**Offical** Yamaha RX-V665 AV Receiver thread - Page 49

Two questions

1. I just fired up my RX-V665 for the first time. Got all my video routing correctly, but for some reason, when I have AV1 for the input [which is my Xbox 360 running in to AV1 Component Video and Optical Audio] I get no sound on my TV. I see that the audio is being decoded as Dolby Digital, but still no sound on the TV. Any idea what I could be doing wrong? TIA

EDIT: All audio and video is being sent to my TV via HDMI from the 665. Forgot to mention that before.

2. The OSD on my plasma (connected to 665 via HDMI) is jumpy. Meaning, the image jumps around a few px all the time. Is this common?

You need to change HDMI AUdio Output to either TV or AMP + TV if you don't have speakers connected yet. pg 42 of 565 manual.

EDIT: It's been a loooong day. I should have read more carefully...I assumed you were connected via hdmi, my bad and +1 to rdgrimes

The AVR cannot send any audio over HDMI except that which comes in as HDMI.

As to the video, check your scaling settings. The OSD will be whatever you have the AVR set at. "Through" is recommended in most cases.

Thanks... the more I thought about it, the more I came to that conclusion. I'll check the video settings for the OSD. Thanks

I'm not crazy about the YPAO on this unit. None of the automatic EQ settings sound very good and the speaker levels are very much off. For awhile I wasn't using a center channel, and with the YPAO settings, the phantom center channel was pulled to the left. Using Avia and a sound level meter, I set the reference volume to 0 on the receiver and set every channel to 80db SPL. Once this was done, the phantom center was locked in precisely between my loudspeakers. Imaging in music was also right on.

I do use YPAO to set the distance, that seems right, and can easily be verified with a tape measure.

Sounds like you have a lot of room reflections. That will really throw off the distance and level measurements as well as EQ.

Hey guys I had a quick question about the RX-V665:

sorry if this has already been answered several times, but do I want to have CinemaDSP on or do I want straight enhanced on to get better sound? I have my reciever set to 6.1 at the moment. I also have the audio decoder set to DTS-ES Mtrx. Thanks in advance!

There is NO "correct" setting; do whatever sounds "best" to you. With all 'post processors', the results are highly dependent on the source material content . . . giving results that vary from "truly dreadful" to "dramatically improved".

With a 'properly mixed' 5.1 movie (in your specific 6.1 environment), you should probably consider either the native DD 5.1 or DTS 5.1 decode with no post processing, or one of DTS-ES, DTS-EX, DTS-DPLIIx(Music), DD-EX, or DD-DPLIIx(Music) as your default. It's worth comparing that to the CinemaDSP modes, but my personal preference is usually NOT to use CinemaDSP enhancement. Don't be afraid to do what sounds best to you!

Note that CinemaDSP is significantly improved if you have a pair of Front Presence speakers in place.

I have not done the firmware update on my 665 that I got around this time last year. Should I still try to do it? I really have not had any problems until now with my PS3 connected to it via HDMI and the 665 is putting the audio out as PCM on the HDMI. Normally it was just saying spectacle or whatever DSP I picked. Any help or suggestions would be appreciated?

There's no reason to update FW unless you need the assignable inputs that it provides.

As to the rest of your post, it's not clear what the issue you're having is. If the AVR says "PCM", then that's what it's receiving from the PS3.

The whole PS3 bitstream vs PCM is a cluster.

There's arguments that the PS3 does some DAC conversion when converting bitstream to PCM, but most others say its a digital conversion so its moot. (and if it did do DAC things, it implies the PS3 has cheaper DACs than fancy AVRs)

The answer basically is: unless you have a > $1000 receiver, you are going to be fine with PCM.

I know with my 665, one mode is louder. But other than that...

I have an RX-V655 with a Cisco set-top box (AT&T U-Verse) plugged into HDMI-1. With rather irritating frquency, my TV shows a "No Video Signal" error message on an otherwise blank screen. The 655 display reads "Decoder Off." My question: am I losing video signal because my Decoder is switchnig to Off or does the decoder turn off because I lose a signal from my cable box? Each TV in my house has a set-top box and this problem doesn't happen on the other TVs so I suspect this is a problem with the receiver.

Any advice to correct the situation?

Hi RoamingJohn, sound like a possible HDCP handshake issue (which STB is wrost for). You can try using the other HDMI jacks (on receiver and Tv) or try turning on your equipment in a certain order. Like turn on Tv first then receiver and last STB. Or try cycling from one input source to another and back.

