I've just spent the last 5 hours trying everything I could think of. Although, why what I did would make any difference I haven't a clue. I hadn't changed, or installed anything that would make any difference. I copied clicking tracks from my PC onto my Android Tablet and they played fine. I could play tracks from YouTube without any problem, but if I saved them, then played them from my PC there would be clicke upon click? I changed my speakers, no difference. I searched the internet, for a solution, but to no avail. I checked, changed and changed back again, everything in my Sound Blaster Control Panel. Then while I was setting up the headphones, I noted the options...
Stereo (as I only have 2 front speakers, this is what it was set to)
I thought to myself...'what is the difference between 'Stereo' and 'Stereo Direct'?'...So I thought I'd give it a go. As soon as I did all the clicking stopped?!
If anyone's got any idea and would like to share it with me I'd like to know.
