Problem: No sound

Things to check:

--Did you change anything immediately before the problem started?

--Is sound enabled in OS? (Where do you check this?)

 --Does the laptop have onboard sound or a separate sound card?

--Are speakers enabled? (Where do you check this?)

--Are drivers/software up-to-date? (Where do you check this?)

--Does another sound device work? (card, speakers)

Use foo to check the device. ((Foo = Ubuntu's equivalent of Windows Device Manager. Is this a legit step? Outline how to use foo to check this device.)
