#StackBounty: #usb #audio #graphics-card #gpu #speakers GPU causing audible interference on new studio monitor speakers with USB interf…

Bounty: 50

Not sure if this is the right place to ask this, but here goes:

Background: I recently bought a new synth keyboard to use with my computer to record music. As part of this setup, I bought a USB audio interface (Presonus Audiobox USB 96), two Yamaha HS5 active studio monitor speakers and the requisite cables: two 1/4″ (instrument) to XLR cables and the USB connector that came with the USB interface.

I set it all up and everything was sounding great…until I fired up a game (Overwatch), at which point both speakers started emitting a low-medium frequency buzz at a low, but clearly audible, level. I tested with other games and had the same issue, but playing Spotify or watching YouTube videos was fine – no noise at all.

I tried various things to see if it would resolve the problem (I can elaborate if necessary), but on a hunch that it might be GPU-related (since it only happens when gaming and this would be the most GPU intensive work), I opened Task Manager and observed the GPU usage when loading the game. Sure enough, as soon as the game finishes loading, the GPU hits > 80% and the noise appears. To try and prove this was related, I dialled down the game resolution, and sure enough when the GPU drops, both the frequency and the volume of the noise decreases. With a more demanding game (Assassin’s Creed), the GPU hits 99% and the frequency is noticeably higher and louder.

If I run a game in windowed mode and minimize it, the GPU usage drops to 0% and the noise will disappear with it.

So… how on earth do I fix this? My GPU is a relatively new GeForce RTX 2070 and the motherboard is new also (MSI Z390 GAMING PLUS). I have tried every USB connector on my chassis, including USB3 and USB2. I also tried plugging the audio interface into my computer keyboard’s USB port to see if it would help, but the noise seems identical.

I’m really desperate to solve this, as I basically can’t play games now unless I use headphones and turn the speakers off, which kinda defeats the point of having them.

EDIT: if it helps, the XLR cables are these: https://www.pmtonline.co.uk/stagg-nac3psxmr-3m-balanced-male-xlr-to-stereo-6-3mm-jack-cable. They’re ‘balanced’ cables, which I was told would improve the sound by reducing noise, so hopefully, they aren’t the problem!

#StackBounty: #graphics-card #multiple-monitors #gpu #troubleshooting #pci-express GPU suddenly not being recognized in PCIe slot at all

Bounty: 50

The other day I updated to Windows version 1903. Things ran fine for a couple of days. Now when I turn on my PC my 2 monitors stay dark and nothing happens; I can see that the CPU cooler and GPU fans are running. LEDs are on too. Sometimes keyboard and mice don’t light up.

Relevant Parts

CPU: i5-6600k

GPU: GTX 1070

Motherboard: AsRock Z170M Extreme4

Dual monitor setup: 1 HDMI, the other mDP/DP.

Things I have tried

  • looking in Event Viewer for any relevant information (nothing that I could identify)
  • switching to motherboard output (HDMI) allows me to boot and I have visuals on one screen
  • using this I was able to access the UEFI/BIOS screen:
    • it says the PCIe slot that the GPU is physically plugged in is empty
  • tried switching PCIe slot, same issue
  • I cannot rollback the update because I deleted the Windows.old files

The weird thing is that initially, I tried restarting my PC several times and once or twice I was able to boot with my GPU, but only if the DP cable was unplugged. After another restart, I have been unable to replicate this.

I have not tried clearing the CMOS yet.

#StackBounty: #drivers #nvidia #graphics #xorg #gpu Using P104-100 GPU on Ubuntu (as single or second GPU)

Bounty: 50

What I have:

GA-B250-Fintech motherboard

Ubuntu 18.04 (but I’m ready to reinstall to any version if it will work)

$ uname -r
4.18.0-18-generic

And P104-100 video card.

$ lspci | grep NVIDIA
01:00.0 3D controller: NVIDIA Corporation GP104 [P104-100] (rev a1)

gcc --version
gcc (Ubuntu 7.4.0-9ubuntu1~18.04.york0) 7.4.0

The problem:
every time I install nvidia drivers, Ubuntu stop loading. Usually with message:

started user manager uid 121.

I plug out P104-100 and plug in GTX 1060, this works correctly:

+-----------------------------------------------------------------------------+

Then I tried plug in P104-100 as second card using another slot, and Ubuntu stops loading: freeze with message

Started GNOME Display Manager.

P.S. Using lshw -C display I found both cards have
physical id: 0
Can it be a reason?


Question:
How to install both cards on Ubuntu?
I think if I successfully install P104-100 as single card the same solution could be for installing both of them.


P.S. I found some solution about editing xconf for using on multiple GPUs: for example.
But it did not help.

#StackBounty: #drivers #nvidia #graphics #video #gpu Video quality problem with Nvidia

Bounty: 50

I have a GTX 1060 6GB GPU on my desktop connected to a 4K monitor. There is no image quality or resolution error, but when there is fast movement in a video, the image becomes pixelated.

I installed the driver and CUDA toolkit 10.1 from the official website.

With a Radeon GPU on the same machine, the video plays smoothly with crisp images.

Do you have any hint what can be the source of this problem?

#StackBounty: #laptop #graphics-card #hdmi #gpu #amd-graphics-card How is it possible to find out the HDMI version on windows?

Bounty: 50

I would like to know, if my laptop can output 4K/60Hz to the TV, using the HDMI cable. Unfortunately I have no idea where to find this out.

I’ve found some similar questions, but the answers were not generic, they just answered it for that specific computer.

My laptop is: HP Notebook – 15-ay108nh

The CPU is i5-7200U, which has HDMI 1.4 (4K 24Hz ?), but it shuld be able to output 4K 60Hz on the display port.

The GPU is: AMD Radeon™ R7 M440 Graphics (4 GB DDR3 dedicated). I was not able to find out, what kind of HDMI output does that have.

The laptop has only one HDMI output, but I don’t know if it belongs to the integrated or dedicated GPU.
