Windows 7 sound suddenly stopped working

Specs: Windows7 32bit, Not sure
A friend of mine has a PC which is pre-installed with Windows7. The sound problem arised a few weeks back. He called me and told me that his computer has stopped emitting any sound. I went to his place to have a look at it and I was puzzled by wat I saw. According to Windows7, everything is as it should be and sound is supposed come out, but no sound it coming out the speakers. I've checked everything from the advanced volume control to device manager and everything is fine. He has Realtech HD installed and there's nothing wrong with it since its configurations application show that everything is fine. There are no error messages at all. The default audio device is set on "Speakers", which to my knowledge is it what its supposed to be. Changing it to High Definition didnt help either. Every media plays without any problems except that there's no sound. I've tried Driver Roll-back, updating drivers, System Restore to no avail. Sound Troubleshooter says everything is fine. I can here a bit of static when I plug and unplug the speakers and headphones from all audio jacks, also the computer can see wen I plug and unplug speakers meanin the audio jacks are workin properly. Am I missing something here? Is there anything that I havent done/tried? I'm not really a tech-savvy, but I sure know my way around a computer, both software and hardware. I wish I could give the system specs of the computer, but I'm not anywhere close to his place to check his computer. I'd appreciate any help I could get from you guys. Also feel free to ask any questions, but my answers might be limited since I'm not anywhere close to this guy's computer. Thank you.

Have you checked to see if the speakers have been muted, click on speaker icon to check.
