no sound toshiba laptop

now its going away and coming back and then disappearing again.. oh well (i managed to get it going by messing around with code lines in terminal then shut it off and when restarted it dont show any devices in sound

i guess i gotta type billions of other code lines and keep testing every option any way to get fast response???

ok it seems i have found a temp fix and maybe some of the cause but it would be alot easier if i had a human to explain as it to much info however when i remove and reinstall the pulse audio via software then sound is somehow now restored yay finally i found a fix but its really useless i dont know how to find the config file and most commands i type dont work telling no file or command so ye i guess im really new at this..

What is the output of:

wget -O alsa-info.sh http://www.alsa-project.org/alsa-info.sh && chmod +x ./alsa-info.sh && ./alsa-info.sh

Thanks
