What's the easiest way to test the latest kernel?
(lemmy.world)
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.

What is the symptom?
Low/distorted audio. Not a "I cant understand this"-type distortion, but a "I can hear and understand if I focus, but its also giving me a headache"-type The issue is not present in Windows 11, and Lenovo support have replaced the speakers once already. I've followed several troubleshooting guides as posted on the Mint forums when users there have similar issues.
I have now tested on later kernels, with interesting results. On 6.14 it showed a generic name for the sound device, but on 6.18+ it seems to correctly identify the device as an 800 series intel device. The audio still sounds the same, however.
Present in headphones?
No, issue is not present in headphones or external speakers, regardles of how they are connected. (Tested on several speakers/headphones connected by jack only, jack+external power, and bluetooth )
That’s weird.
It sounds like there’s an additional amplifier used to drive the internal speakers that isn’t getting turned up. When you fire up alsamixer on the command line do you see more controls than in the gui mixer?
I do, though several of them are stuck on muted or without a tweakable bar. I did, however, come across this today, which seems very relevant. I just haven't had time to test it yet as I've been away.

I haven’t had time to look deeply into the fix posted in that GitHub link, but on first read it seems to be fixing exactly what you’re describing by tying the mixer channels used for the integrated speakers together correctly.
A lot of these newer realtek chips have an insane amount of tweakability. Even back in the day if you were able to settle for their latency you’d get access to a very powerful hardware mixer and sometimes synthesizer.
That was my thinking too. I unfortunately haven't had time to test yet. Between work and a baby, time for this is a bit limited. But I'll give it a try soon. Thank you so much for your interest! I appreciate it.
