Hi everyone, im new to the forum, and appreciate any help anyone can give here. Ok, here' my situation: Last year I bought my dad a Panasonic Blu Ray HTIB system....it works great for his needs, but there was always one problem: With his Directv playing through the HTIB, his sound and video (lip sync) was often out of sync....i tried everything and eventually learned that it's basically a problem directv has with certain other components and there is no real fix...so, he just dealt with it...

Fast forward to now....I finally got tired of it when visiting him, and decided to buy myself a new AV receiver and give dad mine which i hoped would alleviate the sound sync problem since his Directv would now be input through the receiver and not the HTIB....so, i rewired the speakers to the receiver, and input the Directv to the receiver.

Presto, it works, and there have been no lip sync problems...but here is the new problem, caveat:

The receiver is an older Yamaha RX-V363...so while it has hdmi inputs, the receiver will not decode and output the audio via HDMI alone...you have to run a separate optical cable....ok, fine. No problem with the Directv box.....hdmi for the video, optical for the audio, receiver decodes and outputs fine..

BUT....since the Panasonic blu ray player was originally a HTIB...there is no digital audio OUT...so, i can't decode and get the audio from the blu ray to the receiver....when i tried leaving the blu ray hooked up via hdmi to the receiver and running an optical from the tv.....the receiver only showed as playing stereo, or 2 channel audio..

So, is there any way to resolve my problem without either buying my dad a new blu ray player that does have digital audio out, or a different receiver that will decode and output the audio via hdmi?

I was hoping that if i connect the blu ray player directly to the TV via HDMI (the tv is a 2009 or 2010 panasonic lcd), and then go optical audio out to the receiver, THAT will do it. Does anybody know if that will work? Or of any other solution with those components?

Thanks.

The output of the TV is always limited to stereo. Blu-ray players are pretty cheap these days. That's likely your best option.

Ok...I have seen some posts in other threads saying they have gotten 5.1 output from their tv's optical out. Is that only if the TV has its own decoder?

TVs pass DD 5.1 from sources they acquire themselves using an off-air antenna or smart tv app. A few will pass DD 5.1 from external devices. And almost none will do DTS. As you are connecting an external device to the TV, you are limited to stereo. Panasonic sets definitely have that limitation.

This. The HDMI conection starts with a handshake between the two devices in which the TV tells the BD player that the TV is only stereo. Knowing this, the BD downmixes to stereo, and that downmix is what the BD out[uts everywhere and is OP is hearing.
