Just finished a PC build in a Gamdias M4M case, really nice case but its mm tight if you put radiators up top haha, anyway all works apart from front audio which is weak and scratchy. Pretty sure the problem here is no cable in pin 4 which reference says should be 5v power? But the wire doesn't even seem to be in the bundle.

So what are my options here apart from unloading everything, returning the case and a rebuild?

Suspect HD Audio connector
