Windows 7: No sound through earplugs, although plugging in is recognized

Yes well, that didnt take too long to break again. I've enjoyed the sound through earphones for three times, then I switched one time to Linux, and now its broken again. Reinstalling drivers doesnt solve it.

It almost seems like Linux and Windows are interacting or communicating differently with the sound (chip or card?). Almost like one puts it in a certain status, and then Windows is not able to work with it anymore. Although the normal sound (through speakers), continues to work always. So, maybe it has something to do with putting the 3.5 jack connection point in a certain mode.

Is there any way to reset certain pieces of hardware, like for example the onboard sound card, or 3.5 jack connection point?

EDIT: well this problem seems to be very odd to say the least. After a quick search on the Internet I found that sound problems with dual boot systems occur more often. I found a suggestion to put Windows to sleep and then wake up, everything should be working. And what happens? It works! So at least I have a workaround, but its just crazy, and if anyone can point out whats the reason for this I would be happy.

EDIT2: I can imagine that during wake-up of the system, ports and hardware is reinitialized and setup again to some extent. If this is true for the onboard and audio ports, it could be the reason why after a sleep - wakeup cycle, everything works as it should be. It could also point at the possible cause that when its not working, sound is directed to the HDMI output, instead of the 3.5 jack output.

If someone has a command to reinitialize the sound card and/or audio ports, similar to a sleep and wakeup cycle, it would be nice.

Ok something odd going on here and I am not sure what, because I have not used a dual boot for years now - seems almost like you have to install the driver while in Linux and also when in Windows. There again if you have to do that with the audio then it follows that has to be done with all the drivers??

Perhaps running Linux wrecks the Windows drivers and I did find this and while it doesn't solve the problem may have something to do with it what I am not sure but it does look like Linux has audio issues.
