[Support][Win]No sound

Game seams to be otherwise working fine but I have no sound.

I have tried (in order)
*Test sound is working for other programs - it was
*checked audio not muted - nothing muted in mixer
*Restart the computer - same result
*Verify game cache via steam - no errors
*Deleted offline cache restarted and reinstalled - same result
*Checked default sound device - when opening the setting (Ctrl panel>sound>playback devices tab)

Windows popup stating that errors with the sound devices settings had been detected…
I clicked OK to reset them.
now working fine…
