My xonar will ocassionally out of nowhere just start this incredibly loud high pitched ringing noise and it won't stop until I reset the computer. It's terrifying because I'm afraid of it damaging my ears it's so loud. It happens about once a week probably about 4 times now. What could cause this, how to prevent it, & is this a common prob? Also for a duration of 1 second with phones on could this damage my ears? please help Thanks My setup is xonar essense stx pci 100mhz windows 7 ultimate x64 winamp newest with kernal streaming output, allow 24 bit & dithering. windows control panel is set at 24 bit 48000. prob was still the same when it was at 44100. xonar audio center set at 48000 2 channel with dolby headphone & 7.1 & EQ. headphone amp high gain +12db using headphone out on back of card to ATH-AD700's.
