Bitstream or MPCM TrueHD or DTS HD over HDMI

Can anyone confirm that the ATI HD3650 on the FW or other Vaios can output Dolby TrueHD or DTS HD Master Audio as either an unadulterated bitstream or as a multi-channel PCM over HDMI to an A/V receiver?

I.e., is it possible to fully utilize the lossless audio formats on Blu-Ray discs?

 

That wouldn't be possible. Audio for that video card is standard 2 channel and 5.1 channel encoded DTS, DD support.

The 4xxxx series added 7.1 support and presumably LPCM support for outputting a bitstream / multi-channel PCM.

 

with the ATI HD 3xxx series it's not possible. as nystateofmind27 mentioned above the best you'll get is lossy compressed audio.

 

Thanks for the response.

To clarify, you are saying that the HD3650 will neither decode DHD or DTSMA and send it as MPCM over HDMI, nor send those formats as an undecoded bitstream for an AVR to decode?

 

the ATI HD 3xxx cannot decode HD audio and cannot bitstream HD audio.

 

Thanks...that sucks

 

as a consolation of sorts, Dolby Digital 5.1 tracks on Blu-ray are often encoded at higher bitrate than on DVD (i.e., 640kbit/s on Blu-ray versus 448kbit/s on DVD maximum).

devices that cannot decode DTS-HD Master Audio will extract the DTS core track which, again, is often presented at a higher bitrate than on DVD (i.e., 1.5Mbit/s on Blu-ray versus 768kbit/s on DVD maximum).

 

Any idea what it will downmix to? 5.1? And whether its a software or hardware limitation?

 

Dolby Digital and DTS supports 5.1 audio maximum. that's the best you'll get with the current Vaio FW with any Mobility Radeon HD 3xxx.

you are limited by hardware.

 

and there's no way of a driver update that could fix this? It's purely hardware and nothing can be done about it?

Really sucks that you can get HD video from a Blu-ray but are limited to a downmixed stereo audio signal which ends up being worse than you would get on a DVD.

Ah technology, a small step forward for man and a giant leap back for mankind.

 

a driver will not transform HDMI 1.2 into 1.3 or above.

you will get high bitrate Dolby Digital or DTS, both with 5.1 channels of audio, transmitted across HDMI 1.2 from the Vaio FW. if you want HD audio (in the form of eight channel LPCM) across an HDMI cable from a computer get one with the nVidia GeForce 8200/8300 chipset or ATI Radeon HD 4000 series of GPUs.

 

The True-HD and DTS-HD should works on laptops but i think 95% will not work ..
i never tried because i red this:there is written about dts-hd and true hd

if u want u can try:
for first windows must support proper HDMI connection
make sure u have got 1.3a ,b,c HDMI cable
make sure u vgot windows 7 or vista
make sure u have installed power DVD with latest update and set audio output on HDMI AC3 /DTS passtrough or PCM
make sure u have got sony receiver at least str-dg820 !
make sure u ve got AW series sony laptop

here is how toconnect to the receiver:

if will not work simply put bddisc into PS3 trough proper receiver and play

i heard that sound when i was at my friend's house its much much better than classic dts and dolby digital

 

not required; all HDMI-certified cables sold for home theatres will work.

 

mm no no old cables will not support true hd and dts-hd

take a look here :

- your table lists the HDMI protocols
- bitstreaming of HD audio requires the HDMI 1.3 protocol
- if your media player decodes HD audio into LPCM all HDMI protocols and all HDMI cables support the transport of up to eight channels of LCPM. since the Vaio FW (with the Mobility HD 3000 series of GPUs) cannot bitstream HD audio the best you'll get is high bitrate Dolby Digital 5.1, only the core stream of DTS-HD MA, multi-channel LPCM or two-channel stereo. in other words, with the Vaio FW equipped with an ATI Mobility HD 3xxx GPU, any and all HDMI cables made for home theatres are fine.

 

all right of course when FW dont support hd audio doesn't matteer of cable version
but i have AW Series...VGN-AW11S/B
i was thinking it could be some pins are not used or omething else ..my coleague in work told me it's about
thicnkes of cable hi purity tined! maximum length for good transfer is 3-5 m

and i have a question i just have powerDVD and BD advisor
and when i have connected (via hdmi) vaio aw11S/B to the sony kdl-40v3000 why bd advisor detecting wrong driver of nvidia and HDCP not supported? i will be unable to play any disc then ..
actually i have modified driver 182.06
hdmi audio is latest

 

there are three connector types for HDMI:

Type A - home theatres
Type B - very high-end displays (much greater than 1080p); not used yet
Type C - portable devices

anyways, possible signal degradation is only an issue if the HDMI cable is longer than 15 meters. for shorter distances any HDMI-certified cable is good enough.

the driver is not compatible with CyberLink BD Advisor. you may want to return to a 181.xx driver and hope CyberLink makes a patch to their product so that Blu-ray playback works with 182.06 and higher.
