Cannot get any sound except through USB headphones

I am completely lost here.
I recently installed Sound Blaster Audigy sound card. It worked for a brief period but then turned out to be to glitchy (was difficult to install and stopped working a couple of times). No problem. I uninstalled the Creative Technology drivers, removed the sound card itself and wanted to proceed back to using my old integrated sound card.

Nope.

For some unexplicable reason, my PC decided that it will not play any sounds any more.
The little green bar indicates it's receiving sound, there's no driver faults, it opens and plays all the audio programs and youtube videos like always, I made sure I've selected the right default playback device but I cannot get it to make a sound anymore. The only way to get anything out of it is to plug in USB headphones which work like a charm. It really seems as if I have a mute button pressed somewhere and the sound doesn't get through.

Now I'm not new to hardware/software issues so I have tried absolutely everything that the first 20 replies here are going to suggest. I've checked the drivers which seemed to be fine, than deleted the drivers completely, rebooted and let the PC update them automatically, after no success deleted them again from device manager, manually got the realtek drivers which always do the trick - still no luck, made sure I've selected the right default playpack device, checked the jack port, checked the cable itself, tested the existing speakers, tried plugging in a different speaker...

I'm running out of ideas.
I'm suspecting the Creative drivers deleted a certain .dll or something that's preventing the windows from getting the sound through, but it's all a guess and a bit beyond my knowledge.

I'm running Windows 8.1 64x.
Any ideas?

Thanks,
Alex

IF your on-board audio system is by Realtek, you may have run into trouble with an interesting feature of that system called jack re-assignment. On my system, here's what it does.

If you start from nothing plugged into the jacks and plug one thing in (say, the green plug for front left / right speakers into the green socket) a small window will pop up on screen saying it just detected a new item plugged in and asking what that is. It usually suggests what it might be, and often is correct. If you simply ignore that screen, it will time out and disappear and NOT use the default it suggested. Instead it simply will not send out a signal on that socket because it does not know what was plugged in. You MUST answer the query on that little...

You MUST answer the query on that little screen in order to set the correct connected device.

If you have not done this already, I suggest this sequence.
1. Unplug all your sound devices from the back panel. Shut down, then reboot. The Realtek driver will detect that nothing is connected, and will need input for all new connections.
2. Arrange your system so you can plug in devices on the back and still see the screen and have access to your keyboard / mouse.
3. Plug in ONE item - say, front speakers. When the window pops up, answer it and it will go away. Now do another device, and repeat.
4. When you have all items re-connected and have told the system what each is, you should have sounds again.
