My BV-7 55 Cannot Decode Dolby TrueHD 7.1 Sound

32 replies

Hi Everyone,

Need some help, I brought the new MI-4 Ghost Protocol BD over the weekend and it seems all other languages works with Dolby 5.1, except the English Channel which is the TrueHD 7.1 doesn't work on my BV7-55 MK2.  There is picture but choking and no sound.  I am in the midst of getting service up and upgrading my software for the TV.  Anyone has the same issue?

 

Cheers

I don't believe Beosystem 3 can decode TrueHD.

Specs:

So even with SW update, it won't help?  Will B&O have a "fix" for this?

No, it's not a SW issue. We've discussed this many times in the past. Lots of people on here go on about how great the Beosystem 3 is at producing a great picture - it is - but it has its flaws. One of these is an inability to decode True HD, which is now the default audio format on a Blu-ray movie. I've argued in the past that this makes Blu-ray playback on an expensive Beosystem 3 TV (BV7-55 and BV12 are two good examples) as a bit pointless as half the reason for buying a Blu-ray is the uncompressed audio track.

People on here complain about negativity, but i'd be non-plussed and a bit disappointed if I bought a £15,000 B&O "top of the range" TV and found it couldn't even decode the default audio format on a Blu-ray disc. And, as I said above, it's not a recent issue. We discussed this about a year ago. You would have thought B&O would have upgraded the BS3 to support this format between now and then.

Without the uncompressed audio, you might as well rent or buy a 1080p movie from iTunes or similar. Why? You get a Blu-ray competing picture, but fairly similar audio. No point wasting your money on Blu-rays when you can't decode the audio track and are left with Dolby Digital. I stopped buying Blu-rays for that reason. They can cost £17 a disc, even discounted from Amazon.

Anyway, no, it can't be fixed. Decoding True HD isn't software-based. It needs support in the hardware.

...so what are we buying from B&O now a days......and why we pay top $$$$ for.  Disappointed...but...

Thanks Moxxey!

If you are using a bluray player like oppo bdp 95 it decodes tru hd and sends it as lpcm so then it is not a problem

I think that the blueray player in MK1 (which I have) can decode Dolby TrueHD, but not DTS-MA. The player in MK2 can also decode DTS-MA.

And I think the players must have very good decoders, nothing else makes sense for me, since the BS3 system cant decode HD.

And I agree, people would expect that one of the worlds most expensive TV's should be able to decode at least Dolby TrueHD and DTS-MA.

Maybe my rant above was a bit OTT. I'm in a bad mood today :)

But, yeah, I was annoyed having bought the Blu-ray add-on for my BV7-40 MKIV - which added nearly a £1000 to the cost - to find that it wouldn't decode the audio standard which is now present on nearly every Blu-ray (I can't remember if it's TrueHD or DTS-MA though, to be honest). I stopped buying Blu-rays at the end of 2011 as the audio standard wasn't supported on my Blu-ray BV7. Frustrating.

Would be interested to know if the MKII now decodes both TrueHD and DTS-MA. I was always told it was a Beosystem 3 issue and not the player itself as the player is simply linked to the BV7 via a HDMI cable! There's no decoding done on the player.

But he like me spent the extra cash getting a Blu-ray drive with their BV7, thinking it would support all standards. No-one at B&O/dealership advised otherwise :) We shouldn't have to then go out and buy an additional Blu-ray player simply to do something that the BV7 can understand (convert to PCM).

I have a BV7-55 without the built in BluRay and use an Oppo, but don't the specifications from the B and O web page specifically list True HD7.1 under Supported Audio Decoding Formats? This would match what Beolion posted "I think that the blueray player in MK1 (which I have) can decode Dolby TrueHD, but not DTS-MA. The player in MK2 can also decode DTS-MA."

SUPPORTED AUDIO DECODING FORMATS (FROM DISC)

Dolby Digital 5.1/EX 6.1/EX 7.1/Dolby Digital Plus 7.1/True HD 7.1., DTS MA7.1
DTS 5.1/ES 6.1
MPEG audio L1, L2
LPCM, 7.1ch multi-channel PCM
