Re: [Trisquel-users] Sound doesn't work. How to identify and lose the problem ?

The point about booting it from a Mint Live disc is that you might find that  
the sound works and/or that you can add the wireless device. (Note - I  
suggest using a live disk rather than installing).
Non-functioning hardware might be faulty hardware, it also might be that the  
hardware needs some non-free stuff in order to work properly. Thus, the best  
way to test this is to use a distro that includes the non-free stuff.
At least you then know where you stand and can make a more informed decision  
as to how to proceed.
