all of a sudden my HTHD is having problems after working flawlesly since it first came out. during a TF2 game all this loud distortion suddenly developed and stopped just as quickly. now if i turn up the system volume past anything 25% during audio playback i get very bad distortion. the funny thing is that it seems to come and go. it's not constant except for a very low rumbling/spattering distortion that wasn't there before with the intermittent loud distortion randomly happening. i've uninstalled/reinstalled drivers numerous times using the latest auzentech drivers and also the latest daniel k drivers. i've tried other cards and they work fine. is my card fried? what caused this? this doesn't seem to to be the same issue as the well known crackling issue with creative cards.
