LF: A second soundcard

["John RABSON" <john.rabson@wanadoo.fr>]

I have a HP Pavilion Media Center a1620.fr Desktop PC running XP. I would like 
to use it to decode QRSS and other signals.  The existing soundcard is used for 
dictation (and it doesn't seem to have a line input, only microphone). 

HP tell me that I cannot have two soundcards running at once in this computer.  
They say I can have two soundcards installed, but whenever I am using one, the 
other must be inactive.

Has anyone any comments, please?
