I don’t know how my Dad’s computer got this, but its an old PC with a 2003 (!!!) Realtek driver and a terrible reverb/echo. google:”Realtek reverb” revealed a very smart person “saying”:http://www.elitehackers.info/forums/archive/index.php/t-3012.html to look in the Control Panel for the Realtek audio control and change “environment” to none. It was set on default which was obviously bad.
