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.

Distorted audio from Focusrite 2i2 (lemmy.ml)

Using KDE plasma, Archlinux, Pipewire, Focusrite 2i2 3rd Gen

Audio from built-in audio and via GPU into display speakers all works fine but audio through my Focusrite is badly distorted, like it is running at super-low quality.

I've spent most of today trying to work out how to make pipewire use the right bit/sample rates. It. This should be a basic GUI feature, and certainly shouldn't need to sudo edit cryptic files to configure this stuff. I use Reaper and I'll need to change bit / sample rates from time to time, so having to make with config files is just nuts. This should be a basic function available in the control panel (Like windows has had for decades). / rant

Anyway, I genuinely want to fix this problem and would really like a GUI tool for it, but a working config edit will do at this point. I can' also make a script to tweak it on demand I suppose.

There is a video that suggests building a new kernel driver for it, which is even more nuts for something so basic.

It's the audio actually clipping from the amplitude being too loud, like distortion on a guitar?

If you're able, you should an example and share it. I am guessing that you're experiencing buffer underruns, and you're recognizing it as something else.

Not like a guitar distortion. More like robotic low quality sound.

"Robotic low quality" sounds like buffer underruns. Any audio example, even from a cell phone held up to speakers, will be fine to help troubleshoot this.

Since this sounds so consistent, I don't think that this is from buffer underruns. It sounds like the frequency of your interface and the frequency that is being sent by your computer are different. Try changing them around and see if you can get it to work that way.
