A friend of mine called me earlier today wanting to know if there were "different types of HDMI cable". The reason he was asking was that he couldn't get audio from his PS3 through to his brand spanking new HK AVR245.
Of course I told him no, that all HDMI cables supported audio and I dug out the online manual for his receiver to try to figure out the issue. It turns out that this crappy HK receiver with HMDI "switching" only manages a half arsed job of HDMI and unfortunately audio isn't a part of the deal; any HDMI video input has to get its audio from optical or coax source connections (pp14 of the manual). I mean, really, how silly is that? And only 50wpc too.
Why bother when, for the same price, you can get an Onkyo/Yamaha/Denon/Pioneer with more features and more power?
Oh, and any of you guys with a PS3 hoping to get TruHD out of them are in for a surprise if you try to do it without HDMI audio; it's just not possible folks.
