 nor does it have sound chips, at all, its a server running in huge dark, no humans server farm..... so let me guess you posted to wrong forum
and never told PC model sure.
so windows sounds work in the test in control panel
yes !
the, MP3 is complex, it can be from high data rate, source
and will not play unless converted .
one thing to try is use this free app
called Audacity
https://www.audacityteam.org/
then play it or convert it
or buy a USB sound dac that can decode any sound file on earth
or learn to test you PC first
windows sounds work
then in google type
simple MP3 sound test
https://file-examples.com/index.php/sample-audio-files/sample-mp3-download/
works good above so your MP3 is no good or wrong bit rate.
if fails yours only , buy new DAC USB dongle now it plays them all
if windows sounds are dead the sound driver is missing
or on a server there is no sound chips oops. buy the DAC dongle.
if only 1 MP3 fails out of 100's find a better one or buy a DAC.
