yes, this interface board will have TWO (mic and speaker out) audio cables coming off it that will need to be plugged into the computer sound card or if your computer sound card is not working then you can use a USB sound card.
Volume can be adjusted on the computer AND on the interface board that will also have "fine" tuning adjustments too!
NOTE: The volume controls that are on the interface board is ONLY for the sound coming from the repeater!! If you need to adjust the date & time, etc do that within the programs!
NOTE: I recommend getting the USB sound card!! I have a brand new (cheap) laptop and the built-in sound card is not very good for this!!
