Hello i have a xonar dg 5.1 sound card. On some games some sounds doesnt come when i use abilities one after another fast etc. Not certain sounds this can happen to any sound in game and also when i click windows folders etc the click sound goes weird it comes like ' cli cli cli ' . On my older creative card i had the same problem and i found out that when i disable crystalizer , problem gets solved. On this card the same thing is GX mode i think but my GX mode is closed and i must say even if i disable or enable it, it just doesnt make any difference. My audio card needs to go warranty or this can be handled with software things etc? and btw i have the latest driver from asus site and also i tried to reinstal drivers etc nothing changes and last my 7.1 virtual and dolby mode is also disabled .
