Default Dolby Digital setting won't save

I have a Scientific Atlanta Explorer 8300 DVR with Time Warner Cable and a Yamaha HTR-6130
audio receiver. The problem I am having is that when I select 'Dolby Digital' on the DVR's audio settings menu, the digital setting remains active until I turn off the receiver. When I turn the TV and receiver back on, the audio setting defaults back to 'HDMI' and the audio signal is no longer digital.

I have never run into this problem before, I am not sure why it happened now. Anyone have any advice on how I can get the Dolby Digital setting to save? Thanks


(My DVR is connected to my receiver via HDMI and optical)

Is it possible that your input settings for the dvr/hdmi are set to direct?

You will have to pardon my ignorance but I am quite new to all of this, what do you mean exactly?

Another thing I noticed is that if I only turn off the DVR and leave the receiver and TV on, the dolby digital setting will remain. When I turn on all three devices the digital signal will remain for about 5 seconds until the DTV/TV setting on the receiver clicks on, then it switches back to PCM.

First off, let me apologize. I reread your post and now realize the issue is with your cable box and not the receiver, correct? How is everything connected? cable->receiver via hdmi and then receiver->TV via hdmi? That is what I would recommend if not. If this is how you are connected can you hear a difference when the audio output is selected as hdmi rather than DD? The reason I ask is I am wondering if when set to hdmi it is passing the audio that is embedded in the programming. Hopefully someone familiar with cablebox can chime in on this.

The sound is completely different when it is on the default PCM setting which is why I want the Digital default setting back.

I am running the same HDMI setup as you mentioned above

(HDMI and optical from box to receiver, then HDMI from receiver to TV)

And I know this is something to do with the box because I also have a Playstation 3. When I turn on the Ps3 the receiver recognizes it as Dolby Digital and switches on its own, the way it used to with my cable box.

That sounds like an HDMI handshake issue. Can you turn off HDMI audio from the receiver to the TV? The TV is a two channel device and it may be instructing the cable box to transmit stereo PCM instead of DD 5.1. Even if you are using optical for audio, the HDMI handshake often controls the format of all digital outputs.

If you can't easily change the AVR's HDMI audio output, you can test this by simply unplugging the HDMI cable to the TV so that it isn't involved in the HDMI handshake.

Two things. First, I think Bislander may be on to something. I had the same problem you are describing when I got my new receiver. Since my TV is not Dolby Digital capable, the receiver was defaulting to PCM. My Sony receiver has HDMI audio settings of TV, TV/AMP, or AMP. When I changed the setting to AMP only, I was able to get DD all the time since the audio was not being sent to the TV.

Now this may have nothing to do with your problem, but I have to ask why you have HDMI and optical connections from the cable box to your receiver?

When I unplugged the hdmi cable, sound was still streaming but the audio setting went back to digital. When I plug in the HDMI cable again, the audio setting goes back to PCM and the DVR box switches back to 'HDMI' for the audio output.

Your receiver probably has a setting to turn off HDMI audio to the TV. That should solve your problem. The TV is identifying itself as a two channel audio device and your DVR outputs stereo PCM when that happens. Turning off HDMI audio will eliminate the HDMI audio handshake.

Yeah that has to be the issue because the "handshake" only happens when I turn on/off the tv, not when I turn off the receiver/cable box. I can't seem to figure out how to turn off hdmi audio on the receiver so I am going to give Yamaha a call tomorrow morning. Thanks again for your input.

Unfortunately, I don't see any way in the HTR-6130 manual to turn off HDMI audio.

Perhaps your TV has a setting to turn off the TV speakers. If so, it might stop IDing itself as a stereo device during the handshake when the speakers are turned off.

Or, perhaps your cable box has a way to turn off HDMI audio, which might also work.

Or, you can use component video cables instead of HDMI from your cable box. Then, there wouldn't be any HDMI handshake at all. That's probably the best alternative, provided you are happy with the video quality over component from your cable box.

I have always had the tv's speakers turned off. As for the box, the only audio setting on the box's menu is called 'Audio Output". This is the same list of choices (HDMI, Dolby Digital, Other) that I have to go to each time to switch the setting from HDMI to Dolby Digital because the Dolby Digital setting will not stay once the TV has been turned off.

I already know that using component cables keeps the digital settings since I have tested that already, but I can tell the difference in the picture quality (I rent a lot of HD movie off the 'on demand' feature).

The strangest thing about this is that I have been using this exact same set up for about 6 months and never had this problem until about a month ago when the cable company, Time Warner, updated the box's software with a new On Screen Navigator.

Also, my Playstation 3 still switches from PCM to dolby digital every time I use it, unlike the box.
