Nvidia GeForce GTX 460(GF104 GPU) supports full audio bitstreaming - Page 17

Just to clarify, my setup is this :
1)DVI-DVI to Dell U2311h and toslink cable to Logitech Z-5400 speakers.
2)DVI-HDMI (with adaptor and then hdmi cable) to Harman Kardon AVR-255 (and from there on, to projector and speakers).

I use no1 as my main PC and when I want to "htpc" I switch on my receiver and I want this move to stop sending signal to the Dell, give signal only to receiver and use the nvidia audio to receiver and stop spdif. With the 5770 this was working flawlessly, because I had it set as a single display only and the receiver was set as display no1, so when it was switched on, it took priority over the dell. Similarly, I had the ati hdmi audio device as the default and the spdif as communication device, so when the receiver was ON the ati hdmi took over.

I have thought about using the hdmi on the GTX460 in case it makes a difference (I also thought I might be obliged to to get PAP working or any bitstream at all but this seems not to be the case) but stupid nvidia is using mini-hdmi in the reference cards and I don't have a mini-hdmi -> hdmi adaptor, and it's also pretty difficult to find one locally. I can get one from ebay but stil it would require several days to come...

Indeed i didn't mean that; i was using multiple monitors at the same time with previous WHQL drivers.
Not DVI to HDMI in later HDMI out to HDMI in of HDTV.

Never mind it wouldn't work with new drivers even if you had an adaptor.

But i must say that's very weird you don't have any adaptor bundled with your video card.

I have the GTX 460 hooked up via mini hdmi to my Onkyw 580 AVR out to Panny Plasma. My ATI card used to give me the problem of silent stream bug, but ATI has, since Catalyst 10.8 fixed the issue.

I purchased the GTX 460 because I wanted more horespower with low noise and for that it is great.... But the silent stream bug is driving me nutz.

So to recap. Latest beta drivers (260.63 - had same issue with whql drivers)
7.1 setup in Windows audio. Audio will play fine, but as soon as windows stops playing anything with audio, my AVR will loose the signal and give me that ever distinctive click noise.

Here are my screenshots of the HDMI audio properties

Yup, silent stream bug is there for current nVidia drivers according to previous posts. YEY. Can't wait for that tomorrow. I actually had grown used to it with my 5870 until they fixed it, so, I'm not AS bothered by it as I have been in the past. However, it'd be nice if nVidia fixed it like AMD did.

@Andy_o

Did you ever try James' anti-pop on an nVidia card? Just curious if he hard coded it for the AMD cards.

I did as soon as I got the 460 but no dice. Anyway that tool didn't fix the more annoying issue about it for me, which was losing some 2-3 seconds when pausing/skipping in exclusive mode.

Since I'm using RGB Full now instead of YCbCr and not gaming as much as I thought I would, I'm going back to the 5770.

Yea, I know it doesn't fix everything but it would help some people if it worked. I'll ask James to look at it. I think he has an nVidia card kicking around if I remember right.

I get my 450 tomorrow and for the games I do want to play on that machine, nVidia made a lot of sense since several of them use PhysX. It won't be my main gaming machine, so, I'm not concerned with having thie highest level of performance, but, if I can at least run some of my games in there it'd be nice. That's why I liked having the 4850 in there but it runs a bit warm. I'm anxious to see how well it performs in both bitstreaming and casual gaming. Should be fun.

My 450 should be making it's way from California some time this week. I hope that the drivers are out of the beta stage for these cards so I can get bitstreaming running smooth w/o updating drivers for the next 2 months.....

Is that normal? See my previous post where I only have LPCM, 16 bit and 24bit depths up to 192khz...

with my 5770 I had 16,24,32,48bit depths with up to 192 sample rates.

Any ideas on that?

I have the Onkyo 607, and while i get the silent stream bug, i never heard any click noise. All it results in is about a second of missing audio when bitstreaming, the handshake when outputting PCM is fast enough to not notice it at all.

I noticed that too, but it's not a real problem, is it? Also, I don't think the ATI offers 32 bit and 48 bit either. It offers 32 kHz and maybe 16 and 8 kHz sampling rates.

One possible but very unlikely annoyance out of this is that the ATI offers 88.2 and 176 kHz, and some people might wanna use exclusive mode with such music. It was only available via DVD-Audio though, and even then the 96 kHz rate was more popular. Even then you don't have to use exclusive mode.

Dunno, maybe my AVR is bad? it's the click you hear whenever you switch sound field format. For example when you switch from mono to stereo to Dolby PLogic, etc...
If you are playing some audio and switch the type of audio output it makes a 'switching click' I get this same click when audio drops and when audio plays due to silent stream bug...

Anyone else have Onkyo click noise?

Yes, James is. That's why wrote "ANTI-POP" in the first place.

Ok, nVidia gurus, I need help cause this ain't working well for me so far. Got the 450 and the driver installed. Running that machine at 1080p/24 (not 23). PDVD10 bitstreams fine. WinDVD bitstreams fine. ffdshow bitstreams fine. So, audio...golden.

