If you have a macbook pro (or any mac really) and use an HDMI cable to watch things on your TV, is the audio ok? Does the Moshi Mini cable work (the one from apple)?

I started watching Homeland last night from Amazon (using DH's laptop--a pc) and when hooking it up with an HDMI cable, the audio was crackly AKA annoying. I want to buy the one for the mac but wondering if anyone has used it for this and had any problems (or no problems).

THANKS!
