Hello once again simmers. Yesterday I made a grate flight with my 737. I thank you for sincerely and quickly replying to my queries. But I want one suggestion that when I turn on my plane, I cannot here on vatsim. However I made out yesterday though.

Thank you

Do you mean you cant here vatsim because the engines are to loud? If you click on the speaker icon on the bottom right hand side of your screen and then click "mixer"  there will be a slider the controls vatsim volume, you just need to play around with them a bit

If you have both headphones and speakers, you can use FSX Sound settings to send FSX sounds to your speakers, then set VATSIM to use your headphones. But if that will disturb others around you then using the mixer suggested above is good, or in the FSX Sound settings, move the volume sliders to the left to turn down the volume of the airplane sounds.

Hmm.. ok guys thank you very much
