After i installed SP1-C, the sound from NGX have been disapear. When i take a look into FMC-> PMDG Setup-> Options-> sound-> divice, my headset divice are not there. I hear the traffic around me on the airport, but not from the NGX plane like when i twist the knobs, switch the switches, start the APU etc. If i reinstall NGX and put the SP1 and SP1-B back, the sound divice (headset) is back in normal and i got the sound from NGX. So why do i have this problem when i put in SP1-C?Edit: Put soom pictures here:Here with Sp1-B everthing works fine:Her with Sp1-C:

no problème for me.

Hi, just a quick guess, sometimes when you change the sound device settings @ the CDU you need to exit FSX and return back for the change to make a full effect, depending on the complexity of sound system you have.Hope this will workRegards

I have tried that. Even restarted the hardware and start/restarted FSX, but the problem is still there. Thanks for the tips btw. :)
