Annoying Echo Sound Every 40-60 Minutes?

[grizzly77]

For the past few weeks now this annoying echoy sound will play through my speakers every so often numerous times a day. Is there any way to track down certain sounds? Has anybody had this issue?

Hard to say with your limited information. But, I would suspect some open program, maybe in the Notification area, is causing it.
