After updating to minecraft upgrading to 1.1.5, no more sound

After updating to Minecraft upgrading to 1.1.5, no more sound.
here is what I had done:
1- uninstalled and reinstalled the game - didn't work
2- load an old / new world, press "F3 + S" - didn't work
3- load an old / new world, press "F3 + T" - didn't work
4- changed another sound card - didn't work
5- update my windows 10 to the latest windows updates. - didn't work
note that all the sound for other games, youtube all have no issue with sound.
Please help if anyone have a fix for this issue?
thank you.
