No sound output from any jack. Did I burn my soundcard?

I have an "MSI 760GM-E51(FX)" mainboard with integrated Realtek HD Audio (ALC889 audio chip).

 

Once when connecting my PC to a Mixer (both of which were not earthed and were connected to different wall sockets) I got an electric shock while touching the audio cable and my PC case.

 

When I connected the audio cable to the PC's rear panel, although Windows Volume control showed sound being output, no signal was going out of any of the 5 output sockets: 

  • front panel headphone out; 
  • rear panel green
  • rear panel black
  • rear panel orange
  • rear panel grey
Was the electric shock from connecting the cable able to damage the soundcard?

 

Both mic inputs, front and rear function normally. 

Rear blue line input also works.

Oh, it is too late for that. Probably will just grab a PCIe sound card for now and buy a new motherboard later
