🚨 HUGE: Spotify Lossless/HiFi is LIVE on the Linux Desktop Client (PipeWire Proof Inside!)

Hello r/linux,

I have some exciting news for all Linux audiophiles! It seems **Spotify has quietly enabled Lossless (HiFi) audio streaming on their native Linux client** without any official announcement or client update.

I confirmed this via the audio pipeline, and the results clearly show a CD-quality stream.

# 1. Discovery and Client Details

* **Spotify Version:** 1.2.63.394.g126b0d89 (Copyright (c) 2025, Spotify Ltd)
* **Operating System:** Linux Mint 22.2
* **Audio Server:** PipeWire (Running via pipewire-pulse)
* **Prerequisite:** Spotify Premium subnoscription (The Lossless option appeared under the quality settings.)

I noticed a new **'Lossless'** option in the Audio Quality settings, situated right below 'Very High.' When this setting is activated and playing a track, the audio output is immediately upgraded.

# 2. Technical Verification (The Proof)

To verify that the client is actually streaming at a higher quality than the standard 320 kbps Ogg Vorbis/AAC, I checked the output format reported by PipeWire using the `pactl list sink-inputs` command.

The crucial finding is that the audio stream is running at **44.1kHz**.

# 🔑 Key Output Lines (From pactl list sink-inputs)

サンプル仕様: float32le 2ch 44100Hz
形式: pcm, format.sample_format = "\"float32le\"" format.rate = "44100" format.channels = "2" ...
プロパティ:
application.name = "spotify"
application.process.binary = "spotify"
media.name = "Spotify"
node.rate = "1/44100"
media.class = "Stream/Output/Audio"

What This Means:

44.1kHz (CD Quality): This confirms the stream is using the CD-standard sampling rate, a hallmark of lossless quality, and is not the standard 48kHz used for most compressed streams and general PipeWire mixing. Float32LE: Spotify is utilizing a high-resolution, 32-bit floating-point format internally, which is a best practice for maintaining audio integrity and avoiding digital clipping before the DAC. Server-Side Switch: Since there was no client update, this feature appears to have been rolled out via a server-side feature flag (a "secret switch") to select users/clients.

# 3. Call to Action

If you are a Premium user on the Linux desktop client, please check your audio quality settings now! Can anyone else confirm this behavior, especially on different distributions or with ALSA/JACK? This is a massive win for the Linux desktop audio ecosystem!

*(元の投稿者による日本語コメント: これまでLinuxでロスレス再生は非常に複雑でしたが、PipeWireのおかげでスムーズに実現できています。この発見は本当に嬉しいです！)*

I'm Out Of The Loop. What's the deal with DHH (Omarchy) and Framework vs Gnome, Debian and other projects?

I'm curious to know why there is so much drama among these Linux folks, at least on social media and communication channels.

* I didn't know anything about Hyprland, but it seems that its main developer is quite problematic and authoritarian, calling users on Discord or GitHub idiots at the slightest provocation, or for not having the same knowledge as him.
* I've heard something about Omarchy, a distro created by DHH based on Arch + Hyprland. I know he's a controversial character, very much cut from the cloth of the typical wealthy tech bro.
* Finally, I've heard of Framework, a company that manufactures Linux laptops.

It seems, if I'm not mistaken, that Framework decided to donate to and support Hyprland and Omarchy, among other projects, and there have been communities such as Gnome and Debian that haven't had a good opinion of this? With some in Gnome thinking of rejecting the donation and Debian removing Hyprland from its repositories?

Meanwhile, what I've seen on social media is DHH attacking these projects as much as he can and integrating himself into circles that link Linux with ideology, from a conservative or right-wing/far-right point of view, starting to criticize these projects for being leftist, and saying they criticize him “for calling attention to the hypocrisy of the left, which generates defensive overreactions,” and “I was blissfully unaware of just how nutty things had gotten in much of Linux land, and didn't realize GNOME had been fully captured.”

**Captured by who? What is all this shit? What's the context suddenly for all this? Was Framework already a huge donor or this is just overreacted and no problem?**

I'm perplexed by how so little part of the community can make such a big fuss and be able to turn on the shit fan over so many people over so many projects (Gnome, Debian...)

