OptiPlex 790MT Constant Distortion
Hi,
Since the day one, I am having constant distortion (hiss) sound coming from the left speaker from front and the rear jacks of the OptiPlex 790, even when there is nothing played.
When I play a sound, right speaker seem to be working fine, but the left (the one which is hissing all the time) one's sound is cracking too.
Even if I put the speakers to MUTE, the hiss sound is there and constant.
I have also tried other speakers and headphones.
I have tried all the drivers I could find, even the ones on the Realtek Website (HD audio) and have updated the BIOS to the latest version.
OS: Win 7 Enterprise SP1
Could it be a manufacture defect ? Any ideas ?

Hi wiseguytr,
What if you unplug the speakers and use headphones?

Hi,
Though I thought I had tried that formula, it seems I have not.
It has worked, but there is still a slight hiss sound coming from both of the earphones (not worse as before though).
