No sound even though it was working fine yesterday RRS feed

  • Question

  • Hello everyone!
    I'm having a big trouble with my windows 8. Yesterday I was watching a clip on YT and suddenly the sound stopped. I tried to restart the computer. I didn't work. The sound on YT is on full voulume as well as on my computer. Then I went to sound configurations. I clikc 'configure my speakers' and 'configure' then 'test' and I get a message that 'the sound can't be played'. I tried playing some music which is on my computer instead of playing music online and windows player says 'windows media player had found a trouble wile trying to play music'. I downloaded winamp but it didn't work as well. What is more I was sometimes using Ubuntu via Virtual Machine and the sound had been playing ok but when I tried to play sth today it was silent... Of course I googled the problem up and read what Microsoft says I should do in this situation (check the sound card, ect. I did it, downloaded the program attached to the tutorial and the program found no errors). The issue can't be due to reinstalling my system - my computer is one week old, it was bought brand new it has never fallen down or anything. One more thing. Yesterday out of blue moon I started getting errors while starting the computer. The errors are: "Changelcon MFC Application has stopped working", "persistence Module has stopped working", "an error had occured while starting c:\program files(x86)\intel\bluetooth\btmshellexe.dll".

    I really need your help guys, I have no idea what to do and my finals are approching and I'm in need of sound on my computer so that I can watch lectures and tutorials... So please, help me somebody?