Fedora KDE why haven't i discovered this OS earlier

Been an ubuntu/pop os/windows on and off user for the past few years but fucking hell fedora kde blows them all out of the water. Its super fucking snappy and everything just works this feels like an os from the future. Bro the websites don't even load they're just there almost instantly. This shit is crazy, it literally feels like i got a brand new computer. The bluetooth also fucking works!

I've been really missing out all these years, i could have been using this instead. How come this is not recommended more?

with AI, Linux is actually more accessible than Windows

Imagine you don't know how to do something on a computer. You ask your favorite AI "how do I do this and this" in Windows you get "click here and there" and in the new release of Windows the UI might not be there...

On the other hand in Linux you get mostly command line command generated by the AI and you just directly copy-paste it.

Which has the effect that you actually control your computer with natural language (English) - which you type to the AI and get precise commands :)

Xubuntu website got hacked and is serving malware (trojan)

Just be aware, Xubuntu.org got hacked and their download button tries to download “Xubuntu-Safe-Download.zip”, that seems to include a fake TOS and an EXE, and Virustotal confirms malware (a Trojan) inside of it. Seems someone’s trying to get noobs from Windows that could be interested in Linux (more so now because the Win10 EOL)

Hope the people at the Xubuntu project and Ubuntu/Canonical can take fast actions, but this seems has been up for 6h now, going by the first people that noticed. Having this vulnerability up for 6h shouldn’t be OK.

Linux is pretty cool so far

I've been using the Linux Mint OS to replace the now unsupported Windows 10 OS on an old laptop that certainly won't have a single bit of processing power to run Windows 11. So far, I'm in love, and I am planning on using said laptop to test things like electronics. And I gotta say.. it wasn't and really isn't what people are saying it is, it's not as code-y or hard to use, like they were saying 10 years ago. It honestly feels like a brand new cheap (it's running on a HDD, yes I have a replacement) laptop with a slightly crap battery life, but still feels utterly brand new, regardless. Thanks, Linux community for another light shining on an old laptop. Very cool.

Tron: Ares Runs on Linux! (Movie featured accurate CLI and and systemd commands)

Saw Tron: Ares today and I was happy to see a movie version of "Linux" OS being featured. I enjoyed the movie and seeing one of the characters write out the command:

'sudo systemctl stop'

Made me appreciate that the team didn't phone it in on the command line stuff. Their very quick visual intro to "training" neural networks was a nice addition also. The movie surprised me in good way and it was a nice nod to those with a background in Linux, software engineering and deep learning!

Linux > Windows even on new & powerful hardware (ThinkPad E14 Gen 6)!

I got a Lenovo ThinkPad E14 Gen 6 (Intel Core Ultra 5 125H, 32 GB RAM, 1TB nVME SSD) system last year, and while I was already a full-time Linux user, I decided to give Windows 11 a try. Surely, with that kind of processor and RAM, the experience would be pretty smooth, right? Nope, I was proven wrong. While things were fast and snappy initially, within a week I started seeing graphical glitches here and there. The Explorer for some weird reason kept crashing, the entire desktop crashed and came back up multiple times right after waking the laptop from sleep, and a lot of other things. These glitches got so bad that I had to restart my PC every 2 weeks just to keep them at bay.

As I said, I was already a full-time Linux user. I run Arch Linux on both my servers and they've been working amazingly well for the last 3 years, so it was my preferred choice when choosing which Linux to use. For GUI, first I went with i3 (created all the workspaces and stuff), and lately I have been trying out KDE just because I can. Regardless of the desktop environment / window manager I use, Linux has been rock solid and stable on this system. Most of my games (I only play single-player story based ones) run at-least 10% better on Linux than they ever did on Windows, that too UNDER EMULATION!! Lastly, I'd like to mention that, as crazy as that sounds, the battery life has actually been a lot better on Linux. I simply used TLP to configure platform profile and CPU governors and stuff, and that was enough. So, my verdict is that Linux is not only an excellent choice on older computers, it's also a good choice on new performant hardware.

TL:DR; Got a new ThinkPad E14 Gen 6 last year (Intel Core Ultra 5 125H, 32 GB RAM, 1TB nVME SSD). Tried Windows 11 on it, and the experience sucked. Wierd graphical glitches, desktop crashing, explorer crashing, etc. Had to reboot atleast once every 2 weeks. Switched to Arch Linux, and experience was so so much better. No more lags, no crashes. Just pure performance and stability. Also, battery life on Linux >> Windows (who would've thought?!)

