The easy answer is: same thing I was using it for 10 and 20 years ago. Audio equipment doesn't age nearly as quickly as personal computers. I'm not going to replace my entertainment system just because there's a new Mac.
Also, I've had compatibility problems with HDMI between my old Mac Mini and my receiver. I don't know how to troubleshoot those sorts of issues. I do know that optical audio always works perfectly with every device I've ever used it with, though.
