Troubleshooting for Laptops: Sound

This page is highly incomplete, and will be heavily edited in the coming weeks.)

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.

(What is the Ubuntu's equivalent of Windows Device Manager? How do you use it?)