Linux - all you need to experience the beauty of your pc

So, like yesterday I Installed Linux, more precisely, Atomic Fedora by the name of Bazzite, well installation itself wasn't that bad, since I followed a simple tutorial for it and the moment I finally got it I started personalizing it for my own liking, I was actually amazed by how clearly in setting it was all described, explained and it was quite a simple thing to do.

Of course, how someone new with Linux wouldn't face problems - for me, who's not so good in such stuff, was quite difficult to get the hang of "sudo" , flatpaks, how stuff works and all that. It was quite confusing, but with a little of googling, community help and some YouTube videos I understood it better! Which is what I'm very proud of.

But the question why? Why did I abandon the “Titanic” that had just hit an iceberg? The simple reason I quit and deleted windows partition, the moment I fell in love with Linux was because of all the crap they have there. When I saw my laptop breathing after getting rid of those damn windows I understood that almost any hardware can run Linux, which I was amazed with. I am a person of gaming and usual daily usage of pc, so I dont really mind some apps not working or something.. Im happy with my spotify, brave, steam and discord. Its literally all I need for my PC for now, also some performance apps like fans control according to my CPU temps.

Im honestly happy with Linux.. I booted up a game and I was adored by the smoothness of my experience. I felt a joy that I barely felt on windows when everything works precisely without all the bloatware.I really feel like a weight has been lifted off my heart. At first.. few years ago I tried Linux Mint. I wasn't this satisfied like I am now since all the distros there are, are just like your reflection of who you are. It wasn't my taste so I didn't liked it. But this distro I use now somewhat relates to me on deeper level, I know it could sound silly, but I just feel so comfortable like at new, comfy home.

I was feeling so much pleasure and happiness I couldn't hold myself to write all this and actually say thanks to people who created this distro, to person who created Linux itself. Its life changing for someone who wants to live a bit differently!

Thank you all for reading! 🫶

I am quite spoiled...

I have a few machines which are all SSD with modern CPUs. Just one of them has a 5.25" spinning disk for things like ISOs and other static data, everything else is solid state. Standing up a KVM vm takes 10-15 min, a bare metal install takes 30-40 min.

With that said, I performed a bare metal OEM install of an unnamed distro to an older HP i3 with 5400 rpm disk machine recently. It took just over 2 hours. After the fact it turns out that the HDD was on it's way out and probably throwing a bunch of errors under the covers, but holy cats - 2 hours!

Fast hardware is nice, I'm spoiled by it, and I like it.


[ Edit: 5.25 should read 3.5 \]

Ironshell Gui SSH

I'm not sure if I'm doing all of this right. I found at work I needed a gui ssh program for my users. So I developed it and it turned into something more than I expected. This was my first ever coding project using Claude, and my first time using GitHub. I decided to make this open source so I could for once give something back to the community instead of just taking. Currently only runs from binaries for Linux. No .rpm, or .deb files. I'd appreciate some feedback if this is something you might want or need for yourself. I forgot to download my screenshots to my phone, but there are a few on the GitHub page.

https://github.com/Brainbeer/ironshell.git

Edit: I had to make modifications to the .gitignore and the binaries should now be available if you don't want to build.

Trying to configure HTTPS with cloudflare DNS and nginx but DNS is unable to resolve on xubuntu local machine but works from inside Oracles VM

I made a post on the oracle cloud subreddit and was advised to post it here as well https://www.reddit.com/r/oraclecloud/s/8pLBlUDath

From inside the oracle VM the DNS resolves to oracles VM IP address but from my local machine it’s unable to resolve the DNS I’m on an xubuntu dual booted (22.04) on windows Idk if it’s a DNS issue from my local machine as it works from inside the oracle VM and also works with 1.1.1.1 and 8.8.8.8 DNS which resolve to the correct IP from my local machine but doesn’t work with my local DNS? Is there any solution to this ? I’m really struggling

ive been trying to setup https with a domain i got off dpdns for free and configured it with cloudflare and added the DNS Records and set them to DNS only grey cloud and pointed them to my oracle public IP, I added the Name Servers to dpdns as well, SSL TLS on Cloudflare is set to Full (strict) with always https on

i then went and setup nginx and did all the necessary to allow lets encrypt certificates to work and all etc

heres my nginx noscript
