Since this is the General Discussion :
Here you can discuss every aspect of Debian. Note: not for support requests!
The general discussion board is great for general discussions, so any way,
Nice to hear you bought this new laptop , and also hope you enjoyed the trip to
the states and back.
I can't imagine why the sound does not work,..but I am sure if you browse the
forum you will see there are many topics where people have had problems with
the sound. Also if one reads some of the other posts that have been posted and
they are asking for help on a problem, the first thing you may notice is , invariably they are asked about what version of Debian they have installed, and other details about the problem, in fact reading some of the other topics on this is a good way to get some idea as to what information is needed.
Don't get mad or feel bad , this (lack of details,and information) is a very common problem, I suppose it is because so many new Debian users do not realize there are many versions of Debian, and that there is differences, so one of the most important things is to include what version one is using.
You can search the forum a few key words;
example: Search found 16884 matches: +sound
Also this: https://wiki.debian.org/SoundFAQ
Of course I realize the OP's situation is unique, and maybe none of the other solutions will apply, however , the ones that were solved should be a good example , as to what information is needed, etc.
There also is this: http://www.catb.org/esr/faqs/smart-questions.html
it gives some tips on how to ask a question, in a way that will get better answers
instead of non-answers like mine.
Welcome to the forum, and thank you.
There are several very knowledgeable members here, and they are all ways
happy to try to help, but they do need some specific details, etc . to be able to do that. I hope the OP and others understand.
