Welcome Jose :)
I read your whole mail to the _u s e r m a i l i n g l i s t_.
Seemingly you aren't aware what exactly Linux is. There never will be a
warranty, when using Linux the user does everything on her/his personal
responsibility. Most of us are users, some are coders, but usually
coders that don't get money for their work.
We try to help each others. If you want to get help, than try to write
shorter mails. There's no need to mention that you lost your driving
license etc., it's ok to write this, but less good when a mail already
is that long.
Some of us, e.g. me, are not good in understanding the English language,
this is an international list.
Do I understand correctly, that the sound device has to be an USB
device? Or could it be any kind of audio device?
Regards,
Ralf
