@AsahiLinux Oh hey @ygathgoch you were asking about Linux on Mac the other day I think? Haven't used this but just spotted this update.

@AsahiLinux .. macOS only ever programs CS42L84 to operate at either 48 or 96 kHz, we could only add support for those two sample rates to the Linux driver .. However, CS42L42 supports all the other common sample rates, and while the register layout and programming sequence is different, the actual values programmed in for 48 and 96 kHz are the same across both chips. 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! :flan_hacker::flan_thumbs:

@AsahiLinux Even though I don't run @AsahiLinux (I have an m4 machine) I find your progress reports super interesting ❤️
