a "7.1" device labelled "remap71", we can combine this with the Logitech audio output to mesh the two together (with no latency!)

Use the following command to create a new audio output named "SurroundCombine" and a corresponding sink called "SurroundComb"

pacmd load-module module-combine-sink sink_name=SurroundComb sink_properties=device.denoscription=SurroundCombine slaves=alsa_output.pci-0000_0c_00.4.analog-surround-71,remap71 channels=8 remix=yes

No remapping required, as we previously setup both audio outputs to display as 7.1!

Now set this as the default sink, and you should now have full 7.1 audio with two separate audio devices!

pacmd set-default-sink SurroundComb

And there you have it! You should be able to test your audio and have the speakers correspond correctly. I've tested this with a few different audio devices plugged in and as long as the audio device itself can decode what it needs to (in this case, my audio interface knows it has stereo speakers and my motherboard itself can handle 7.1 audio), this should hopefully work across a range of combinations!

Now, this will wipe the next time you restart your device, as Pulse sets defaults each time your device is reset. You can set this back up again by just re-entering the commands into terminal. Or, in theory, if you comment out the following line from /etc/pulse/default.pa

load-module module-default-device-restore

Then this shouldn't reload by default. Unfortunately, this doesn't work for myself but it does work for some people. I'm currently working on a bash noscript to run on startup to re-create this surround setup, but Pulse isn't playing nice. I might update this thread with the noscript if I do get it working though!

Hope this helps someone out and saves them a bunch of time, it took me AGES to figure this out. Thanks to the Linux community for providing answers on various forums on what commands to use for what! Here's some sources I used:

Linux is more fun than Windows to troubleshoot

Idk if it's just me or what but when Windows breaks, it feels like a slog repairing it. When Linux breaks though it's sorta enjoyable in a way to repair. Like I definitely prefer it when it just works but there's a weird sense of fun when you're looking through all the files and learning about systems to figure it out. Idk how to describe it really and maybe fun isn't the right word but there's definitely something better about fixing Linux. Anyone else feel this way?

Love hate relationship with Linux.

I have been using Linux since 2019 and every time I do, I always feel something is missing that's there in Windows.

I have an Asus Tuf F15 FX506HF (bought in 2024) and it uses Armoury Crate to control fan speed. But this software isn't available in Linux so the fans don't turn on AT ALL unless temps hit 80C. Also I'm currently in college so a lot of the software I use is windows only (stuff like Safe Exam Browsers, e-CAD software, WhatsApp Desktop) and I need to keep going to windows to do all these things.

But as soon as I switch to Windows I miss all the good stuff about Linux like how easy it is to install, uninstall and manage applications, the terminal and how everything related to programming just works in Linux (stuff like Git, PHP etc).

I'm really tired of going around and around and I really wanna marry and settle down to one OS but all the things mentioned above are dealbreakers for me. I've tried WSL and it's dogshit. I also tried VM but Linux just runs too slow in VM. Currently I have dual boot but everytime I need to access the other OS, I need to restart the whole machine.

Please help me choose and navigate.

Micro SD

I was told that SD cards / chips are not good for running Linux typically, however, don't USB thumb drives and what not have an SD card inside it? What is the difference of it being able to eject out of the thumb drive or not, is it a matter of being usb connection? Does it just have to connect to the computer via usb?

Is learning AWS and Linux a good combo for starting a cloud career?

I'm currently learning AWS and planning to start studying Linux system administration as well. I'm thinking about going for the Linux Foundation Certified Sysadmin (LFCS) to build a solid Linux foundation.

Is learning AWS and Linux together a good idea for starting a career in cloud or DevOps? Or should I look at something like the Red Hat certification (RHCSA) instead?

I'd really appreciate any advice

Have you encountered any virus on linux? And should we need antiviruses on linux?

While i was talking with someone on why he doesn't want to move to linux, i found that one of the reasons is that it doesn't have an antivirus

That reminded me of how dangerous linux viruses can be, as the root user is more dangerous than the admin in windows

However, it's rare to see a linux virus nowadays, but it's not impossible, so i wanted to see if someone has encountered one, and to see if an antivirus is needed or not

Let's not forget that running viruses on wine does exist and it's harmful

Looking for a good introduction to C for Linux native software.

Lately I've been wanting to get back into programming, but I wanted to try learning C and write desktop software and games. Anyone know of a good youtube series that walks through the basics and works with gtk, qt, or other type?

