How to keep the sound coming from my surround sound without having to change the setting on my TV...

post #1 of 12
Thread Starter 
I have an Onkyo HT-R557 home theater system and a Orion LCD HDTV. I have my PS3 and cable box connected to the receiver by HDMI cables and then connected to the TV by an HDMI cable and Coax cable. The problem I'm having is every time I change the input on the TV or the PS3 changes to movie or game I have to change the TV sound Digital Audio Output setting off of PCM then back to PCM. How do I get ti so that I don't have to change the setting every time?

Thanks

Why do you have a coax connection from the TV to the receiver? If all your devices are attached to the receiver, then the coax connection serves no purpose. Do you have HDMI CEC engaged on your TV and receiver? That can have unexpected consequences.

That's what I thought too but I read the manual for the receiver and that what it said had to be done.

I don't understand. First - why the coax connection? Second - what did the manual say?

It appears your receiver just does HDMI pass through and can't process audio arriving over HDMI. So, for sound, you need to use an optical or coax connection from each device to the receiver, not from the TV to the receiver.

Are you sure you worded that right? What kind of receiver cannot process audio arriving over HDMI?

It used to be fairly common for cheap receivers to simply act like HDMI switches. They can pass the video and audio of the selected HDMI source to the output port, but they cannot process the picture and sound themselves. If you want such receivers to process sound, you have to send it to them over separate digital or analog connections. p28 of the manual linked by the OP:

✽ Audio and video signals received via the HDMI IN 1 and 2 jacks are output by the HDMI OUT jack as they
are (HDMI pass-through), so even if you only make the connections in steps 1 and 2, your TV will output
sound. However, if you want to listen through the speakers connected to the AV receiver, in addition to an
HDMI connection, you’ll also need to make a separate analog or digital audio connection.

BIslander is correct. Your Onkyo AVR will only pass through the audio to the TV when using ONLY HDMI. To enjoy surround sound you must make digital connections to your PS3 and cable box, then mute sound on the TV.

I suspect tealfire88 is using the coax connection from the TV to send audio back to the sound system. The AVR passes audio from the devices to the TV over HDMI and the set sends it back to the AVR over coax. But, that doesn't appear to worry very well when switching sources. Plus, the TV output is likely limited to stereo. That's why I suggested making direct audio connections from each device to the receiver.

OK Ill try the coax from each device to the receiver, my receiver is old at least 5 to 6 years, I think it may just be time to upgrade it also.
Thanks for the help Ill see if this work

An older one. The first receivers with HDMI did not process audio they were video switching only. After that the higher end models processed audio via HDMI but the entry level models did not.

Nowadays all HDMI receivers process audio but this wasn't the case 5-6 years ago.

note the bold line in the specs below.

Receiver:
•built-in Dolby® Digital, DTS® & Dolby Pro Logic® II processing, for surround sound from DVD, VHS, and stereo sources
•5-channel amplifier (110 watts x 5, plus 230-watt (maximum power) powered subwoofer)
•Optimum Gain Volume Circuitry minimizes noise
•Wide Range Amplifier Technology for high instantaneous current capability
•H.C.P.S. (High Current Power Supply) Massive High Power Transformer
•192kHz/24-bit digital-to-analog converters for all channels
•adjustable crossover (40/50/60/80/100/120/150/200 Hz)
•SIRIUS satellite radio capable (requires SIRIUS subscription and optional SiriusConnect™ Home tuner kit)
•XM Satellite Radio Ready (requires XM subscription and optional XM Mini-Tuner package)
•XM HD Surround-compatible
•iPod dock included
•Audyssey 2EQ auto calibration (microphone included)
•5.1-channel audio input for connecting an SACD or DVD-Audio player
•HDMI switching capable (2 in, 1 out) with 1080p video pass through — separate audio connection required
•high-definition-capable component video switching (3 in, 1 out)
•5 A/V inputs (including 5 S-video and 1 front-panel)
•video output for TV (composite, S-video, component video, and HDMI)
•digital inputs: 2 optical, 2 coaxial
•full-size headphone jack
•color-coded speaker connectors
