This problem is happening to many whpo have upgraded. I choose Stereo Mix, set my pc audio to play my music through Stereo Mix. However there is no signal playing in chat. I need a solution or will soon be exiting CF because Chat Mic DJ is no longer an option and it makes me extremley disinterested without it.
Works for us, even on the update, im pressuming you mean the update when you say "upgrade". Email the helpesk or jump back to the previous version until you establish what the issue is.
