win7 = no dolby digital audio - Roxio = yes!

[msongs]

boy we've been around the block trying to get win7 to play digital audio sound on dvds and no matter what we did using WMP we couldnt get any sound. so installed our Roxio 2009, downloaded the win7 compatible updates, and using their Cineplayer, got sound first try. Yay, now we can watch the dvds and hear them.

Have no clue why WMP wouldn't work tho.

Hi and welcome

Probably a codec, but who cares, there are tons better player apps. I have become partial to VLC od late because it natively plays anything I throw at it\

Hi,

I am engineer for Dolby and Windows 7 should definitely be playing back your DVD content ! Windows 7 has Dolby Digital + , which is backwards compatible with Dolby digital...

Dolby - Premium-quality surround sound to the PC in Dolby Digital Plus - Microsoft Windows 7

Please can you let me know what PC you have and what disks you have been trying ?

Thanks,
Marc

this setup gets no dolby digital...

hi, here's info. our computer is a custom built. I has 2 dvd drives, one is a recorder. It has onboard sound and an added sound card. A dvd with dolby digital audio and/or surround does not get sound using WMP that came with win7 64 bit home premium. Other dvds get sound fine via either onboard sound or added sound card. music cds also play fine. we did the settings changes and tests where you get the little beeps from each speaker and those were fine. the sound settings shows dolby digital is checked as enabled.

So we installed the Roxio Cinema player and got sound right from the start without having to change anything. Just WMP will not get sound.

our system only uses 2 channel stereo and not 5.1 or anything else.

the dvds we played were "Titanic" and "Almost Famous". I have just a few dvds really, and ones without the dolby digital logo play fine on WMP.

Hope that helps,

Msongs

Interesting... if your DVDs are commercial then they should all have a Dolby Digital soundtrack - Dolby Digital is the mandatory audio format for DVD. When you are playing any commercial video DVDs in WMP does a Dolby Digital Plus logo light up on the WMP interface even though you get no sound ?

Ill have a word round at Dolby and see if anyone knows of any particular issues or reasons why this is occuring. It would be good to know if anyone else on this forum has experienced the same thing too !

Btw the Roxio software will be using its own Dolby Digital Decoder rather than the Windows 7 built-in one.


Thanks,
Marc

Windows 7 has Dolby Digital +

Is that when you connect your components to a Receiver that has Dolby Digital ++

I didn't think it was built into Windows.

Where do you find the location for this?

 

[marclangsman]

Msongs - is your version of windows a retail one or an early beta ?

 

[msongs]

my version is full retail, not upgrade

got it at office max

 

[marclangsman]

@Msongs - sorry for the delay, still trying to get some info on why you're experiencing this is !

@RegHackr - Windows 7 should decode Dolby Digital off a DVD player through Windows Media Player. This means you can connect stereo speakers/headphones or 5.1 speakers to your PC and watch DVDs without any additional software. Previously you would have needed 3rd party software, a soundcard with the decoding on-board or you would have had to connect your PC to a home cinema receiver.

Yes,. I run Dolbly Digital thorough Media player my self.
I have a X-Fi Extreme 7,.1 channel sound card,. and my video card has HDMI out, so I.m good to go,.

I can't understand why someone with a Dolby Digital card would ptay it in stereo

There mising out on something great

 

[VanLazarus]

I have the exact same problem. I just purchased a Training DVD for Sony Vegas Pro 9 and there is no audio. I see the dolby icon in the lower left of WMP, but no sound!

Do you have onboard sound disabled in bios since your using a sound card instead?
