HP Pavillion 1723w - sound does not work properly

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

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.

Does this happen when you play a CD disc?

most system has seperate audio ports for the speaker and the headphone but they are interchangeable. try plugging the speaker on the audio your using for the headphone. if your already using the same audio jack then try using another speaker, but since you mentioned that the headphone works then its possible you might need to replace your speaker

Try to uninstall and install a new copy of the sound driver.
if it's not working maybe that you need a new sound card because somtime the integrated sound of the motherboard stop working

good luck;)

you have to send it back to hp to get it fixed, this is the second time mine had the same problem

Just unscrew, remove the entire CD ROM, fix the RAM properly and while connecting the CD ROM ensure that all connections are snug tight...sodeep

just installed the motherboard cd of your hp pavillion

Whenever you try to play music or any other audio you get a message that your hardware is malfunctioning or not found then you may have problems with your Sound drivers try downloading new drivers or installing from your driver cd or dvd if you have one. you cn download the sound drivers from www.hp.com.
