Question IS my sound module damaged?

[twinsynth]

I had sound working fine from the start (new system- aorus motherboard) but after i tried to connect a faulty rbg cable, the system shutdown, after a restart the sound stopped working but no driver errors. the only way i got sound was to connect it to my monitor via the graphics card. A system restore did nothing. do i just get a soundcard or is it fixable? and is there anyway to test my motherboards health?

I would consider either returning the motherboard to the retailer you bought it from (if possible) or contacting Gigabyte and seeing if you can have the board fixed/replaced under warranty.
