I had an issue with my magicJack phone. I could hear it ring and it had a dialtone but I could not dial out or receive calls. As a useful working indicator, I should see magicJack's stock symbol (CALL) on their desktop GUI. Instead, I observed the "No Audio Found" message. Predictably, I rebooted my PC a couple times but no change. I decided to visit the PC's Device Manager.
I invoked the "Control Panel"=>"Hardware and Sound"=>"Device Manager"=>"Sound, video and game controllers" and then uninstalled the USB Internet Phone by TigerJet driver. Then I physically removed the magicJack device from the computer's USB port and then reattached it about 20-30 seconds later. Its driver was automatically found and re-installed. Now I could see magicJack's Stock Symbol: CALL on their GUI. At any rate, it works.
I never had a issue before but I think I had a conflict with another recently installed USB device.
Of course, you might get this error and it's something else. This is what worked for me.
By the way, the OS name is Windows 7.

I am doing a few aesthetic upgrades, so naturally I want to backup some of my website files. However, I do not want everything, i.e. transient files such images. I tarred up the website's primary directory but excluded its images sub-directory.
Frankly speaking, I did not want to waste time and bandwidth downloading images. Here is the syntax to exclude a directory.
# tar cvfp mytarball.tar /mypath/Example.com_DIR --exclude=/mypath/Example.com_DIR/images
Tar everything in the current directory but exclude two files
# tar cvpf mytar.tar * --exclude=index.html --exclude=myimage.png
