Funny you should mention audio cutting out on an Intel Arrow Lake or Lunar Lake laptop.
I have an Eluktronics Hydroc 16 (with Intel Arrow Lake), which is also sold as the XMG Neo 16, Tuxedo Stellaris 16, and other brands, and despite Tuxedo having a Linux pre-installed version for sale (I couldn’t buy it due to shipping costs, tariffs, and no US ANSI keyboard option), there has been one issue since launch: The speakers cut out the first second or two of audio and then the rest goes through. Once the audio stops for about 5 seconds, the issue occurs again, and again, and so on. This is really irritating.
I’ve tried almost every distro you can think of, from Fedora, Ubuntu, and Arch, to CachyOS (an Arch-based distro but with a tweaked kernel), and I’ve even tried manually tweaking speakers settings in various tools, but nothing has fixed it.
Unfortuantely, I think you may have to make a report to Fedora and failing that, the LKML (Linux Kernel Mailing List). This may be an upstream firmware loading issue that can be solved from there.
(And BTW, everything else works insanely well on this laptop, including performance modes and keyboard RGB once a modified version of Tuxedo’s TongFang laptop drivers are installed; modified to remove the Tuxedo OEM check. And yes, HDR works, although it’s early days in Linux for HDR, and my games still show it incorrectly no matter what I do, even with the Mini-LED panel.)
The funny thing is that another YouTuber who tested the same specced of Tuxedo Stellaris as mine (just from Tuxedo rather than Eluktronics, but both use the same Tongfang/Uniwell chassis), and he had no such problems with audio afaik (I even asked him personally and he told me there were no audio problems with or without the Tuxedo drivers).
TL;DR, this audio issue may be an kernel firmware loading issue. I’d suggest discussing this with Fedora, and if this can be replicated on other distros like Ubuntu and/or Arch, then it may be worth looking into an LKML report.
