No sound. Tried (almost) everything

Hello world,

So my computer isn't producing any sound at all.

I've checked the drivers and they say their working and present.
I've tried testing my audio devices on other systems and they work (I primarily use headphones)
I've trying restoring the default on my playback settings.
I've tried updating drivers.
I've tried restarting both the audio and the audio endpoint builder on services.

It's a windows 7 PC.
I run a sound blaster ZxR to manage the sound. I've tried unplugging it and plugging it back in. I've tried different audio ports to see if it helps but I still have no sound.

I'm not sure if I've missed to try everything but I feel like I've pretty much went through all my options
I just got it back from a repair shop and thought maybe it was my soundcard was physically tampered with but it says it's working in the settings so I'm not sure.

If you could give me any ideas or feedback that would be great.
