Hi all, very nice forums I stumbled on here! I'm new to the whole HD Audio thing. I'm confused as heck about receivers with HDMI. Very soon my family will be investing in a home theater and I suggested it be HD. I'm now tasked with finding everything necessary under a certain budget and the one thing I'm confused about is receivers. Our Blu-Ray player is a PS3 and right now we're using an RCA RTD 255 for sound(it's crap but it's all we have, economy sucks so this HT will be budget conscious). What I want to know is, if we connect the PS3 to a receiver through HDMI and from the receiver to a projector, will the video pass through and go straight to the projector? And will the audio follow or does it go through the receiver to the speakers? Please, bare with me I'm a newbie at this so I may not even be explaining it right. Any help would be appreciated, thanks!

HDMI will transmit both audio and video from the PS3. An HDMI audio capable receiver can sit between the TV and the PS3 to switch audio/video to the TV, and to play back the audio coming from the PS3.


You mentioned a projector. That usually implies no audio requirements, so audio is no problem.


Passing audio from a PS3 to a TV can be tricky though, because HDMI is a two way pipe. It tells the PS3 what the video capabilities are of the receiving device. Depending on the AVR, and it's settings, attempting to send audio to a TV from a PS3 through a receiver can result in the receiver getting two channel audio only. There are some newer receivers which can pass HDMI audio through when they are in standbye mode. This is nice because you can say, watch TV from a DVR with your receiver off, and get audio. And when you want to play a DVD, you turn on your receiver and it will then play the multi-channel audio.


A brief note on lossless audio from Blu-ray discs might be helpful. While lossless audio is theoretically better than lossy audio, all evidence points to Blu-ray lossy audio as being very high quality. A listening test was done and concluded that differences between high rate Dolby Digital from a Blu-ray disc was very close to lossless quality. So lossless audio is not critical in my opinion.


The stickied AVR FAQ covers HDMI and lossless audio in more detail.

While this is true to some extent, you are the only one who can judge this. Listening test are not done in your home with your equipment. Everything sound great on a 10k$ setup. It's another story on a common joe setup. I know that with my old Sony 810, LPCM sound way better than plain old DD, especially on titles like Casino Royal.


The Sony didn't last long and I was back with my old pre-hdmi Pioneer vsx810s and DD did sound better on it than on the Sony, but I didn't have an HDMI port on it to test lossless and compare.


I'll have to re-test that now with my brand new Denon avr-890.
