ok so i found a sorta fix to this problem i got my headphones to work altho the inbuilt speakers continue to run at the same time as the headphones and they wont turn off,im working on figuring that out,il explain what i did.
i just went to control panel,add remove programes then i uninstalled realtek HD audio driver it has a sorta blue spider beside it,after that i just restarted my computer with out replacing the audio driver,when the comp restarts it comes up with the found new hardware wizard,all u hav to do it alow it to acess the internet and hit install automatically,if it dosnt find anything the first time retry it found it on the second time for me,when it finds it it will install it automatically,and then the headphones should work but the internall speakers will continue to go,
so going buy this i think i can confirm it is most certainly not a thermal issue but a software issue something with the realtek driver,
i attatched a pic of what realtek adio manager loks like after all this
o and i checked the auto popup thing when the jack is plugged in
i just hav that speaker thing to resolve
