I have an issue with low jet engine sounds in the cockpit. With default 738, till it reaches the speedsof 60-70 knots on take-off roll, sound of the engine is not heard. Today I installed PMDG 737 NGX. It got worse. I don’t hear engine sounds in the 2D cockpit. In the VC mode only when I change the view to back (view of cockpit door) I hear engine sound. With smaller planes there is no problem. Settings in the Sound Options are to Max. I checked the speaker settings too. I do not have this problem in fs9 but in only in fsx. Already I reinstalled fsx twice but it did not improve. I posted my problem in another forum, I could not get any help. I hope someone here helps me. Ramana

Hi Ramana, i know some other guys have reported sound problems and I too have an issue. Maybe it's best to wait for the upcoming service pack, hopefully soon, to see if these issues have been resolved.

Hi Howard, I read in one of the forums that its got something to do with service packs. I have 1 and 2 installed. I cant figure it out.It is frustating.Cant enjoy the wonderful CFM sounds. Ramana

You may care to check whether you have your sound config set up to stereo and not surround sound or similar. Chris David

Ramana, This is easy to fix - the reason for this behaviour has to do with you OS and nothing to do with FSX. You have set "Surround Sound Mode" in your OS Sound Options while you are using "Stereo Speakers". Goto your sound card options in Windows and turn off Surround Sound and other special effects unique to your soundcard like ambience, 3D effects, reverb and everything else. Then set the FSX and PMDG sound levels back to 50 and you will be fine.

M board is Intel DH67CL.It has 10 channel high definition audio with multi streaming capability.I understand, it does not reqiure sound card.When I tried to make the adjustmenet as suggested by Armen L Cholakian with inbuilt audio system (Realtec audio manager) like changing 5.1 to stereo and turning off sorround effect the speakers are going dead,

Aaah, interesting thread. I too have the Realtec audio. I will be waiting to see the outcome of this....

Try double tapping Q. It resets the audio for FSX, because there is a known bug in the game that if you switch cameras while taking off, then come back to the cockpit, the sound will be lowered.

That suggests to me you have not plugged your speakers into the correct physical outputs of your sound card - for Stereo output only you should be plugging your speakers into the "Front Left / Right" physical output.

Sorry for late response.Thank You Armen L Cholakian. Your advise worked. Great to hear all those wonderful sounds. Especially PMDG NGX. Regards, Ramana

Glad to help!
