Well, first of all, the method you are using is the lowest quality. You should upgrade to a toslink(digital optical cable) or a digital RCA cable. The toslink is the best all around. But it is normal for some devices to have higher sound output than others.

Use HDMI because they combine picture and sound in one convenient cable. You can buy the cheapy ones because they work the same as the pricey ones with no degradation in sound quality or picture.

Max does recognize receiver over HDMI-CEC.
The problem is that DVI output is for video only. Macbook won't (and can't) output audio via DVI. So yamaha receives only video signal via the HDMI connector. You can check that by pressing Option button on yamaha remote and choosing Signal Info - you will see info about video, but no audio signal present.
