Hmmm....I have just noticed that the Xonar DX control centre doesn't control the volume of my audio. For example..if I raise or lower the volume it doesn't alter the volume at all. Also, if I mute it from wothin the control centre it doesn't mute! The driver is installed etc and I have no idea why this is happening. Any ideas (seems I am spamming this forum with questions again!)
Never mind. After a lot of faffing round I have sorted it. Had to uninstall drivers completely and then re install (took a couple of attempts though....driver install kept freezing).
