I’ve recently bought a new Sony receiver STR-DG720 and I’m having problems with sound coming from optical input.
All my mkv’s AC3 sound misses the center channel. Only the rest of the channels plays ok.
If I put the WD TV Live player on Stereo the sound comes ok. Also the if i set the receiver on 2ch the center channel mixes with the front speaker and i can hear it in stereo mode.
It sounds more like a problem with your AVR than the Live – the Live will pass through correctly mastered AC3 5.1 audio just fine.
You can post the MediaInfo on a file just to see, but I suspect you’ll need to check out your receiver and find out what’s wrong with the settings there (you also might try HDMI input if your receiver supports that).
I’m going to guess that’s a badly formed file (the language is Chinese which tends to make me think this).
Do this – try a known good MKV file (the best thing to do is to use Handbrake and encode something from a DVD or blu-ray but you will also need a ripper if you don’t have one. However, both DVDFab and AnyDVD have free trial versions you can use) and use the High Profile preset but change the output type to MKV and pass through the AC3/DTS tracks.
If this plays correclty (and I suspect it will) then you know the problem is with your file and not the Live (as it almost surely will be).
Well, that’s a different issue. Yes, the HDMI should (and does) carry digital audio. I don’t use the optical on any of mine, and I get 5.1 surround out HDMI…
BUT, the device on the other end of the cable MUST be able to decode it. If your HDMI is going directly to your TV, the TV must either decode or pass-through the signal to a decoder, or it’s not going to work.
My guess is you WILL need to buy another cable, albeit an HDMI one.
But first make sure your settings do say “Digital” and not the third choice (which outputs to Optical without outputting trhough HDMI, for those folks who don’t want their TVs to play the sound). If this is true, then by all means try another HDMI cable, preferably 1.4 certified (if you live near a Best Buy you can try out a very $$$ one and then return it if it doesn’t make a difference – or even if it does to get one somewhere else).
Then look to see if your AVR actually gets center channel sound from the Live – nearly all modern AVRs will tell you what channels they are receiving. If it says it is not receiving it try swapping the HDMI cables you do have, taking the one to the TV and putting it from the Live to the AVR. If neither then gets the center channel TO the AVR, then try the more expensive one from Best Buy.
You can definitely try, but it can still be the cable – different devices require different cables, and the Live IS particularly sensitive to HDMI 1.4 (we know that makes it work better).
After a reset to the player and then resetting the audio to digital the sound works now.
There you go. No problems with the cables.
My guess was the firmware because I’ve tested my PS3 when I purchased it with a cheap cable and the image keep disappearing. Then I’ve purchased some Sony HDMI 1.3 cables and all my problems disappeared.
The WD it’s using the same Sony cables. Believe me, PS3 uses lot’s more bandwidth.
