Onkyo tx-sr875 no sound through hdmi.

How are your cable and cd inputs hooked up? Analog connections? Alot of receivers cannot send an audio signal from hdmi inputs to zone 2.

hi! i do have a couple of codes here for your Onkyo 2006, 2219, 2220, 2318, 2410,5002, 5018, 5073, 5074, 5075, 5076, 5077, 5078, 5079, 5080, 5081, 5082, 5084, 5085, 5086, 5087, 5130, 5131, 5140 hope this helps! goodluck!

The chances are that you have selected an incorrect sound setting or not switched it on, for the HDMI you are using. With Onkyo receivers each connection will have it own settings for video and sound. You just need to look in the manual as to how to select the settings.

try turning off HDMI Audio Out.

Not sure if this is your fix, but I had what I thought was the same problem. I played with my Onkyo quite a bit ensuring the correct assignments for HDMI, audio and all that stuff. Turns out I neglected to make sure the output devices were properly assigned. Many devices aren't default to output sound over HDMI. I changed the audio out settings on the cable box to HDMI and suddenly the Onkyo worked great. I know, I'm an idiot for not checking that in the first place, but maybe someone out there is having the same trouble as well.

My mistake, HDMI in is not routed to any other output but HDMI out

Hello, do the receiver inputs work with other HDMI sources? Thank you, Onkyo USA

Check speaker cables are in the right way as ONKYO amps have the conections side by side not up and down like most amps,also if you are useing hdmi leads go to the hardware set up in the menu and turn off the audio out for hdmi.
hope this helps.

Hello, the TX-SR875 does not support up-converting from component or S-video to HDMI. Is the model number correct? You stated the receiver is "brand new". This model is from 2007. Thank you, Onkyo USA

My configuration:
ZONE 1 (living room)
DishNetwork Dual Tuner DVR Tuner 1 [S-Video out] -> [S-Video in] ONKYO TX-SR875 [HDMI out] -> [HDMI in] Sony KDS-60A3000 rear projection TV

ZONE 2 (living room)
DishNetwork Dual Tuner DVR Tuner 2 [Composite Video out] -> [Composite Video in] ONKYO TX-SR875 [Composite Video out] -> [Composite Video in] Samsung AQUOS LCD TV

Problem:
ONKYO receiver stops sending video signal to my ZONE 1 Sony TV through the HDMI connection. ZONE 2 may still receive video. (NOTE: the issue might be related to the upconverter circuitry?)

Symptom:
I couldn't see any video, but I could hear the Tuner 1 audio through my ONKYO. An important clue is that I couldn't see ONKYO's on-screen display menu on my TV when hitting the [Setup] button on my remote. But, I could see my TV's Sony-based menus and display options.

Solution:
1. Put all ZONES in Standby mode using the remote. Hit these buttons on remote: [Receiver], then [Standby]. [Receiver], [ZONE2], then [Standby], [Receiver], [ZONE3], then [Standby]. You should NOT see any lights on the ONKYO except maybe one red led near the power button.
2. Pull the power plug out of the back of the ONKYO, and leave unplugged for 20-30 seconds. Turning off any power center it is connected to isn't enough. You MUST unplug the power from the back of the ONKYO for 20-30 seconds.
3. Reconnect the power cord to the ONKYO.
4. Using the remote, set ZONE1 to a video source known to be working. If you don't see video, try leaving the power cord off for a longer period.

I know it sounds too simple to work, but that's what brought the video back for me the few times the video stopped displaying. Hope it works for you.
