Hello there, people of the interwebz !

Are those troll answers ? I have the same question, and it may be just an english phrasing error ? I don't know.
If I'm correct, what this guy wants (as it looks like what I'm searching too), is getting an mp3 sample to be played virtually through the recording input, the kind of pre-recorded bits used by some streamers on twitch, or just playing a playlist in the background. This without having to play it through your stereo, which basically is just torture for the listener.
I want this for crystal clear, fast teamplay basic informations for competitive gaming. You know, so you can just focus on the game and press maccros on your keyboard in the middle of action !
Thanks in advance !
