@huhn: I'm sorry but you don't get it. And yes it's not hard to search on google because it doesn't exist.
"7.1" is everywhere for marketing. But USB 2.0 has limited bitrate which prevent lossless 7.1. Maybe USB 3.0 could allow true 7.1 input but after a quick search, I don't see any.

i'm not going to do the math for usb. you can play a BD with PCM audio from a USB drive with absolute ease and the audio is a very very small part of the bistream it clearly possibile and there are 7.1 DACs.
and even if usb 3.0 is needed for what ever reason usb 3.0 is nothing new.

That is nonsense. USB Audio Class 2.0 devices over USB 2.0 can do full 7.1 and more. You get 480 Mbit/s of bandwidth afterall for USB 2.0, at 192 kHz/32-bit that would fit over 78 channel of audio. I know (professional) devices that support up to 64 channel. I've only used mine with up to 10 channel since thats the number of analog outputs it has, but I believe it can accept even more when you let it do the mixing.

What you are thinking about sounds like USB Audio Class 1.0

7.1 192kHz 32-bit PCM only uses short of 50Mbit/s of bandwidth, there is a lot of room in 480 Mbit/s for a lot of audio.

The Xonar U7 that huhn linked is a good entry-level device, full 7.1 at OK quality - not audiophile levels of course, but its pretty good (on the DAC level anyway, i don't care about other fancy features that some people might like).

But this is really quite off-topic for madVR now.

@huhn: Wow, when I was about to tell you you don't get it, I realised I was wrong. Arf, feel bad I had a wrong idea in mind all these years. I'll certainly try a 7.1 USB DAC in the next years.

By "apply", do you mean running Optimize and then trying to save the optimized settings? Or just trying to get madVR to change the display to the settings you created in CRU?

To get madVR to change the display to the settings I created in CRU.

I also tried the optimized timings and to my surprise madVR actually applied those. But the "optimized" are not so optimized from the looks of it.
They change the composition rate to 23.977hz for some reason and result in frame drops about every 2 to 10 min.

I have no damn idea why it actually succeeds to apply the worst possible optimized timings with all the newer drivers but fails to apply perfectly synced 23.976hz timings with zero frame drops like it did in previous drivers.

So on the first tab of Display Modes for your TV/monitor, you have (for example) 1080p23 in the list madVR can switch to, but when you play a movie it doesn't switch to the 1080p23 mode (23.976) you created with CRU?

While the movie is playing, which mode is shown as Active in the Custom Modes list?

No issue here with FSE 10bit.

Are you using AMD or Nvidia?

It does switch to 1080p23 but completely ignores the custom timing I set up in CRU that should result in 23.976hz.
When it switches from 1080p60 to 1080p23 it just results to 23.977hz like I didn't even create any custom timings in CRU.

Ok. Sorry I can't help, as I am using an Nvidia card - maybe someone else can comment.

Take the values you got from CRU and manually put them on the custom resolution tab of madvr (edit button), reset your pc or gpu and then let madvr automatically change the resolution. It should work this way.

Like I said before this doesn't work. When I apply those specific timings in madVR I get an error that says "Rejected By Driver".

Here's another approach you could try. Since you were able to complete customization, look at the details of one that gives you an acceptable time between frame repeats at 23.976 and write them down. Then delete the madVR custom resolution.

Run the CRU reset-all.exe. Reboot, and you should then see nothing other than the native standard resolutions in the OS Display Properties details.

Then create a new CRU entry in Manual mode using the numbers you wrote down from madVR. They should result in 23.976. Save it and reboot again. Then check Display Properties to make sure your new resolution is there and you can switch to it.

Go back into madVR, and your new entry should be listed as a standard resolution of 23. Type in "1080p23" (or whatever you're using) into the box on the first tab, and check to see if the "Valid" indicator is OK. Then play a movie and see what happens.

This way you're bypassing madVR custom resolutions altogether for 23.976, and still getting your optimized result. It's a pain, I know, but it should work.

That is exactly what I tried. For some reason this still doesn't work. While the EDID in madVR does show the created resolution with the custom timings correctly, when MPC-BE goes in to full screen and switched to 23hz mode the refresh rate still shows as 23.977hz and keeps repeating frames.

Behind the scenes the drivers still rejects those custom timings. CRU just doesn't show the error like madVR does when you apply them.

You can easily do 10 Channels and more using USB 2.0 audio interfaces. I use an RME UFX interface to feed:
2 Tweeter Channels
2 Midrange Channels
2 Subwoofer Channels
4 Surround Channels

Audio is being transported from Kodi DS via jackd's network portion, which works perfectly to connect Windows and Linux and being received from a Linux PC which does audio convolution.

Well, I'm baffled. I don't get exactly 23.976 either when I play a movie (slightly less in fact), and I initially get frame repeats every few seconds, but as I let the movie play the repeat rate gradually increases, and after 10 minutes or so it's less than one repeat an hour, and continues to improve.

I read in an earlier post that this is just a limitation of the measurement, and not to worry about what the OSD says if you can't actually see any repeated frames.

I have noticed the same but if I pause the movie and then resume my movie the stats change from 1 frame repeat every few seconds to every 15 hour or so.

It however doesn't matter what the stats say, for me the counter for repeated frames doesn't go up no matter what the "1 frame repeat every..." state and I do not notice any repeated or dropped frames.
