Hi there, I have a problem with my NGX. I do not have any cockpit sounds (EGPWS, TCAS, Fire bells, Cautions, switches clicks etc). Other sounds (engines, wind etc) are OK. And its only with NGX. There is no such issue with any other aircraft (including PMDG 744X). My Windows playback device is set to stereo, as it is stereo. In FSX sound device is default (and switching to other options does not help). And when I go to sound options on aircraft's FMC/CDU it says 'device: none' and when I click it, there are no sound devices. I can't think of anything else to fix it. Clicking 'Q' twice does not help either. Can any user or PMDG STAFF here help me? Thanks!
