   I think the idea with the M-series laptops in particular is that you can drive the speakers at volumes that actually damage them very quickly ( see https://github.com/AsahiLinux/linux/issues/53 ). The idea AIUI is that you can use a DSP along with a physical model of the voice coil to get better sound than you would if the speakers were volume-limited.

   For DSP, we already can do that using something like Easy Effects[1][2].

   The biggest issue is acquiring proper impulse-response data. In theory, it has to be tuned per-model, so turning basically require 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.