I can't believe it but i think i'm migrating to Linux on my main computer.

So a little background about me. Never ever used linux until 2-3 months ago. I was always a Windows user since i was a kid, used several ones including XP, 7, 8 and 10, 11 like every people out there.

And i was always frustrated by how outdated some systems of Windows are. File Explorer is a good example. UI feels outdated sometimes, constant freezing, especially when dealing with external stuff like USB sticks or CDs. It was bad dude. Bad.

I also dislike the general UI of Windows. It doesn't look great, especially after seeing that beauties of both Gnome and KDE.

So anyways i had a considerably old PC. Windows wasn't smooth so i was stuck. I had no idea what to do with it. Until someone told me to install Linux and it will be like a butter.

I said "okay..." but i had questions in mind...

Is it really smooth?
How compatible apps are?
What if something goes wrong? I ain't no coder after all
Wait, does linux users still code to install basic apps?

So on. I never checked the answers of these questions and jumped straight to installing Linux. The only distro i knew was Ubuntu for some reason so i also jumped straight to Ubuntu. The first thing that amazed me was how i can preview the OS in USB without installing it. Another thing that amazed me was how amazing the UI was. It was really good-looking, modern and smooth.

I had problems installing apps first but after discovering .deb, Flathub etc. it was no different from windows in terms of simplicity. Now i recently installed Kubuntu to try KDE, i loved it.

I think i'll fully migrate to Linux, even on my main computer, after realizing the freedom of it and that i can do almost everything Windows did on Linux. I was also shocked of the state of gaming in Linux. I thought it was impossible or somethin' but no y'all solved everything already and playin' games like on Windows. I'm not playing that much of a game except some strategy flavour but seeing Linux this advanced in terms of games, creativity, freedom, being open-source, literally everything, amazes me.

I thought i would experience problems every minute like constant freezing, random errors but no. Rarely? Yes but troubleshooting them is surprisingly fun. Lil' podcast or music in the ear and begin troubleshooting. Windows is a pain in terms of troubleshooting, tbh. I think it's like that because troubleshooting is pretty normal for Linux users so they found a solution for everything.

I side-loaded Kubuntu on my main computer already and i have a Win10 in my pocket in case something goes wrong, which i don't really suspect of.

I'm looking forward to see Linux's future because everyone is tired of outdated Windows, it's almost-monopoly state and money-grabbing policy of Microsoft. Open-source FTW!

I feel like I've gained some experience with the Linux OS. Like learning the basic commands, working with alternative apps, and doing some troubleshooting. Now I feel like it's a good idea to switch to something more advanced so that I can continue gaining experience. Is this a good idea?

My Experience with CachyOS – Smooth, Fast, and Finally the One

Hello everyone,

I wanted to share my experience with CachyOS, hoping it might help others in a similar situation.

My system specs:

Intel i7 12700KF
NVIDIA RTX 3070
Samsung 970 EVO 1TB SSD
32GB DDR4 RAM @ 3600MHz

It all started with Linux Mint. I gave it a try, but I had persistent issues with X11—especially when using dual monitors with different refresh rates. No matter what I tried, I couldn’t get it to work properly. I attempted Wayland on Mint as well, but that was a mess too (I'll skip the details—it’s behind me now 😅).

Then I moved on to Pop!_OS. While it was a bit better, I still ran into problems—mainly poor gaming performance and a few annoying bugs that I couldn’t ignore.

So I began searching for a long-term distro that I could really settle on. That’s when I discovered CachyOS. At first, I was hesitant about using an Arch-based distro, but I decided to give it a shot anyway.

The live environment ran flawlessly—everything just worked. I was especially impressed by how easy it was to set up my partitions (I have two 500GB partitions—one for Windows). I simply selected "Use a partition" during installation, rebooted, and I was in CachyOS.

From there, I installed the Bore kernel (which I read performs better on Alder Lake CPUs), and added all the software I needed—including the CachyOS gaming packages. I’m not exactly sure what they do behind the scenes, but they seemed useful, so I went for it.

Then I launched a game that previously ran poorly on Mint and Pop!_OS—and to my surprise, it performed just as well as it does on Windows. I tested more games and had zero issues.

I know it might sound silly, but I genuinely fell in love with this distro. Everything works smoothly, and the performance is fantastic.

Huge thanks to everyone involved in developing CachyOS and Arch Linux. I'm extremely happy with my new setup.
