Hello, I'm having a problem in PMDG737 upper panel.When I push any of those switches the engine soundstops and starts again after the switch sound. Seemslike it plays only one channel. I have an integrated audio AC'97 in my Asus P4P800 motherboard. I have all latest drivers including directx.Whith my old Asus motherboard K7T266pro2 everything workedright. Could anybody help?Markus Makela

Make sure you have plenty of sound channels assigned under options>sound.VinPMDGwww.precisionmanuals.comhttp://www.vinscimone.com/dancnkid.gif

Dear Vin,If ou mean those sliders in FS9>options>settings>sound theyare all (6) ticked and active. But if You ment somethingdifferent could You be more precise.When I push a button in upper panel the engine sound cutsoff something like a 1/4 sec. If I cannot proceed with thisproblem then how to deactivate all upper panel sounds?Yours,Markus M

Hi,What brand of sound card is this 'integrated audio AC'97' card? I'm sorry to inform you I have seen a number of people complain of sound problems when using an integrated/onboard sound card. There are a couple of things I can think of that you could try to do to cure the problem.#1 - Make certain you have the latest drivers installed for this integrated sound card.#2 - Click Start --> Run --> (type in) DxDiag --> Click on the 'Sound' Tab --> turn down the 'Hardware Sound Acceleration Level' to medium or all the way down to low.#3 - Get a different sound card such as the Creative Soundblaster Audigy 2 which is a PCI slot based add-in sound card.Regards,Jimmy Richards
