Hi, I have a problem when using the nVidia Pure Video decoders and watching a ripped DVD (vob files). I get no sound. If I look at the nVideo decoder details, I can see that it is decrypting audio as the bit/rate bar changes. I have set the video and audio codex as nvidia in Setup->Movies->Movie Player. I have done a speaker test/calibration using the nvidia pure video when it is playing without any vob movie audio and I get the white noise etc when it checks if a speaker is working. I have set the audio renderer to nForce audio, DirectSound:nforce audio, default direct sound and default waveout device. No change.

If I watch the same vob in media player I get sound and it works fine.

If I uninstall the nvidia pure video and use DScaler for both video and audio it works fine.

Any ideas what might be causing this?

Cheers.

Ok, just figured out that the vobs use the DVD config in the setup instead of the movie section. Still same problems though when I pick nvidia purevideo audio decoder. No sound.

If I just switch it to DScaler it works fine, even without installing purevideo.

Hi,

sorry no. I just can confirm this issue. I also have no sound with PureAudio on DVDs. But it works outside MP without problems using graphedit...
Also MyTV is set to use PureAudio and it works. So, not much help, but a confirmation.

ah thanks for the follow up FlipGer. I was thinking I had something strange going on with my setup.

...Just had a thought.

I do my Windows Updates manually -- Ive not ran them this month...maybe a connection ?

It's all ok, now!
Update'd something in configuration and now works like a charm, too...
