madVR - General discussion thread

[mclingo]

you are probably right, i'll pickup something better when I have the cash if its easy enough to do using DISPLAYCAL

I did.

Thanks again

Hi, my email account got hacked so I had to shut it down, i'm using this as a templ account, anyone know how I can get my email changed on my main DOOM9 account, there seems to be no support section anymore.

Is any of you having issues when playing a movie using PotPlayer+MadVR? After the last W10 updates from yesterday (ver.1903) MadVR crashes when Potplayer starts.

[QBhd]

It was fine for me last night... I'm sure I got this week's update

Well, I installed the last version of MPC-BE and configured with MadVR and works fine, it seems somenting related with Potplayer =/

[Klaus1189]

My advice, stay with MPC-BE

I've noticed that with madVR, I have background sound. It's like coil whine, except it is real sound produced by computer.
It means if I use another soundcard that the HDMI (nVidia 1060), for example optical from motherboard, I still have this background sound, and like people mentioned in the past, with NGU, it is amplified.
Sound is really coming for speakers and not motherboard. So strange. Without NGU, it is weak but it is here. I don't have that with mpv ou a browser or even powerful games !

and how is this opotical device powered?

it's impossible to create audio from a video renderer but is is not impossible to fill the signal with dirty power that creates hearable artifacts in speaker.

[Asmodian]

madVR is an unusual power load on GPUs (very spiky) so some GPUs that do not normally whine will when running madVR. Your issue sounds similar. You must have some electrical crosstalk between your audio channels and your GPU.

[huhn]

this is a pretty far spread issue i can easily make a recording with that using different soundcards one that totally fixed the issue too.

the AVG user doesn't care about stuff liek this they only care about loud...

[pirlouy]

I never said the video renderer created sound by himself. I have no doubt there's no sound code in madVR.
But still I'm surprised how a GPU can create disturbance for something which does not seem that connected (optical soundcard from motherboard).
And I'm also surprised the noise comes only with madVR. I'm certain you will say madVR code is perfect, but as I don't have this sound with other applications (including GPU stress tests), I have my doubts.

I'm not sure to understand this sentence, from my post, we can see I care about sound (and even hardware). I care more about sound that image. I don't use madVR that much, that's why I did not complain before.

is the amp DAC power by USB?

GPUs can do what ever they want it it should never effect audio everything else is a hardware flaw.
coilwhine on a GPU is a hardware flaw the program in question has nothing todo with that.
hearable noise in the audio signal is the same.

why would you think i mean you with that only saying this is not as rare as it may seem.

[clsid]

It is called electromagnetic interference (EMI) and it's a pretty common issue. Google for that to get tips on how to reduce/solve it.

As I mentioned before, madVR is a very unusual load on GPUs. A GPU stress test is nothing like madVR. Also, how would 'imperfect' code in madVR cause random noise on your soundcard that changed with the resize algorithm used? And only on your system? It makes a lot more sense that the exact behavior of the GPU power draw, which changes based on the algorithms used and is unique to madVR, is interfering with the audio device.
