Nvidia GeForce GTX 460(GF104 GPU) supports full audio bitstreaming - Page 16

Zotac 460.

I don't wanna be the party pooper here, but they were talking about the 260 driver, not the card. I think you got those mixed up. The 200 series still can't bitstream.

Sorry if that's not what you meant.

Why don't those release notes specify that the 450 can bitstream? I asked Tom and he said it could, so, hopefully I won't have any problems, but, that doesn't make me too happy to see the "400 series" listed in the PCM category.

Yes, i suppose there is a confusion here

Samuri, i'm afraid this is my turn

(BTW i do still believe it's possible.)

I think we can be reasonably sure that the 450 will do, no?

Sure it wll, no doubt.

I can't see why it WOULDN'T considering it's newer than the 460. But those release notes don't specify the 450 on the bitstreaming part. That's all I was commenting on. Yea, I'm quite sure it'll bitstream fine. I can't wait for Monday to check it out.

I don't think that's very relevant. The most important thing would be the AV receiver he uses.
Which is it Rica?

I think the different results people have gotten, (for example Rica fully working, mine not working at all) are purely due to beta incompatibilities with a wide range of receivers...

About the silent stream bug, can anyone please spesify what exactly it is?

I got 2 problems with my GTX460 and the receiver.
One is, that it does not send constantly sound (even if it's just silence) so the receiver timeouts everytime I stop playing something with sound, and then sometimes it doesnt come back and needs a change of inputs to re-sync. I assume this is the silent stream bug u r talking about? or not?

The second thing is, that when I switch on my receiver, I get video on it but the nvidia hdmi audio is not enabled. And I need to take the hdmi cable off the receiver and back on it to have it enabled, which is a painfull process. If I just change inputs or something it doesnt work it's just like when switching it on... Any idea about this?

1) Yes, that's the silent stream bug
2) Yuck. That's an HDMI handshaking issue and most likely a driver bug. I get that kind of thing on my 4850 but usually changing channels fixes it. Is there a setting in the nVidia control panel to force the monitor detection? I was hoping to not have those kinds of issues when I get my 450 on Monday. Blah.

P.S. Tom corrected some misinformation in the PDVD10 thread. The 2xx cards can NOT bitstream. nVidia did, however, seem to add the ability to decode higher bitrates meaning that should PDVD10 allow it, they could stop downsampling on those cards. I don't know if that will happen or not but it's at least now possible.

Quick question.. just installed new Nvidia drivers, however, only getting DTS, Dolby Digital Plus and Dolby Digital under Encoded Formats / Supported Formats?

Is anyone getting DTS HD Master Audio or Dolby True HD coming up under supported formats?

EVGA GTX 460SC BTW.

Thanks

If it counts, streaming via PowerDVD without AnyDVD HD in place is working flawlessly, not one issue. And no silent bugs for me, the only thing I have is the initial start of sound is missing, due to no signal being sent. So its the delay of the reciverer kicking in, im awear this is "standard"... well as much as it could be lol.

mremulatro, You need to be sure it says NVIDIA High Defination Audio for the controller device. If that is not your sound device and you see Microsoft High Defination Audio. That is your problem. I had the same issue. Make sure you use the FULL driver from nVIDIA's website. Install everything.

I recommend the latest nVIDIA Beta for the 460, it has a nicer installation program and actually stats its installing the Audio Driver.

If you just got this card and plugged and played it, YOU MUST RE-INSTALL the driver from nVIDIA's website, you cannot drop this card in and be on your way. I had a 280GTX and was using the 258.96 driver already, I still had to re-install it once I put the 460gtx in.

Also, another tip. BE sure to disable any other sound devices, as the 460 becomes your new soundcard. Disable from Bios or Remove the Hardware.

This is happening to others with ATI cards too. It seems there's a hotfix for Win 7 you can try.

Thanks, however, you did not answer my question? Does it list the HD codecs under encoded formats in the supported formats tab?

Have a look...

I have good news especially for those who can not bitstream over their cards.
I've given it a go with my 460 and with new beta drivers.
PDVD10 2113.51.

Streaming Uncompressed PCM:

Original PCM is 96/24/2 and 96/24/6:

Output mode: "non decoded high definition audio to external device"

No downsampling, no downmix.



Decoding lossless formats to PCM:

Original THD/DTSHD-MA is 96/24/6:

Output mode: "PCM decoded by PDVD"

No downsampling, no downmix.

(ReClock downmixes in both cases to two channels even it doesn't downsample)

Here is the common SS:




EDIT: I will add this to PDVD10 thread after finishing my trials with Ati as well.

EDIT: Test completed; same results. I added this post to PDVD10 thread.

Same Nvidia drivers and PowerDVD here, however, no bitstreaming? LPCM is fine. What gives? EDID overide perhaps?

No i don't have any EDID override. I have a Denon 1910.

What is your AVR?

1909 mate. Are you showing the HD codecs under supported formats?

Weird.

Check out this if "audio enabled" :







_ _ _ _ _

Yup it's enabled. However, I'm not getting the HD audio listed like you.

460 HDMI out to AVR HDMI in
AVR HDMI out to HDTV HDMI in.

Is this your connection?


Before starting your PC, you are swithching on TV and AVR, correct?

My AVR settings:

Input device DVR,
HDMI 2,
Direct Mode.

_ _ _ _ _

Make sure that your AVR's HDMI Audio Passthrough setting is set to "AVR"/"Off" and not "On", "TV" or "Auto".

Thanks, but NA.

It's actually a Dell 30" monitor in my office, but yes that's the config. Going to try a clean install soon.

A standard HDTV resolution (e.g. 1920x1080) is required to bitstream.

Really? So no 1920 x1200 then? I'll switch to 1080p and see if the options appear.

ThanksTulli... that worked. Shame my screen does not do 1:1 pixel mapping so I get black borders. Oh well, looks like LPCM fo me.

on my 5770 I didn't have this problem.

I tried the fix but did not work for me. My problem also seems slightly different from the one described in the ATI thread. It has nothing to do with restarting the PC. It's just when I switch on the receiver, the nvidia driver detects it as a display device (and switches to it switching off my monitor as I have requested) but does not detect the audio part of the receiver so it keeps using SPDIF (that I normally use when using the monitor). It's only after I take the cable off and back on that it detects the sound device part of the receiver...

In the ATI thread they also specify that if they disable/enable the hdmi audio device the problem is solved, they just want to avoid even that process. In my situation this does not fic the problem either, that's why I believe it's a different issue and thus it's normal that the hotfix didn't work...

Thrylos,

Try to use two monitors:

DVI out of your 460 > HDTV HDMI in via DVI to HDMI cable
HDMI out of your 460 > AVR HDMI in via HDMI to HDMI cable.

Select your TV as your main display and disable audio for it and enable just for your AVR monitor.

This means you will seperate video and audio and you will most probably wouldn't live similar issues.

Just give it a go.

EDIT: No, forget it.
It's not possible with new beta drivers, sorry.

You could try an EDID override. That should force the Nvidia driver to take the full 256-byte EDID that the override stores in the registry for the AVR connection (instead of freely associating the EDID of whatever GenericPnP monitor you happen to have in the system).
