I have ordered XFX HD-557X-ZHF2 as per the members for my Asus CM5570. I found out the line in does not work when I used external speakers and need to change to a compatible sound card that works with XFX HD-557X-ZHF2.
Appreciate your suggestion.
I have already placed an order for ASUS Xonar Essence ST Headphone 7.1-Channel Audio Card for Audiophiles. It has a line in and I want to convert old cassette tapes to CD and also use it to listen quality audio and my son can play games.
Thanks for all the members help that responded.
