However, it recently developed another issue with the sound. In addition to the hummmm and standby/fan issue, the volume is now very quiet. I'd guesstimate that it is about 40% as loud as it used to be, with everything cranked to the max. Got on the phone with Dell... pointed the tech to this thread... and he claimed he hadn't heard anything about a mobo revision. (Very disconcerting...aargh) Anyway, he offered to send me a new fan assembly/soundcard to see if that fixes the issue. I told him that I was willing to give it a shot. (Might as well be nice.) The parts should show up in a day or two, so I'll post again to let you guys know how it went.