If still having issue, another option would be to run HDMI to Tv and Optical cable to receiver for audio. If you don't like to many cables to Tv and prefer the one HDMI to Tv from the receiver then use component cables from STB to receiver (which it will upconvert to HDMI) and Optical cable for audio.

You're being bit by the cable box blues. Some people wind up using component and optical outputs from cable boxes because they don't handle HDCP correctly. The 665 is HDCP compliant and will demand the same from cable boxes.

Usually with handshake errors, simply changing HDMI inputs and back again will resolve it. But the suggestion of running the HDMI direct to the TV is another work-around.

See that is just the thing. Like the post by Roaming John as well. It tells me my Decoder is off some maybe I need to change the hdmi switches and see what happens. I just like Yamaha receivers overall and apparently the PS3 does not like them right now.

My PS3 and Yamaha work flawlessly...

Have you tried adjusting the audio output settings of your PS3? It sounds like it may not be outputting audio over HDMI.

Hey Guys,

Just hooked up a new 665 and i'm not sure if i'm doing something wrong. I'm a super noob but I have Dish Network, LG Blue ray player and Xbox 360 all hooked up via HDMI and HDMI to a 63" Samsung plasma. When playing a BR disc or watching TV or Playing Xbox i cannot get the 665 to say anything but DSP Cinema unless i push the pure direct button. Should the display say anything different like Dolby pro logic or DTS? Can i switch and have choices if so how do i do that? I'm just very confused.

3 suggestions:

1) Read the manual
2) Read the manual
3) Read the manual.

In the mean time, just hit the "straight" button and leave it there.

wow never thought of that.

Few questions for 665 owners, I looking for an AVR for my home office to connect my HTPC (GA-E7AUM-DS2H) via HDMI primarily for headphone listening. Not intending to connect any speakers.
1> Which pre-out can be used to connect to an external headphone amp?
2> Any one has any experience in using high impedance full-size headphones on 665? I am looking at Beyerdynamic DT 150, Impedance 250 ohms, Sensitivity 97dB SPL/mW and Maximum Input Power 100 mW
Thx

Thanks to JChin and rdgrimes. I switched to HDMI 2 and the problem with signal loss seems to have been eliminated.

Sale on these now...check out my thread here.

Does that thread exist?

Sorry, it is in "Great Found Deals"...I'll post it here:

Hey everyone,

Im using a 665 and had a question about the pass through feature. Does the red light stay on while your tv is off? I'm using a dish network vip722k and sony BD player connected via HDMI. The dish receiver is always on, so im guessing thats why the 665 is always lit up? Is there a loss of sound quality if I run an HDMI from the dish box straight to the TV and then run an optical out to the 665? Would you all recomend this?

The manual also says that 1-3 watts are consumed in the HDMI pass through while the unit is on standby. Not much at all, but still something.

I think that's covered in the manual

Definitely not recommended. TV's cannot pass 5.1 audio out through their optical ports except from broadcast HD stations. You will get low quality 2-ch audio only from other inputs on the TV.

I picked up one of these a week ago and it's been working great except for one thing: I cannot get it to work with my HD Sattelite box. I hooked it up using DVI->HDMI into HDMI 2 and plugged the AV cables into Audio 2. I set HDMI 2 and Audio 2 to talk to each other. When I turned to Audio 2 I can hear the TV but I do not see any picture. When I do not have the audio hooked up for Audio2/HDMI2 pointing towards each other I do not see a picture either.

My TV tells me that is trying to find a signal/no signal over and over. On the receiver I see the orange HDMI light blinking on and off every second. I was able to get it working using composite cables, but that kind of defeats the point of having HD...

Is there something I'm missing here?

Damn it.. just read this in the manual:

This unit is not compatible with HDCP-incompatible HDMI or DVI components.

Does that mean I'm out of luck? Should I just give in and buy some component cables?

HDMI->DVI converters can sometimes work. More likely it's a problem with the cable box, since they are well known for these issues. In any case. DVI is HDCP compatible. Since there's no compelling reason to need HDMI from a cable box, the usual work-around is to use component video plus optical. If the cable box allows it, you could also run HDMI direct to the TV and optical to the AVR.

You should also verify that you have correctly assigned the HDMI-2 video input to the Audio 2 input. Instructions for doing that are in the manual supplement and also included with the firmware update download.
