In an attempt to fix this, I've posted into user.cfg a few lines from another thread that purported to help, and have turned my audio format to 16 bit 44.1khz. Also tried a different sound card and a headset. And tried the 'repair' thingy. None of these did enough of an improvement for me to really notice.
Am I the only one who still has this problem? No one else seems to be posting about it anymore...
