Alright everyone, before I embarass myself in the Gear Porn thread...
I have a new Yamaha Amp, and it supports HDMI in. When I replaced my old Sony receiver, I had my devices (DVR, PS3) connected via optical cable to the sound system, and the HDMI cables to the TV. It worked flawlessly; 5.1 Dolby, PLII, and DTS all worked fine.
When I first hooked up my new receiver, I took the HDMI cables from the devices and plugged them into the receiever. From there, I took an HDMI from the receiver to the TV. In my head, it makes sense: sound from the devices go out to the receiver, and the receiver can transit the signal to the TV for video.
It didn't quite work that way: The sound refuses to play at the receiver level, instead it passes through to to the TV, and will only output there, at the speakers on the TV itself. Frustrated, I decided to RTFM. Turns out that any HDMI signals are not output at the receiver by design. From the manual:
Information on HDMI:
Audio signals input at the HDMI jack are not output from any speaker terminals but output from the connected video monitor. To enjoy sound from speakers connected to this unit,
- make an analog or digital connection besides the HDMI connection.
- mute the volume of the connected video monitor
Which, to me doesn't make sense: If I want PCM 5.1 audio, which the amp does support (up to 96Khz), why do I have to make another connection? Defeated, I went back to how I had it on my old set up: HDMI straight from the devices to the TV, and optical out from the devices to the receiver. Everything looks and sounds great: 5.1, DTS, and Pro Logic II. No problems.
Then, I upgraded my TV to a new 52" LCD. It supports optical out. "Hmm," I thought. I then plugged the HDMI back into the receiver, and put the HDMI from there to the TV. I took an optical cable from the TV to the receiver. Success! But: I can't get 5.1 sound. Everything, regardless of signal, only shows up as "Pro Logic" on my receiver. The PCM light is lit, but I don't think my TV decodes 5.1 signals. Does that sound right?
So here's my question: am I doing this wrong? What's the "right" way to hook up a theatre system this way? I get the feeling that my receiver is the issue here?