Video, otoh, is not ok. I'll skip the black level discussion as I haven't even really gotten that far. Video in PDVD and WinDVD seems more or less ok. More testing is required as I do think I'm getting stuttering there, as well, but maybe not as noticeable. However, in ffdshow/MPC-HC, I'm getting WICKED stuttering. HIGHLY noticeable. I'm using DXVA/EVR CP and it's not helping.

Can someone who has everything working well on a 4xx card give me some detailed settings I can work on? I really am clueless with this new nVidia control panel. I don't even know if it's set to RGB or YcBR. I believe it's set to 0-255 but I'm not positive on that, either. I just don't know what to mess with to get this thing more stable.

On the plus side, WOW is this card quiet! But God help anyone who has a fusion case like mine cause um....yea, that ASUS card with the special cooler on it....it doesn't entirely fit. I kinda had to bend the top of the case ever so slightly to get it to slide on cause the cooler sticks up just a couple mm's too high. It's not a HUGE issue but the case is bulging a bit. sigh. But damn quiet, and PQ is phenomenal on the desktop. PQ in video needs some serious adjustment. I'll work on that once I know what to adjust. Bitstreaming...no issue there. That's perfectly fine.

All in all I like the card but I really want some help getting it set up and configured properly. Thanks for any suggestions you guys have!

Shuttering; with an niVida????

Yes, stuttering. And it's NOT making me happy. I'm recording shows right now so I can't play any more tonight, but, something is NOT set right for sure. I need to test PDVD and WinDVD again as I'm not sure if they were stuttering or not. I was mostly focused on bitstreamed audio when using them. But ffdshow/mpc-hc...that was bad. Very very bad.

The "pixel format" RGB or YCbCr setting is in the "Adjust Desktop Color Settings" section, under Display. Here, the only options are RGB (which is "full") and YCC. The dynamic range setting is in the "Adjust Video Color Settings", under Video. You'll have to choose to make color adjustments "with the NVIDIA settings" and then go to the Advanced tab.

About the stuttering... does it happen in any other config? Like, without ffdshow decoding, or with other renderers? I only used overlay and madVR. I think I did try EVR-CP for a bit and didn't see anything like that, but didn't test extensively.

With madVR in Windowed mode though, I did see stuttering in the video. Try madVR and its exclusive mode in full screen see if that helps.

Are you recording shows from TV?
If so you have to adjust screen resolution to 50 for PAL/ 60 for NTSC.
Sure you know, it's my stupid.

I'll check those settings later. Thanks.

I tried EVR Sync and EVR CP. I can't use madVR on that machine cause the proc isn't fast enough to decode. So I'm stuck with DXVA and one of the renderers that can handle it. I need to look at PDVD and WinDVD again and see if those are ok. I didn't have a lot of time for testing, and most of it I spent in mpc-hc/ffdshow trying to get that to work for my MKV's.

Not an issue for that machine, but, for playback that's definitely true. It's an HD PVR that records at whatever it gets for input from my cable box.

I'm definitely sure all those HTPC crowd needs a tool which automatically selects the source video's fps and auto-setup the resolution
I wish.
Sometime i forget to setup resolution to 50 (back) when i'm watching TV, my daughter warns me.

God that would be nice!

Seems to me very easy even i'm not a coder.
Refer to mediainfo and
if the source is 25 then go to blabla,
if the source is 23.97 then go to blabla...

MPC-HC already does this for us.

Really, i didn't know this, thanks.
But if i watch TV with DVBViewer or anything else?
And after if i wanna watch a BD with PDVD?
I need 50 first and 24 later.
And MPC can not be participant.

Yup there's an option buried in there somewhere. I don't use it myself (although I should) but it's in there.

OK, just leave it where it is, that's not one i desire.

Easy if you are coding the playback software. Not so easy if you are trying to implement it in all players. Basically, you would need to do one of two things:

1. Query an interface on the video decoder being used (all decoders would need to have that interface).
2. Write a video renderer that would replace EVR (and get all the players to use it). Like what Reclock does with the audio renderer.

vladd,

Why we have two options?

1) understand the source fps,
2) change the resolution whatever.

Why we need renderers?

Just what i do manually:

If i watch TV, i change the resolution to 50,
If i watch BD, i change it to 24.

That's it.

You could go another way with it. A loader for your favorite player (and your app could know what player it's loading based on the filename you name it as) that scans the file being passed in and sets the refresh rate before handing off the file to the actual player. ReClock works like this for audio. It replaces the audio renderer used by PDVD and TMT and calls the actual audio renderer as a passthrough. So, the loader app could be installed for players it knows and maybe an advanced option for someone to configure their own player in the same manner. Basically:

1) Rename the player's exe
2) Place a copy of itself in the player's dir and rename itself to the exe of the player
3) Pass the command line on through to the player after setting the refresh rate.

Media Info could be used to get the info from the video. For BD's it be more difficult but for files at least this would be possible.

Anyway, I've had a long long day of work, so, if this design doesn't completely make sense I can go into more detail if needed. But, it should be possible to do a passthrough "driver" of sorts. Is it flawless? No, but, it's at least possible.
