Lost Audio

So I went to Control Panel > Sound > Playback tab to test the speakers on this lappy because I thought one was sounding raspy(it's my daughter's and she plays it loud) I right clicked on Speakers and hit Test.I got the little chime from both speakers and went to test them a second time at a lower volume level and hit Disable from the drop down by mistake.Let the fun begin!! So now under playback,we have no device installed-Crap!! So I simply right clicked the speaker icon in the notification area(which now had the red X) and chose troubleshoot.That appeared to go well as reported by Windows,and a check back under the Playback tab showed my speakers returned with a green check mark ready to go.Great-thought I dodged a bullet until I hit test again launching a window telling me that "The device is being used by another application-please close blah blah)Tried a reboot and same thing.There are no external devices plugged in,and I'm only sitting at the desktop with the Sound window open.There was no Windows start up sound at boot and there's no audio to be had anywhere.Device Manager reports the device working properly,and that I have the latest driver installed.All instances of the audio were fine until I blundered here.And thanks to the optimized defrag of the hard drive,there are no restore points available.Any ideas??

Right click in the Playback window. If unchecked, click "Show disabled devices". Do the same for "Show disconnected devices".

What devices are now listed in Playback? Can you post a screenshot of the Playback window?

Thanks for the quick reply Carolyn.Just for Sh!ts & Giggles,I chose to roll back the driver for the audio device and behold!!-I now have Speakers,Headphones,and another Digital Audio Device (marked as ready) under the playback tab.Prior to that I had Speakers only,and had already done as you suggest(called up and checked both boxes) with only "Speakers" turning up on the list.I have no explanation for this as the previous installed driver(s) were working fine until the accidental deletion of the speakers from under the Playback tab.Time for Dad to call it a day for the Spring cleaning and leave well enough alone!! With all the Music files on here,Dad wouldn't have lived to see Father's Day

Glad you were able to get this sorted. :)
