[Dx4win] second sound card

[Tony Lord]

I am wanting to try these digital modes after years on SSB/CW! I have
some new software which recommends using a second sound card, just for
this software. I brought one and installed it on my PC (Compaq P4,
1700MHz, Op System XP). XP automatically installs the necessary drivers
but then deletes the onboard sound card  (built into the mother board).
Does anyone know how I can install this second card and still keep the
first sound card active?? (By the way when I remove the new sound card,
XP reinstalls the on board (first) audio card).
