HDMI is fine but no audio through receiver

by tbeevers / September 4, 2008 3:03 AM PDT

I've got a Motorola DCH3416 HD DVR from Comcast and having a heck of a time getting video and audio. I'm running a HDMI cable from the DVR to my Samsung HDTV. I'm then running an optical from the TV to my Sony receiver. I can hear sound from the TV speakers but nothing through the receiver. I've also tried component cables along with audio cables and the same problem.

The above tells me that audio is going to the TV via HDMI but not from the TV to the receiver. The interesting thing is, I had a Series 2 TIVO unit hooked up before the HD didn't have HDMI so it was all component cables but the audio worked fine through the receiver. I thought it might be a bad box from Comcast so I'm on my 2nd one now but same problem.

Any suggestions?

HDMI Issues

Did you attempt to run the optical cable from the DCH3416 to the receiver to eliminate a cable box issue. Also, check the av settings on the tv to assure that you are setup properly for using the audio out connection for optical.

I thought I had tried this option but apparently I didn't. I followed your advice on running the optical from the DVR to the receiver and it works beautifully!

Thanks for your help.

No Audio from HDMI

I have been looking to buy a new A/V Receiver and found out that the Sony 720 model doesn't pass audio via the HDMI. My STR-K750P is old and only had RCA output. With my Xbox 360, DVD player, and cable box I needed to upgrade. Look at user reviews and other forums and you will find the same. Make sure the HDMI output will carry the audio. I'm not sure what model you have.
