What would happen if we simply took the values for all other sample rates from the CS42L42 datasheet and added those to the CS42L84 driver? As it turns out, you get support for those sample rates!

> The patch to enable hardware support for 44.1, 88.2, 176.4 and 192 kHz sample rates on both the input and output of the headphone jack was submitted directly upstream, and has been merged for 7.1. We also backported this to Asahi kernel 6.19.9, allowing users to take advantage of this immediately.

Nice bit of chip sleuthing and reverse engineering from the Asahi team!

whoa, bit perfect CD/flac playback in 44.1, that's a killer feature.

When I think about it, I don't understand why Apple wouldn't want to help this effort and just provide all the documentation. All the classic reasons ("competitive advantage", "secrets", etc) do not hold water in this day and age.

The cynical take is that they make a shit ton of money from services and Linux running on a MacBook won’t help them do that.

They do also make a lot of money selling hardware, and as things stand today that business happens to make them look like the first tech giant to actually profit from the AI boom (because the hardware they've been developing internally for years happens to be among the best consumer-grade options for self-hosting LLMs). Making their hardware more attractive to tinkerers could be a winning move right now.

Linux users don't pay for anything anyway

This, but also you would be allowing people to learn Linux. Developer with a Mac has to be one of the most common linux defectors. I suspect most people don't realize how doable and comfortable the switch can be.

Yeah, and having the only supported OS be MacOS means they can entice people to upgrade when they want. No continuing on with 8+ year old hardware and a lightweight Linux distro even if it's fine for the intended use case.

I imagine the real reason is that if they change things they now have an obligation to promptly share technical docs and if they're slow people will whine and bitch online about them. Not worth it. They have zero to gain (and I say this as someone who would love to dual boot Linux on my M4).

"Amaze, amaze, amaze!" I wonder if there would be interest in an Asahi Remix spin focused on a more Mac-like out-of-the-box experience: cmd as the main modifier key, Mac-like keyboard shortcuts, theming, gestures, etc. Of course, you can tweak any distro however you want, but I think a curated default experience is a different thing.

Cmd as main modifier is lost battle. I've tried it multiple times. In the end just accepted ctrl life and sold my last macbook.
