From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Can you describe the issue? I don't use Discord (and I presume the problem might depend on what browser you use).
on discord on linux you can't screenshare with desktop audio, I think this might be already fixed in newer electron versions (but discord is closed source and has not updated their electron in a long time)
That absolutely sucks :| Thankyou for the detail.
As a workaround, you could use OBS and use OBS's virtual camera so Discord is streaming what it thinks is a camera, and set up whatever you want to share on your desktop through OBS.
I'm assuming this is a "dedicated app" (i.e. apt install discord). I was capable of streaming the video, but sound was a different beast. Audio streaming on discord was a no go. I was finally able to do it with pipewire and using discord-screenaudio

Jaysus, I wish this were a world where stuff like that wasn't necessary.
Uneducated question: what's the benefit of a dedicated client over running it in a normal browser?
Sorry for late reply. I just now noticed this.
The difference would be that a browser would likely have multiple web pages fighting for resources whereas the dedicated client would not have to fight over so many resources.
The OS has a dedicated task scheduler that alots cpu time to each process. Some processes get preferential treatment, but most processes started on user space ( i.e.double click UI icon) are just "normal" priority.
When a task scheduler hits on a process, that process can start executing whatever it needs to do. The problem with running discord in a browser is that the application is splitting its attention across multiple pages ( and probably other stuff ) instead of a single page.
Basically, it's faster to focus on painting a single canvas than it is to painting 3 at the same time.
I'm not going to discuss shared memory and separate processes or forking. You can goggle search if you want to know more about that.
I have discord installed from the flatpak. Screen sharing works but it doesn't share audio from the applications. Discord-screenaudio and web browser discord have been suggested to me but they don't work with unfocused push to talk. I've also tried xwaylandvideobridge but that didn't stream the audio either.
