I have had the 737-700 for about 6 months now and have been thrilled. My Dad got me the -800 for christmas. Well, I have flown it a few times and it is even better than the 700.Here is my issue, I installed the 800 and flew it offline. It did great. So I decided to take her up for a flight online with VATSIM. I loaded up the aircraft, got everything set, FMC and a like. Minimized FS and started my modem (I am on dial up). While it was dialing, I went back into FS and discovered that I had no sound. Just the recirculating fans, no engine noise, no toggle clicks, no seat belt ding, nothing. I closed down FS and restarted her, no sound. I reloaded the computer, went into FS and the 738 sound was back, went to restart the dial up process and while it was dialing I went back into FS and the sound was gone again. I even tried it by waiting until the dial up process was dome before going back into FS. It apparently is conflicting with my modem. Has anyone heard of this? My PSS works fine, as does my other add on aircraft, just the PMDG is doing this. I love this aircraft and love flying online. Can someone help me. I have tried this in window mode and full screen, nothing works.Dave

Try dialing up before you start FS. :)

>Try dialing up before you start FS. :)Tried it, no go.

Have you checked your modem driver settings to ensure it shares sound card once it dials? Or no sound at all?

I updated my SB Audigy 2 drivers and that has apparently fixed the issue. Not sure why. But I completed a flight last night and she was running perfectly.
