This section explains in, as much possible details about Modules with respect to corresponding sound card .Please refer to your sound card manuals for details regarding chip set etc .There is every possibility of a card with a high sounding name as A-Z Digi-Alive may have nothing to do with a equally high sounding card named Digi-dead A-Z ,Hi-Fi.They are basically generic names solely for the purpose of printing on the card board boxes and blurb.Also spend sometime poring over manuals distributed with card with a good quality magnifying glass ;-) ,it should help.if it still doesn't make sense ,try to find a friendly neighborhood tinkerer to help you out.
Module snd-card-dummy.o. for the dummy sound card. This sound card doesn't do any output or input, but you may use this module for any application which requires a sound card like RealPlayer.
