No playback devices
No recording devices
No midi playback devices
( ) use only default devices
PS: About the North Flag is really Norton 'Flag' that appears on the bottom right giving informations...I dont know the real name of that thing...

Sounds like your Laptop is not always detecting or enabling the installed audio hardware. The next time it fails try the following:
Right click on My Comuter and select "Manage"
Then click "Device manager"
Look for "Sound Video and Game controllers" There may be a Yellow Triangle with an exclamation mark next to where "Realtek HD audio output" is listed like the one by this post. Or, "Realtek HD audio output" may not be listed at all!
If it's not listed then right click and select "Scan for Hardware changes" and see if your Laptop detects it now. If it's listed with a triangle then double click and there should be an explanation as to what the problem is, you can report that back here or right click and select "Update Driver" Choose the option to install automatically and click next. The Laptop will go off and try and obtain updated drivers. It may find some but I doubt it.
If the device is listed without a triangle then you need to :
Go back to control panel, select audio devices and click the Audio Tab. If the drop down lists of audio hardware (see att screenshot) are working, see if contain the ones you listed earlier. If so select them and make sure the tickbox for use only default devices is ticked. If this works that it suggest some software you are running is changing your audio settings.
Try to see if there is a pattern, a certain application you run that next time causes no sound. Lots to do there so go see what happens.:smile:
