A coincidence perhaps - Yes I know to days date but this is what happened this morning. My sounds by the way come via USB Headphone set.
Suddenly no sound So set about usual checks- Volume on phone Volume in the AC97 panel All saying all OK all working. Check USB devices - All OK Unplug phones - replug phones -get New hardware and working message.
Then I noticed the time- yes the system did auto change at the weekend But suddenly it had advanced yet another hour instead of 10.30 BST it is showing 11.30.
