For DSP, we already can do that using something like Easy Effects[1][2]. Unfortunately, this isn't shippable for distros. The biggest issue is acquiring proper impulse-response data. In theory, it has to be tuned per-model, and turning basically requires pro-grade equipment and a recording studio. However, apparently many people assume Dolby is using the same profile for all laptops, so just copy-paste the same file here and there. Not really sure which is the real case. Anyways, Asahi can ship DSP turned on by default because the distro is specific to Apple. That's how Apple boosts the quality of its hardware, and the same applies to a distro dedicated to it.

Is this a general comment meant to apply to anything or are you specifically talking about Easy Effects here? It has installation instructions in the README, links to a wiki page with more information (https://github.com/wwmm/easyeffects/wiki/Package-Repositorie...), the application contains full documentation under the "Help" item in the menu (as many applications do) and they also have the same documentation online (https://wwmm.github.io/easyeffects/). Not sure what more you could ask for?

Yeah, Sonos is very much the Apple of this space. A solid, user-friendly implementation of several pre-existing concepts into a cohesive product - no small task. I don't think the technologically important parts of this are patentable though, there's both prior art and the obviousness standard to worry about. But very much like Apple's 'rounded corners' case, they've gone after (IMO) obvious UI functionality for such a system to extract money from their competitors. If you are just interested in the synchronized Audio-over-Ethernet part, AES67 is the industry standard, and a pretty complete open-source implementation can be found at https://github.com/bondagit/aes67-linux-daemon , though AES67 is itself a composition of existing standards, fundamentally it is mostly composed of SDP for sessions description, RTP for media, and PTP for cloc
