Hey all... I have this same issue. I'm running Dayz 1.7.1.1 and Arma Beta. I try'd setting windows sound settings to stereo and 5.1 no result. I remove'd all files from the \addons\@dayz amp and re downloaded. No result. Made sure my sound drivers are up to date. Weird thing is that my sound is fine in Arma2 (multiplayer) itself but when i connect to a dayz server my sound is gone.. Anyone got some tips or even a solution?
