i would like to record my monitor-sound (e.g. musicplayer) and microphone with audacity 2.4.2 under pop!_OS 21.04. i am using the u-phoria umc202hd (i use the third soundcard U192k).
do you know a way to record monitor sound and microphone with audacity simultaneously on linux?

That is two separate operations. In Linux, it is possible to use loopback recording to get a copy of what is currently going out the speakers. Start looking here:

On Manjaro Linux.
Running Android Studio 3.6.3. Everything works great, but when I try to launch any emulator I am getting this error:
Emulator: createOrGetGlobalVkEmulation: Warning: Vulkan 1.1 APIs missing from device
I'm not having any driver issues outside of trying to use the Android Studio Emulator.
Studio SDK's installed:
Vulkan driver's installed:
I have Radeon's Vulkan mesa driver installed in manjaro. I also have virtualization enabled for processor in BIOS.

You can work around it as indicated here https://stackoverflow.com/a/59715169/1796802 :
Create the file ~/.android/advancedFeatures.ini
(for Windows users path should be C:\Users\Dane\.android\advancedFeatures.ini) with the following content:
# Here's how to disable Vulkan apps to talk to the emulator.
# Add the following lines to ~/.android/advancedFeatures.ini (create this file if it doesn't exist already):
Vulkan = off
GLDirectMem = on
I have a NVIDIA Grid K2 GPU allocated to a virtual server running Ubuntu 14.04. To reinstall the proper drivers after an automatic kernel update I ran sudo apt-get update followed by sudo apt-get install nvidia-current.
Now I cannot get CUDA 7.5 to work any longer. If I run the deviceQuery sample I get the following message:
CUDA Device Query (Runtime API) version (CUDART static linking)
cudaGetDeviceCount returned 35
-> CUDA driver version is insufficient for CUDA runtime version
Result = FAIL
This is the output from sudo lshw -c video

I solved this issue with the following steps using the hints from the installation guide:
Uninstalled the packages that I had mistakenly installed by running sudo apt-get --purge remove nvidia-current.
Uninstalled CUDA 7.5 with the command sudo /usr/local/cuda-7.5/bin/uninstall_cuda_7.5.pl
Restarted the server using sudo reboot
Installed CUDA 7.5 by running the downloadable .run file and following the instructions.
Checking that everything works by running the deviceQuery CUDA sample.
I am trying to run a cuda application on an Ubuntu 10.04 system with a GeForce GTX 590.
I'm using the 295.41 drivers. I have set up 3 other systems with this code and all have worked. Two of them had GT 640s and one had a GTX 480 (or 460 - I can't quite remember). I have run cuda code on this machine with the same hardware before but it has since been formatted.
I get the invalid device ordinal error when I run my code and also when I run the SDK examples. I set up this machine with gentoo and got this error - I thought it could have something to do with the OS so I installed ubuntu and have the same problem. I can't think of what else to try. Does anyone have any suggestions?
Below is some output that could be handy.

Edit: When I had this system working I was using a 64 bit os and the 64 bit drivers. I am now using a 32 bit os and 32 bit drivers.
Another Edit:
Thanks very much Przemyslaw Zych. You helped me solve the problem.
I had to blacklist Nouveau by doing the following.
Add a file in /etc/modprobe.d called blacklist-nouveau.conf (just the .conf ending is important) and in that file put the following two lines.
blacklist nouveau
options nouveau modeset=0
As instructed at the following guide
ftp://download.nvidia.com/XFree86/Linux-x86_64/256.44/README/commonproblems.html
Problem solved :)
As Przemyslaw Zych suggested there was another driver using the GPU (in this case nouveau).
To use the nvidia driver nouveau must be disabled. The procedure is listed here - ftp://download.nvidia.com/XFree86/Linux-x86_64/256.44/README/commonproblems.html - and I will summarise it below.
Create a file in /etc/modprobe.d called blacklist-nouveau.conf
Add the following two lines:
blacklist nouveau
options nouveau modeset=0
Then reboot the pc. This should prevent nouveau from loading and allow the nvidia drivers to be used.
